Remote Control stop working
 

Hi all, about to leave work yesterday, only to realise my remote control would not open the doors. Tried the sensors as i usually do before taking out the remote itself and pressing it. Still nothing. Had to use the key and enter. After which the alarm went off. But it stopped after about 20 or 30 seconds. Then i was able to start the jeep with the key inserted.
Do anybody know whats happening in my situation??

Battery is death ?
Or maybe the key get deprogram
try your other key
