Adding a spare while you still have a working key

Bring the existing key

Tell us how many working keys you have and bring them to the appointment. A working key helps identify the correct hardware, but it does not guarantee that every model supports the same add-key procedure.

Choose the right backup

A mechanical blade, a transponder key and a smart fob perform different functions. Confirm whether your backup needs to unlock the door, start the vehicle and operate the remote buttons.

Test both keys

For a supported add-key appointment, the new and existing keys are tested at the vehicle. If all keys are already missing, request an all-keys-lost assessment instead of a duplicate-key quote.

Check model-specific limitations before booking:

FAQ

Service questions.

Can you add a second key if I still have one working key?

For many supported vehicles, yes. Keeping a working key available can make identification and some duplication procedures more straightforward.

Can you duplicate a transponder key or smart key?

Many transponder keys, remotes, and smart keys can be added after the correct part number and vehicle system are confirmed. A key that looks identical is not always compatible.

Will my original key continue to work?

The goal is to add a working backup while retaining the existing authorized key. Both keys are tested before the appointment is completed, subject to the vehicle system.
