is it an aftermarket alarm or factory fit. if its factory fit you can try to re sync the keys by putting the keys in the ignition turn to the 2nd not starting position then press unlock or lock buttons with the doors shut. locking should then respond.

if its aftermarket try holding both buttons down on the remote until the led stays on release then press lock see if that helps.
