IN-DEPTH GUIDE
Key Fob Programming for Supported Vehicles
“Key fob” can describe several devices: a simple lock/unlock remote, a remote key with a mechanical blade, or a proximity smart key. The programming method therefore depends on what the fob actually controls and how the vehicle authorizes starting.
Compatibility is more important than appearance. Two fobs can share the same case while using different electronics, frequencies or board types. We identify the vehicle and existing key system before confirming a replacement fob.
If the existing fob has stopped working, diagnosis may be better than immediate reprogramming. Battery condition, button damage and board faults should be considered first.
Before you contact us
For vehicle work, send the make, model, year, start type and photos of any existing key. For door and lock work, send clear photos of the lock, door edge and key where possible. This helps us confirm the correct service, likely parts and whether shop or mobile service is suitable.
SERVICE DETAILS
What to Know Before You Book
Key fob is a broad term covering remotes, proximity fobs and smart keys. The correct programming method depends on what the fob actually controls.
Compatibility can depend on frequency, transponder type, part number and vehicle market. Matching the appearance alone is not enough.
We confirm the vehicle and fob details first, then test the supported functions after programming.

More About Key Fob Programming
How we identify the right service
A vehicle key problem is not always a programming problem, and a lock problem is not always solved by replacing the lock. For Key Fob Programming, we start with the vehicle make, model, year, start type and the exact symptom. We also ask whether a working key remains, whether the mechanical blade still operates the door or ignition, and which electronic functions still work. These details help separate cutting, transponder, remote, smart-key, lock and vehicle-side issues before parts or labour are committed.
Working key versus all keys lost
The service path can change significantly depending on whether at least one working key is still available. A spare-key job normally begins by identifying the existing key and matching a compatible replacement. When all keys are lost, the vehicle may require a different security procedure, authorized access, additional key generation steps or a different programming route. We therefore quote and plan all-keys-lost work separately instead of treating it as ordinary duplication.
Cutting, programming and remote functions are different
Modern car keys can combine several systems in one case. The blade provides mechanical access, the transponder communicates with the immobilizer, and remote or smart-key electronics control locking, unlocking or proximity functions. One part can work while another fails. A newly cut blade may open the door but not start the engine; a transponder may start the car while remote buttons remain faulty. Our service process checks the functions relevant to the key instead of assuming one procedure fixes everything.
Compatibility before parts are ordered
Keys and remotes that look identical can contain different chips, frequencies, boards or smart-key specifications. Vehicle market and production year can also matter. For that reason, send clear photos of the existing key and any available identifiers together with the vehicle details before purchasing a replacement. We confirm the likely compatible option first and explain when final confirmation requires inspection of the vehicle or key.
What affects the final price
Pricing for Key Fob Programming depends on the vehicle, key or lock system, whether a working key remains, the replacement part required, cutting requirements, programming method and whether the job is completed at the shop or at the vehicle. An all-keys-lost job is not priced the same as adding a spare. Contact us with the full details and we will explain the expected work before proceeding.
Security and handover
Car-key and vehicle-access work is security-sensitive. We may request reasonable evidence that the person requesting the work owns or is authorized to use the vehicle. After the supported work is completed, the relevant mechanical and electronic functions are tested before handover. If another vehicle-side fault remains, we explain what was confirmed during the locksmith work rather than presenting an unrelated fault as a key problem.
