ARLENE VAN PATTEN

MEMBER
LINCOLN TOWN CAR

I have a 1992 lincoln towncar, v8, with 67000 miles, it has a factory installed alarm system. When we park the car after about 5 - 15 minutes the alarm will go off -flashing lights and horn. It will continue to go off as long as the doors are locked. If we leave the car unlocked the alarm will never go off. We took it to a dealer who said there was no way to disconnect the alarm. Is there a way to disable the alarm system, so we are able to lock all of the doors for security reasons?.

When you turn the key to run position the led should be off if not the lock sensor for the key is NG or the cicuit is shorted.
Activate the door lock switch 5 times in ten seconds
and count the led flashes. If it flases only one time the door disarm is OK, any more than once and there is trouble. If your not good with testing anti-theft and other ciciuts. Take it for service!
When you want to lock the car try doing it from outside with the keypad, press buttons 7 and 9 at the same time. It sounds to me like the key sensor tho.
