If you have a key and it has worked in the past but has now stopped working, it could be the battery. Of course, that is assuming you didn't drop the keys in some water. Newer cars have keys that are chipped. Meaning they have a computer chip embedded in the head of the key itself. With our locksmith shop on wheels, we can save the day. Desert Locksmith can come to you and reprogram your car key, replace the battery, or supply you with a new transponder key.
