These alarm fobs can easily go out of sync, even passing through sliding doors in supermarkets etc.. can cause this to happen. To rysync the fob to the alarm, stand within normal operating distance to your car and press the on/off button (left button) and hold button pressed in for at least 10 seconds. Release button, then press on/off again, your fob should now be functioning correctly. You may need to repeat this procedure a few times to get it right. I have had to do it a couple of times on my Toyota Celica (Scorpion 5000 Alarm) and it has worked successfully for me.
