What happens
to your old keys

A car does not recognise keys by their shape. It keeps a short list of chips it trusts, and programming a new key rewrites that list.

Why it deletes the others

If a key was lost or stolen, you want it to stop working. Rewriting the list means anyone holding an old key has a piece of plastic that opens nothing and starts nothing.

The catch

The same rule applies to keys you still own. A spare in a drawer, or a key your partner has at work, stops working the moment the list is rewritten without it.

How not to get caught out

1. Gather every key you want to keep working before we arrive.
2. Tell us about any that are elsewhere; we can wait or come back.
3. If one turns up later, we can add it back to the list.

What we record

We log which keys were deleted and when, so if you ever need to know, we can tell you. The privacy notice covers how that is kept.
