Key drop-box return and a damage charge

Updated 15 October 2026
General information, not legal advice. The outcome depends on the facts of your case.

You returned the car early in the morning or late at night, parked it and dropped the key in a box. Nobody checked the car with you. Days later, a damage charge arrives. Key-drop returns are one of the most common sources of damage disputes, and one where the rental company's evidence matters most.

Why it matters that nobody checked the car

After a key drop, the car can stand in a car park for hours before anyone inspects it. Other cars park next to it. Staff move it. If the damage was found later, the question is not only whether the damage exists, but when it happened: before you left it, or after.

The UK competition authority said in 2015 that making customers liable for damage after an out-of-hours return, without regard to when it happened, may be unfair. Leaseurope's guidelines for rental companies say customers who return out of hours should be told when their responsibility for the car ends, and should be encouraged to take photos.

Ask for the timeline

In your letter to the company, ask for:

• the time the key was dropped, from the key-drop log;
• the time the car was inspected, and by whom;
• where the car was parked between your return and the inspection, and whether anyone moved it;
• the photos of the damage, with dates and times;
• the check-out report from pick-up, so you can compare;
• at least 2 repair quotes, or the real repair invoice, and how the amount was calculated.

Also ask for the charge to be put on hold while you dispute it.

Your own evidence

Your best evidence is what you recorded yourself:

• photos or a video of the car at the return spot, all sides, with the time in the file;
• the same from pick-up, if you have them;
• the parking ticket, fuel receipt or toll receipt that shows when you were there;
• any email or text confirming the return.

Keep the original files. A photo sent by messaging apps can lose its date and time.

Be careful with one point

If there was no check-out report at pick-up, some countries' law presumes you received the car in good condition. In Spain, for example, the Civil Code says so. That makes your own pick-up photos important. If you have none, your case rests more on the gap between return and inspection, and on whether the amount is proven.

Next steps

1. Write to the company with the questions above.
2. Wait for its final answer in writing.
3. Use the right free dispute body: ECRCS for cross-border rentals booked direct with a member brand, BVRLA for UK rentals, or the European Consumer Centre.
4. If those routes are closed, dispute the charge with your card issuer. See our card dispute guide.
