Key Fob Programming Issues

Sometimes, the key fob may lose its programming and need to be reprogrammed to communicate with your car.

How to Check: Try your spare key fob. If it works, then the issue is likely with the programming of the original fob.

Faulty Key Fob

Over time, the internal components of a key fob can wear out or become damaged.

How to Fix: In this case, you will need to replace the key fob. You can purchase a new one from a dealership or a reputable online retailer.
