4Runner alarm will not disable

Answer 1

The Toyota 4runner factory alarm system is quite difficult to disable since it is part of the computer and wiring of the general electrical system that operates the electric locks, horn and ignition. Frequently, the alarm does not work right: You may experience the following: The alarm activates every time you merely unlock the car, and will not turn off until you put the key in the ignition. Many owners have disabled the horn as a simple method. Your best bet is that you will have to go to the dealer to attempt to disable the alarm. Bear in mind, when the alarm does not work right is is because one of the door lock alarm wires has been removed or disabled. If one of the alarm wires to any of the door locks is merely cut or is broken, the alarm system will not work right. This happens alot when you have to replace a door due to an accident, and the auto body shop does not line up all of the wires. This is not an easy thing to fix, even to try to "rig" it in your backyard. Becuase you got to find the door that has the bad alarm wire, and then take it apart to find the bad wire. The most notorious culprit is the rear door hatch. If you can locate the alarm wire to the rear door hatch (or the door you suspect has the problem) and either reattach it or add a wire and somehow connect the "problem" wire to another door that has the wire and is working correctly. Again, these alarm wires cannot be merely "cut" and go nowwhere. They must complete a circuit, and if the circuit is not complete the whole alarm system malfunctions. Thus--you can try hooking the "problem" alarm wire ---to an alarm wire to a door that the lock is working properly.
