I am having an issue with the factory alarm. not sure if it even works but I just bought the car a week ago and the buttons didn't work so I replaced the batteries and now the panic button works but the unlock button has no response and the lock button just beeps for about 10 seconds and does nothing. Is there something wrong the remote or possibly the whole system? Thanks

 

First the basics, what year?

And possibly the remote needs reprogramming.

 

It is a 1999 Trooper 3.5L.

Any idea on how to reprogram the alarm?

 

I just tried this about a hundred time and could not get it going? Does anyone know if this is the correct sequenc?

his is from SB98-13-L004. I believe this applies to all 98-2001 Troopers and Rodeos. This is verbatim from the TSB:
