When a key fob stops locking, unlocking, or starting your car, a car locksmith can test it, replace the battery, or supply and program a new fob to your vehicle.
The most common reason a fob quits is a dead coin-cell battery, which is inexpensive to swap. If a fresh battery does not restore function, the fob may need re-syncing or full replacement and programming. A locksmith can quickly determine which fix applies so you do not pay for a new fob you did not need.
You can choose an original-equipment fob that matches the factory unit exactly, or a quality aftermarket fob that often costs less while still handling lock, unlock, and trunk functions. Whichever you pick, the fob must be programmed to your specific car before it will operate.
