Changing the battery on a Viper alarms key fob is very easy to do. The back of the key ob. comes off and the battery is located inside. Simply change out the battery with a new one and replace the back of the key fob.
If you know for sure that the alarm is functioning correctly, but the key-fob doesn't operate - either the fob is faulty or the battery is flat. Replace the battery - if the fob operates the alarm, then the battery was flat. If the alarm still doesn't operate, then the fob is faulty. You can always test the battery with a multimeter - although you may have to dismantle the remote to get at the battery !
