Hi, sounds like you'll need to reprogram the remote to the alarm (changing batteries wont help matters). There should be a keypad in the car, allowing you to use your PIN to do this. The only problem would be if you 1. havent got a pin 2. havent got a keypad. If this is the case youll have to send the alarm off to a place like TECH-TRONICS in MCR who'll prog it for you or supply you with a keypad if you need it.
