I guess you mean the remote control for locking/unlocking and deactivating the immobiliser. If so as far as I know you wont lose the code the memory unit that holds the codes has a battery back up its self I wouldn't leave it disconnected for weeks but a few hours no problem. however don't forget if you have an audio system that requires a code...that will lose its brain..hope this helps...
