2000 Mercury Cougar alarm system, how and where do I disable it?

Disconnect the battery cables and wait 5 minutes then reconnect them if your alarm sounds use your key fob to stop it then you should be okay also the key you have maybe has a battery in it and it's dead if it was an aftermarket key programmed at Lowe's or home depot look at the key if you see little tabs on the bottom there's a battery in there

shorted out something or line check alternator - battery and harness

You can disengage alarm with a remote if you have one otherwise, close bonnet, all doors and lock the car by turning key completely to the left and right few times and do the same to unlock. This will dead lock and unlock the car. When you hookup the battery make sure you connect red wire first and then the black one.

Remove it completely or get a new one,alot of times they go bad believe me I have remove many it messes with your system on your car sometimes prevents you from starting vehicle.

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.

If you have the factory alarm system, you can put your key into either door and lock and unlock the door, that signals the computer to deativate the alarm. If you have an aftermarket alarm system installed, it will have to be removed and the wiring that the alarm ties into must be restored to factory design.

You need to reset the alarm system.That can be done with the remote entry key fob or by locking then unlocking the drivers door with the ignition key with all doors closed.This is for a factory alarm system.Also check the inertia switch,should be in the trunk,on the side with a push button top.Push button.If already down its not tripped.

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.

sound like alternator quit charging the battery.check battery voltage.it should be 12.5 volts.if not charge the battery.remove and have alternator tested at auto zone or advance auto parts.dont forget to turn off radio when disconnect negative battery cable.

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.
