2001 MERCURY COUGAR DOOR AJAR ALARM WONT QUIT BINGING EVERYTHINGS BEEN CLEANED AND WONT STOP PLEASE HELP

does it have a key on the alarm module to turn it off ?

It sounds like you have an aftermarket alarm system that has malfunction. Contact the manufacturer of the alarm for the reset procedure.

If it is an aftermarket alarm then you adjust the sensitivity it under the dash youll see a little square box turn to the right and you decrease sensitivity or left to increase lets say a feather fall on it and the alwrm goes off. Now if it is factory alarm they have the access for it and they reprogram the alarm sensitivity.

Try opening and shutting the hood,and the doors,and the trunk,and activate the alarm,and then disarm the alarm,if this does not work,then the alarm system will have to be replaced,the receiver.

check each door jamb switch. the little button that contacts the door usually near the bottom of the car body. manually push each one in and out to see if the light goes out.

sounds like your alarm is preventing the car from starting.

you can disconnect your negative battery cable, and wait about 10 minutes. put the key in the ignition and turn it to the ON position, but NOT to the START position. reconnet the battery cable CAREFULLY with the key ON, and the driver's side door OPEN. your alarm should "chirp" a few times, while reconnecting the battery. afterwards, try to start the car when the battery is tightly connected.

if the car still refuses to start, use the "panic" feature on your remote, to intentionally set off your alarm, and then turn it back off, to make sure it stops properly.

if this does not work, remove the fuse for your alarm, and try to start the car again without the fuse in place.....otherwise replace the fise and remove the pwoer connector from your alarm.

your actual alarm should be behind the trim plate, on the bottom side of your dash, above your gas and brake pedals....then try to start the car AGAIN....

if none of this works, then your alarm is defective and needs to be serviced be the installer, or manufacturer. also, calling the manufacturer will help too, as they have "reset and disable" features that can literally "bypass" your alarm.

get locking gas cap!!!!

Power door locks are on the same fuse as the alarm system. The fuse is located in the passenger compartment fuse panel under the steering wheel. There is a pull down lever that will release the fuse box. The fuse for the alarm system/locking system is #25. Yellow color and a 20 ampere rating.

there is a switch in each door that senses the door is open, it is called the door ajar/courtesy light switch (imagine that), they stick and have this problem, replace it.

Alarm imobiliser faulty ..
