What Documents Do You Need to Get a Replacement Car Key?

Losing your car key can be stressful – but getting a replacement isn’t as simple as walking in and asking for one. Because modern car keys are coded to your specific vehicle, proof of ownership is essential before a new key can be supplied and programmed.

So, what paperwork do you actually need to bring with you? Let’s break it down.

Why documents are required

Car keys are tied directly to your car’s security system. Without proof of ownership, anyone could try to order a key and drive away in a vehicle they don’t own.

Requiring documents protects you and prevents car theft. It also ensures that the replacement key is correctly coded to your exact make, model, and VIN.

The key documents you’ll need

When ordering a replacement car key, be prepared to show:

V5C logbook (Vehicle Registration Certificate) – This proves you are the registered keeper of the car.
Driving licence or photo ID – Confirms your identity.
Proof of address – Sometimes requested to match against the V5C.
Vehicle Identification Number (VIN) – Found on the windscreen plate, door frame, or inside the engine bay.

Together, these documents give the locksmith, dealer, or specialist workshop the authority to cut and program a new key for your vehicle.

Additional details that help

Alongside the required documents, it’s useful to provide:

The make, model, and year of your car.
Existing spare key (if you have one).
Key code card (sometimes supplied when the car is new).

The more information you can provide, the quicker the process.

Can you get a replacement without documents?

In short: no.
Without proof of ownership, no legitimate workshop or locksmith will supply a key. If your documents are missing, you’ll first need to apply for replacements (for example, a new V5C from the DVLA).

Why use a professional service?

Professional workshops like Technical Vehicle Solutions don’t just cut keys, we:

Verify ownership with the right paperwork.

So, what documents do you need for a replacement car key?

To summarise:

V5C logbook.
Driving licence or photo ID.
VIN and basic vehicle details.

Bring these with you, and getting a new key is a straightforward process.
