I've been reading through some previous posts concerning keyless entry and most deal with programming a new key. My key just stopped locking/unlocking the doors. I have put a new battery in the key so I ruled that out. Is there something like a transmitter (or something like that) that I can check to see if it's still in working order before I attempt to reprogram the key as if it were a new master key?

Thanks guys....

 

Does the light on your remote light up when you push the Lock/Unlock buttons?

 

Yes, the light does blink when I push one of the buttons. Its not a very bright but it does blink rapidly.
