A matching appearance is not enough
Part number, frequency, region and the vehicle's security system can affect compatibility. Tell us the year, make and model, and whether you have a working key, before buying a fob.
Customer-supplied keys
If you already purchased a key, ask us to assess it before booking. Some used, locked or incompatible fobs cannot be paired again. Acceptance and programming support must be confirmed for that specific hardware.
Remote buttons and starting
Remote locking and immobilizer authorization may require different procedures. Describe whether the fault affects the buttons, vehicle starting or both, so the requested work can be assessed accurately.
Check model-specific limitations before booking:
FAQ
Service questions.
How long does smart-key programming take?
Timing varies by vehicle and security system. Many supported jobs are completed during one mobile appointment.
Will every smart key work with my car?
No. Frequency, part number, region, and vehicle compatibility matter. Contact us before buying an unverified key online.
How much does key fob programming cost?
Pricing depends on the vehicle, key or fob hardware, whether a working key remains, and the programming procedure. Send the year, make, model, and key details for a confirmed quote.
