1.Disarm
2.Turn ignition on
3.press and hold the smaller of the two buttons on the fob until you hear a beep.
This is service mode but you still get a beep every few seconds which will drive you nuts! It must have a backup battery built in because it continues even without the battery.
You can take it out of service mode by pressing the arm/disarm button
