Almost every car key since 2000 has used a piece of technology called a transponder. This is an anti-theft chip in the head of the key that has to be correctly programed to work in your specific vehicle. In many cases, these keys cost upwards of $175.00 when going to a dealership. We can offer substantial savings. Also, we are able to do many of the keyless remotes, with lock, unlock, and panic alarm features.
