If someone keys your car, document the vehicle before cleaning it, report intentional damage to the police, preserve nearby video, and contact your insurer before authorizing repairs. Check scratch depth immediately: clear-coat damage may polish out, while exposed primer or metal needs paint protection and usually professional repair.
Key Facts at a Glance
Car keying is intentional vandalism, and comprehensive auto insurance commonly covers it when that coverage applies.
Collision coverage generally addresses impact damage, not deliberate scratching by another person.
A white or gray line often indicates primer or base-coat exposure; silver metal indicates the deepest damage.
The insurance decision depends on repair cost, deductible, policy terms, and the effect of a claim on future premiums.
Do not aggressively compound, wet-sand, or apply household cleaners before documenting the evidence.
A bare-metal scratch should receive prompt corrosion protection because moisture can begin oxidation before visible rust appears.
What to Do if Someone Keys Your Car
The correct response to a keyed car has seven priorities: safety, documentation, evidence, police reporting, insurance review, temporary protection, and repair selection. Complete the first five before polishing or touching up the paint, because cleaning can remove paint transfer or alter evidence that helps identify the responsible person.
Before you touch the vehicle
Move away from the car if you believe the vandal is nearby. A fresh confrontation can create a personal-safety problem and may turn property damage into an assault or harassment incident. Call emergency services if there is an immediate threat, an active crime, or an injury; use the police non-emergency line for damage discovered after the event.
Photograph the whole vehicle from several angles, then capture each mark close enough to show its direction, length, paint loss, and surrounding transfer. Include a ruler, coin, or measuring tape beside representative scratches, but do not place the object inside the damage. Write down the discovery time, last known undamaged time, exact location, weather, nearby vehicles, and anyone who had lawful access.
Seven actions in the correct order
- Secure your safety. Do not confront a suspected person or enter a dark parking area alone.
- Photograph the scene. Take wide, medium, and close images before washing the panel.
- Make an incident log. Record dates, location, affected panels, witnesses, and visible debris.
- Request nearby video. Ask businesses, property managers, and neighbors to preserve relevant footage.
- File a police report. Obtain the incident or case number and keep the report copy.
- Call your insurer. Confirm comprehensive coverage, deductible, claim requirements, and rental benefits.
- Protect and repair the paint. Clean gently, seal appropriate damage, and obtain estimates.
A police report is not a guarantee of recovery, and an insurer may not legally require one in every jurisdiction or policy. Nevertheless, the report creates a contemporaneous record and can connect separate vandalism incidents in the same area.
How Deep Is the Scratch?
Scratch depth determines whether polishing can restore the finish or whether the panel requires color, primer, clear coat, or a complete respray. Automotive paint normally consists of a substrate, corrosion protection or primer, colored base coat, and transparent clear coat, so each deeper layer increases repair complexity.
A practical depth assessment
Wash the panel with automotive shampoo, clean water, and a soft microfiber towel only after taking evidence photographs. Dirt can make a superficial mark look deeper, while transferred paint from the key or another object can make a deep cut look deceptively shallow.
Run a clean fingernail lightly across the scratch. If the nail does not catch and the mark disappears when the panel is wet, the damage may be limited to clear coat. If the nail catches, color is missing, or the line remains visible when wet, polishing alone may not restore it.
Do not use the fingernail test as a substitute for a paint-depth gauge. A paint meter measures total coating thickness, not the exact depth of one groove, and readings vary across steel, aluminum, plastic, repaired panels, and factory edges.
| Visible condition | Likely affected layer | Sensible first repair | Rust risk |
|---|---|---|---|
| Gloss loss with no color change | Clear coat | Fine polish or machine correction | None from exposed metal |
| Dark or dull line that disappears wet | Clear coat or transfer | Wash, clay if needed, then polish | None if color remains intact |
| White, gray, or colored streak | Base coat or primer | Color-matched touch-up or spot repair | Low on plastic, moderate on steel |
| Silver line or visible substrate | Bare steel or aluminum | Primer, paint, and clear coat | High on exposed steel |
| Scratch across an edge with flaking paint | Multiple layers and panel edge | Body-shop inspection | High if steel is exposed |
| Dent, crease, or broken trim beside scratch | Paint and panel structure | Body repair before refinishing | Depends on substrate |
A scratch through a plastic bumper will not rust, but it can still expose textured substrate and require refinishing for a uniform appearance. Steel doors, fenders, quarter panels, and hoods need faster corrosion control when the scratch reaches metal.
How Can You Find and Preserve Evidence?
Nearby cameras and witnesses can identify the event, but video systems frequently overwrite recordings within 24-72 hours. Ask for preservation immediately, even if the owner cannot release footage without police involvement or a formal request.
Check the following sources:
- Apartment, condominium, and office security systems
- Gas stations, supermarkets, restaurants, and parking garages
- Residential doorbells facing the street or parking area
- Dashcams with parking mode and internal memory cards
- Vehicle cameras, alarm systems, or manufacturer security applications
- Employees, attendants, delivery drivers, and nearby residents
Give the property owner a narrow time window, vehicle description, parking position, and direction of travel. Ask the owner to preserve the original file rather than sending a compressed social-media copy. Do not trespass, bypass a password, remove an SD card without permission, or publish an accusation based on an ambiguous image.
The National Insurance Crime Bureau recommends reporting suspected insurance crime and vehicle-related fraud through its official channels, while local police control the vandalism report. Keep original photographs with their file dates, and store copies in two locations.
When Should You File a Police Report?
File a police report when the damage appears intentional, when you have possible suspect information, when cameras or witnesses may exist, or when an insurer, lender, fleet operator, or leasing company requests documentation. Use the non-emergency line or an online reporting portal where the jurisdiction permits property-damage reports.
Tell the officer or online system:
- When the vehicle was last confirmed undamaged
- Where it was parked and whether the location had cameras
- Which panels were damaged and the approximate scratch lengths
- Whether paint, a tool, note, threat, or other object was left behind
- Names and contact details for witnesses
- Whether similar vehicles were damaged nearby
- Any suspected motive, without presenting speculation as fact
Request the case number, report number, reporting officer details, and instructions for obtaining the completed report. Police may not attend for a nonviolent scratch, and they may classify the incident as criminal mischief, vandalism, or property damage according to local law.
If the scratch accompanies a threat, stalking, hate-motivated message, repeated harassment, or an attempt to damage the vehicle while occupied, explain those facts explicitly. Those circumstances can change the appropriate response and may warrant immediate emergency assistance.
Does Insurance Cover Car Keying?
Comprehensive auto insurance usually covers vandalism, including intentional paint damage, subject to the policy deductible and exclusions. Collision coverage generally does not cover a keyed car because collision insurance addresses impact with another vehicle or object, although policy definitions and bundled coverage differ by insurer and jurisdiction.
The Insurance Information Institute describes comprehensive coverage as protection for non-collision events such as theft, fire, vandalism, and weather-related damage. Confirm the current policy wording rather than relying on a coverage label from an old insurance card.
Calculate the claim threshold
Compare the written repair estimate with the comprehensive deductible. For example, a $500 deductible on a $900 repair produces a theoretical $400 insurance payment before policy-specific limitations, while a $600 repair produces only $100. A small payment may not justify a claim if your insurer considers claim history in pricing, but only the insurer can explain the underwriting effect.
| Repair estimate | Comprehensive deductible | Approximate insurer payment | Practical question |
|---|---|---|---|
| $350 | $500 | $0 | Pay privately unless other damage appears |
| $900 | $500 | $400 | Compare claim history and repair urgency |
| $1,500 | $500 | $1,000 | A comprehensive claim may be reasonable |
| $2,400 | $1,000 | $1,400 | Confirm coverage and panel scope first |
| $4,000 | $1,000 | $3,000 | Report promptly and use an approved repairer if useful |
Ask whether the policy includes rental reimbursement, diminished-value treatment, OEM-parts requirements, mobile-app inspection, repair-shop restrictions, and a deadline for reporting. Do not authorize a full repaint before the insurer inspects the damage if you may claim it. Save estimates, receipts, police records, photographs, and correspondence.
A lender or leasing company may require repairs even when the owner prefers a low-cost cosmetic solution. Read the finance or lease agreement before accepting a touch-up that leaves visible paint loss.
How Do You Protect the Scratch?
Clean the damaged panel with automotive soap and a microfiber towel, dry it completely, and protect exposed steel from water until permanent repair. Wax alone is not a reliable rust-prevention system for a deep cut because wax can leave contamination in the groove and does not replace primer.
For a short delay, use a clean, dry temporary automotive sealant only when the surface is free of dirt and moisture. A body shop may need to remove that product before refinishing, so tell the repairer what you applied. Do not cover a wet scratch, use household oil, spray lubricant, nail polish, or a thick layer of wax over debris.
Temporary protection by substrate
| Substrate | Short-term action | Avoid | Repair urgency |
|---|---|---|---|
| Clear coat | Wash, dry, and avoid abrasion | Compound applied repeatedly | Schedule within days or weeks |
| Base coat | Clean and keep dry | Scrubbing to restore shine | Arrange paint repair when practical |
| Steel | Clean, dry, and use compatible temporary protection | Water, salt, and household sealants | Arrange promptly, preferably within days |
| Aluminum | Clean and dry, then obtain repair advice | Aggressive sanding that contaminates the panel | Arrange promptly |
| Plastic bumper | Clean and protect from further scuffing | Metal-rust assumptions | Cosmetic urgency depends on appearance |
Road salt, coastal humidity, repeated rain, and winter temperatures increase the need for prompt repair. Rust does not usually transform a clean scratch into structural failure overnight, but corrosion can spread beneath surrounding paint and enlarge the area a technician must sand.
Which Repair Option Fits the Damage?
Clear-coat marks are candidates for polishing, while scratches that remove color or expose substrate need paint. DIY methods cost less but create a greater risk of visible texture, haloing, color mismatch, and excessive clear-coat removal.
| Repair method | Typical cost | Typical time | Best use | Main limitation |
|---|---|---|---|---|
| Scratch-removal kit | $15-$40 | 1-2 hours | One shallow clear-coat mark | Cannot replace missing color |
| OEM touch-up paint | $25-$60 | 1-2 days including curing | Small isolated chips or cuts | Raised or visible repair line |
| Mobile paint correction | $150-$400 | 3-6 hours | Several shallow marks | Cannot rebuild deep layers |
| SMART or spot repair | $250-$800 | 1-2 days | Limited damage on one panel | Color blending may remain visible |
| Body-shop panel refinish | $400-$1,500+ | 2-5 days | Deep, long, or multi-panel keying | Higher cost and vehicle downtime |
| Full side or multi-panel repair | $1,200-$4,000+ | 3-7 days | Continuous vandalism across panels | Estimate depends on blending and trim |
When is DIY repair reasonable?
DIY polishing is reasonable when the scratch is shallow, the paint remains present, and the owner accepts that the result may not be perfect under direct light. Use a clean applicator, a mild finishing compound, and limited passes; stop if the gloss changes unevenly or the mark remains after a few controlled attempts.
An OEM touch-up pen is more appropriate for a small deep cut than a polishing kit. Locate the factory paint code inside the driver-side door jamb, under the hood, in the glove box, or in manufacturer records. Generic “black,” “white,” or “silver” paint rarely matches metallic flake, pearl, or three-stage finishes.
Do not wet-sand a raised touch-up repair unless you understand film thickness and polishing. A 3000-grit abrasive can level a cured high spot, but it can also remove surrounding clear coat and create a larger dull patch. Touch-up paint does not reproduce factory spray texture or professional color blending.
When should a professional repair the panel?
Choose a body shop when the scratch exposes metal, crosses an edge, spans several panels, includes a dent, affects a new or high-value vehicle, or will be inspected at lease return. A professional can measure the panel, identify previous repairs, blend adjacent paint, remove trim, apply corrosion protection, and restore clear-coat thickness more consistently.
A detailer can correct surface damage but cannot replace missing primer or base coat. That limitation matters: polishing a deep groove may make the surrounding panel shinier while leaving the actual defect unchanged.
How Much Does Repair Cost?
Keyed-car repair typically ranges from $15 for a small DIY correction to more than $1,500 for deep damage across a panel, with luxury finishes and multi-panel blending increasing the bill. The dominant price drivers are scratch depth, total length, number of panels, paint type, trim removal, and whether the panel needs metal repair.
What changes the estimate?
A short scratch on one steel door may need localized preparation and paint. A continuous line across a door, fender, and quarter panel often requires blending or refinishing multiple panels so the color transition does not show under sunlight.
Ask each repairer to separate:
- Sanding and surface preparation
- Primer or corrosion treatment
- Base-coat and clear-coat application
- Adjacent-panel blending
- Trim, molding, mirror, or handle removal
- Dent repair and alignment
- Taxes, shop supplies, storage, and rental-car charges
- Warranty period and warranty exclusions
Get at least two written estimates for nonurgent private-pay work. A low estimate that omits blending or trim removal may become more expensive after disassembly. Insurance-approved repair networks can simplify claims, but vehicle owners generally should understand who controls the repair choice under applicable local law.
What Should You Avoid?
The most damaging response is aggressive cosmetic work before evidence collection or depth assessment. Household abrasives and repeated machine polishing can remove sound clear coat, enlarge the visible repair boundary, and reduce the options available to a professional technician.
Avoid these common mistakes:
| Mistake | Why it causes trouble | Safer correction |
|---|---|---|
| Washing before photographing | Removes transfer and changes evidence | Document first, clean second |
| Using dish soap repeatedly | Can strip protection and leave residue | Use pH-balanced automotive shampoo |
| Rubbing toothpaste or baking soda | Abrasive particles create haze | Use a purpose-made automotive polish |
| Filing a claim before an estimate | Deductible may exceed the repair cost | Obtain a realistic written estimate |
| Touching up with generic paint | Metallic and pearl colors mismatch | Use the manufacturer paint code |
| Sanding an uncured pen repair | Smears paint and enlarges the defect | Follow the product cure time |
| Applying wax over wet metal | Traps moisture and contamination | Dry fully and use compatible protection |
| Confronting a suspected vandal | Creates safety and legal risk | Preserve evidence and report facts |
A common practitioner rule is to stop DIY work after one controlled polish test fails. More rubbing rarely converts a base-coat scratch into a clear-coat scratch; it more often reduces the surrounding coating.
Can the Scratch Be Repaired Without Repainting?
A keyed-car scratch can be repaired without repainting only when the damage remains within the clear coat or consists mainly of removable paint transfer. Missing base coat, primer, or metal cannot be restored by polishing because polishing removes material rather than adding the lost paint layers.
A technician can test a small section with a mild polish, inspect it under strong white light, and compare the result from several angles. If the groove remains visible when wet, catches a fingernail, or shows a contrasting substrate, repainting or touch-up is required.
Clear-coat correction also has a limit. Factory clear coat is finite, and a technician should not chase a scratch until the surrounding finish becomes dangerously thin. On a previously refinished panel, the safe polishing margin may be lower than on untouched factory paint.
Which Situations Need a Different Strategy?
Vehicle ownership, location, finish type, and repeated harassment change the best response. A leased vehicle needs documented, professional-quality correction, while an older low-value car may justify sealing the damage and paying privately if the repair exceeds the vehicle’s cosmetic value.
Leased or financed vehicles
Contact the leasing company before repair if the damage could appear in an end-of-term inspection. Keep before-and-after photographs, invoices, paint-code records, and the repair warranty. A poor touch-up can cost more at inspection than a properly blended repair because inspectors assess finish quality, not merely whether the groove is filled.
Financed owners should check lender requirements for significant body damage. Comprehensive insurance may pay for covered repairs, but the owner remains responsible for the deductible and any policy exclusions.
High-value, classic, or unusual paint
New, luxury, matte, satin, tri-coat, and factory-protected vehicles deserve a body-shop assessment before polishing. Matte paint cannot be spot-polished like gloss paint because polishing creates a shiny patch; matching a tri-coat finish also requires controlled color blending.
Classic cars and vehicles with prior repainting may have nonstandard paint thickness, oxidation, or difficult-to-source colors. Photograph the damage, document the paint code if available, and obtain a specialist estimate rather than treating the vehicle like a modern single-stage repair.
Repeated vandalism or suspected harassment
Repeated keying should be treated as a security and personal-safety issue, not only a cosmetic repair. Provide police with prior report numbers, vary parking locations, improve lighting, ask property management about camera angles, and preserve threatening notes or messages without handling them unnecessarily.
Do not place a hidden camera where it violates local privacy law. A visible, lawfully installed camera aimed at your own parking area is safer than secretly recording private spaces or confronting a neighbor.
How Do You Choose a Repairer?
Choose a repairer by matching capability to damage, not by selecting the lowest advertised price. Ask whether the business performs paint correction, spot repair, full-panel refinishing, corrosion treatment, color blending, and work on your vehicle’s paint type.
Use these screening questions:
- Will you inspect the panel under direct and artificial light?
- Does the estimate include primer, base coat, clear coat, and blending?
- Will you remove trim or mask around it?
- What paint system and color-code process will you use?
- How long must the vehicle remain at the facility?
- What warranty covers peeling, mismatch, or clear-coat failure?
- Can you provide photographs of comparable repairs?
- Will the repair preserve lease-return or manufacturer requirements?
A professional mobile detailer is suitable for clear-coat correction, not deep metal exposure. A body shop is the safer choice for corrosion treatment, panel-edge damage, multiple panels, or a finish that must pass close inspection.
The Bottom Line
If you are deciding what to do if someone keys your car, photograph the untouched damage, preserve video, file a police report, compare the repair estimate with your comprehensive deductible, and protect exposed metal before arranging repair. Polish only clear-coat damage; use coded touch-up paint for small deep marks; choose a body shop for metal, multi-panel, leased, luxury, matte, or high-value vehicles.
The most cost-effective decision is usually based on four facts: visible layer damage, panel count, insurance deductible, and required finish quality. Delay cosmetic decisions until evidence is secure, but do not leave bare steel exposed through repeated rain or road salt.
Frequently Asked Questions
Will my insurance rates increase after a vandalism claim?
A vandalism claim is generally handled under comprehensive coverage rather than collision coverage, but pricing consequences depend on the insurer, state or country, claim history, and underwriting rules. Ask the insurer whether a claim inquiry is recorded, whether reporting is required, and how a paid comprehensive claim may affect renewal.
Is a keyed car still safe to drive?
A keyed car is usually safe to drive when the damage is limited to painted exterior panels and no glass, lighting, tire, lock, mirror, camera, or structural component is affected. Inspect the vehicle before driving, because deliberate vandalism can include punctured tires, broken mirrors, or damaged sensors that create a safety hazard.
How long can I wait before repairing a deep scratch?
Arrange repair within days when bare steel is visible, particularly in wet, salty, or coastal conditions. A clean clear-coat scratch can wait longer without rust risk, but leaving any exposed substrate dirty or wet increases preparation work and can allow corrosion or paint lifting.
Can I remove a keyed-car mark with WD-40?
WD-40 may loosen some surface contamination or transferred material, but it does not repair a scratch through clear coat, base coat, or primer. It can also leave residue that complicates refinishing. Use automotive shampoo first, then have a detailer test safe solvent or polish on a small area.
Does a police report prove who keyed my car?
A police report documents the allegation, observed damage, timing, location, and available evidence; it does not by itself establish the perpetrator’s identity. Camera footage, witnesses, admissions, physical evidence, and corroborating incidents may support an investigation, while speculation should remain clearly separated from documented facts.
Should I tell my insurer before getting a repair estimate?
Yes, contact the insurer before authorizing substantial work if you may submit a claim. Ask about inspection requirements, approved repair procedures, deductible, rental coverage, and evidence rules. You can usually obtain an estimate first, but do not allow permanent repair to remove evidence before the insurer gives instructions.
