Lost keys: what to do first
A lost set of keys is a security problem as well as an inconvenience: whoever finds them may know where you live. Keys are small, usually have no name on them, and are among the items most often handed in by strangers. This page explains what to do first, how to describe keys so only the owner can claim them, how reporting and matching work on DokiFinder, and how to avoid losing them again. Reporting is free.
What people lose in this category
House and flat keys fall out of pockets on buses, in parks and at the gym. Car keys and key fobs are left on restaurant tables and in shop changing rooms. Bicycle locks, mailbox keys, office badges and keyrings with small tokens are found on pavements and train platforms every day.
The first hours
Retrace your steps and ask at the places you visited. If the keys carry an address or could be linked to your home, consider changing the lock barrel or telling your landlord; for a car, ask the dealer about a replacement and, where possible, disabling the lost fob. Tell a person who has a spare so you can get in, and do not leave a spare under the doormat.
How to describe keys
Give the number of keys, their shape and colour, the keyring or tag, any tokens or fobs, and the brand of the car or lock if you know it. Do not publish your address or anything that links the keys to your home. Describe one detail you will keep back, such as the number stamped on a key, and give it only when you claim.
How reporting works on DokiFinder
Post a lost report with a photo of the same type of keyring if you have one, the place and the time. It is compared with found reports from individuals and from transport operators, venues and organizations that log found items. A finder reports what they found without your contact details, and the handover is agreed in the platform's chat after you prove the keys are yours.
Prevention
Keep keys in a fixed pocket, add a visible tag with a phone number or an email, not an address, and give a spare to someone you trust. A keyring that clips to a bag is harder to leave behind.
Frequently asked questions
Should I change my locks after losing keys?
If the keys could be linked to your address, it is safest to do so, or to ask your landlord. A car dealer can advise on the fob.
How do I prove keys are mine?
Describe a detail only you know, such as the number stamped on a key, the keyring contents, or show that the keys open your lock.
Should I put my address on the keys' tag?
No. Use an email address or a phone number instead.
Is reporting free?
Yes. If you offer a reward, it is held securely until the return is confirmed.
I found keys. What should I do?
Post a found report with the place and time, and arrange the return through the platform. The owner must describe a detail that is not visible in the listing.
