Car key programming without a dealer wait
Whether you need a spare key, a replacement smart key, a proximity fob or lost-key programming, the main goal is simple: get a working key programmed and tested without unnecessary dealer delays.
Send your registration, the number of keys you currently have, and whether the car uses a blade key, remote key or push-button start. We will confirm price and availability before booking.
When customers usually book
- Spare key: Avoid being stuck if your only key is lost or damaged.
- Lost key: Programming route depends on vehicle security system and available data.
- Remote not working: Key, battery, transponder or module faults can look similar at first.
- Smart / proximity key: Fobs need correct programming and on-car testing before handover.
