Modern car keys are cheap to cut but costly to program to the car's immobiliser. The smartest money is spent now, having a spare made while you still have a working key, before you lose it and pay the all-keys-lost premium.
💰 Ways to save
- Get a spare key made now while you have a working one, it is far cheaper than an all-keys-lost job.
- An auto locksmith is usually cheaper than a dealership for cutting and programming.
- Confirm the key type before quoting, a smart proximity key costs far more than a basic transponder.
