I too have a question about my fob. I tossed my keys to my son one day (he's 4) he failed to make the catch and they hit the driveway. When they landed the fob came apart into 3 pieces. I put the battery in and put it back together. It has never worked again... Will the dealer give me a new one?
Not if they find damage. First, make sure the battery is in correctly. If it is look closely at the metal piece that holds the battery in place. The solder connections aren't particularly strong anyway and may have broken loose. These can be resoldered instead of replacing the key.
