Ok, alarm remote stopped working, I replaced the battery. Same thing, still did not work. The alarm automatically engages when the car is shut-off and locked. BUT, WHEN MY ALARM WENT OFF, I WAS IN THE MIDDLE OF CHANGING THE REMOTE BATTERY. AFTER I CHANGED IT, THE REMOTE STILL DID NOT WORK. I TRIED TO START MY CAR, (ALARM BLARING) BUT IT DID NOT START, AND STILL WONT. So then, why doesnt my car start when I use the key and why dose'nt my remote work? Any answers, please.
