Looking for some help. My grandfather just bought a ’99 Taurus Wagon with 36k (believe it or not). The car has an alarm system that arms itself as soon as you get out and close the door. He likes to leave his car unlocked as he uses it for work and he is constantly in and out of it. It has already gone off a bunch of times, and he is getting tired of it… Since the car didn’t come with an owner’s manual, I was wondering if someone can tell me how to disable the alarm. The car does have keyless entry and it is a FORD remote.

Thanks in advance!
