To copy a car key, you must prove you are the owner: the logbook (V5C) ideally, OR a proof of ownership (bill of sale, invoice, insurance certificate), plus photo ID in the same name. Without the logbook, one of these alternative documents is enough.
Need a spare or a replacement key, but your logbook is missing, stolen or being reissued? Don't panic: duplication is still possible. For a reputable auto locksmith, the key point is being able to establish that you really are entitled to have the key copied. Here is exactly which documents to have ready, and what to do if the logbook is missing.
The rule is simple: proof of ownership + photo ID. This double check protects the vehicle's owner and puts the professional's liability on the line.
The vehicle registration document (V5C logbook) is the reference document, because it directly links the vehicle to its keeper. But it is not the only one accepted when it is missing (see below).
Passport, driving licence or national identity card. It must be in the same name as the proof of ownership, in order to confirm that you are indeed the person entitled to the service.
A car key opens and starts a high-value asset. By checking your right of ownership, the technician makes sure they are not unknowingly handing over access to a stolen vehicle. It is a protection for you, not an obstacle.
Not having the logbook does not block the job. Several documents can establish your right of ownership.
| Situation | Alternative proof |
|---|---|
| Recently purchased vehicle | Bill of sale + old (cancelled) logbook, or registration confirmation |
| Lost logbook | Loss report + replacement requested from the DVLA |
| Stolen logbook | Police report / crime reference number |
| New vehicle awaiting its logbook | Dealer purchase invoice + certificate of conformity |
| Supporting evidence | Insurance certificate or policy in your name for this vehicle |
In every case, the idea stays the same: a consistent set of elements (document + identity + vehicle present) that shows, beyond doubt, the key is rightfully yours.
If your registration document has disappeared, here is the step-by-step course of action.
Losing your logbook does not mean being stuck. A reputable professional knows how to weigh up a credible alternative proof — while refusing to act if nothing demonstrates your right of ownership.
An operator who agrees to copy your key with no proof at all is doing you a disservice. It means they would apply the same lack of checks to anyone — including someone trying to duplicate the key to a vehicle that is not theirs.
Checking the paperwork is therefore a mark of professionalism. It goes hand in hand with other guarantees: professional liability insurance, prices announced in advance, and a traceable job in line with data-protection rules.
