I OWN A 2000 JXI CONV,THAT I PURCHASED IN 2006 AND MY REMOTE STOPPED WORKING SO I CHANGED THE BATTERY AND IT STILL WILL NOT WORK AFTER CHANGING THE BATTERY. I HAD NEVER NOTICED THAT THERE WAS AN ALARM ON THIS CAR, THERE WAS NEVER ANY FLASHING LIGHTS OR ANYTHING. JUST ALL OF A SUDDEN WHEN I WENT TO ENTER MY CAR THE ALARM WENT OFF, AND WITH THE REMOTE NOT WORKING I COULD NOT STOP THE ALARM, EVEN AFTER STARTING THE CAR, DRIVING WITH LIGHTS FLASHING. NOW THE ALARM SETS MOST OF THE TIME WHEN I EXIT THE CAR, BUT I CANNOT USE THE KEY IN THE DRIVERS DOOR, BECAUSE IT WILL NOR UN-ARM THE ALARM, AND IF THE ALARM DID NOT PREVIOUSLY COME ON WHEN I LOCKED THE CAR IT COME ON WHEN I TRY TO UNLOCK THE CAR. I HAVE TO GO TO THE PASSENGER SIDE DOOR TO UNLOCK THE DOORS. I TRIED TO RE-SYNCHRONIZE THE REMOTE WITH THE CAR BUT WITH THE REMOTE BUTTONS NOT WORKING IT DID NOT WORK. THERE MUST BE SOME TYPE OF ELECTRICAL SHORT IN THE CAR WHY IT REMOTE/ ALARM WILL NOT WORK PROPERLY. ALSO SOMETIMES WHEN I JUST PUT THE KEY IN THE DOOR WITHOUT TURNING IT WILL UNLOCK THE DOORS. NOW THE TRUNK WILL NOT STAY OPEN WHEN OPENED. WHEN YOU THINK IT WILL STAY OPEN IT WILL FALL DOWN ON YOU. *TR
