Resetting alarm on 2001 mercury cougar

Brother is trying to change the battery in his 2001 mercury cougar. The security alarm keeps going off and he can not start the car. Have tried to reset using the key in the locks, that seems to not work. Any other way to do this?

SOURCE: 2000 Mercury Cougar Power door locks do not work on either door

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.

Try turning the ignition to on and wait about 10 minutes. Assuming it has been flashing, it will stop when it is reset. This problem will most likely occur again in the future.

How do I reprogram the car alarm system of a 2001 mercury cougar? the car alarm goes off randomly.


I once had a new car do the same thing. It was a short in the battery. The alarm system was thinking someone was tampering with the power supply.

Where is the fuse for the alarm located on a 1999 mercury cougar


There isn't one. The alarm is hot at all times. Direct battery power. You will need an electrical schematic to check for power to the security module.

I have a 2001 mercury cougar, the headlights were left on last night and the battery died. So when jumper cables were connected to the battery the alarm started to go off. The fuse was removed and put back...


You can probably pull the horn relay to kill the horn while you are working on the problem.
With the battery connected to a jumper, try locking and unlocking the driver's door with the key. If that works, make sure the battery gets charged before you unhook the jumper cables to keep the computer memory alive.

2001 mercury cougar can't get car to start alarm light lit and steady what do I do


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.
