How do i disable the factory alarm system - Mountaineer Mercury Cars & Trucks

There isn't one the alarm if factory fitted is integrated into the ecm so to disable the alarm you would need to disable the engine control module

Best to hire an experienced alarm installer to disable your factory alarm.

If it is a factory alarm system you can't..

The alarm system is integrated into the vehicle electronics, you can't completely bypass it. You don't need a remote to have it work right and not go off, you have a problem with the system like a door sensor.

The factory alarm is tied into your ignition switch. Most newer vehicles have an anti start system incorporated into this in case it is broken into. The alarm will shut the system down and will not allow the vehicle to start. Look under the dash under the driver side and see if you can locate a small box. Should have a serial number barcode on it. If so it has a factory alarm.

the factory alarm doesn't stop the fuel system it only cuts the starter your problem lies somewhere else

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.

well thats an interesting idea but by bypassing the alarm your car will not usualy start it is a safety feature that is built in to all chrysler autos it will disable the starter coil door locks windows and half the electrical systm as a safety feature and anti theft feature

for a factory alarm the only way is to lock/unlock doors(with key) unless some one knows how to disable the alarm altogether. if alarm is not factory just find the box and remove alarm system (you may need to reconnect some wires if it has starter disable as a feature)

1st the system alarm is intagrated into the engine control electronics, it can not be disabled without poss damage to ther systems and controls, 2nd the most common cause of your issue is the sensor in the ignition lock cylinder being defective, this is the most common issue on all GM anti-theft systems.
