I walked into the store today and sat the alarm. When I walked out, the alarm didn't respond at all. It beep like 3 times and you can see the antenna icon while it was beeping. It showed locked on the responder. But the alarm was disarmed. Now the alarm won't go on or off. When I press the button to lock or unlock, it just beeps at me. It still looks like the alarm is sending signals back and forth because the antenna icon show up every couple seconds. It used to lock the doors when I turn the car on and unlock when I shut the car off. Now nothing. Does anyone have a guess on what it could be before I go to the shop and get ripped?

Thanks....
