Question about Jeep Cherokee

Open Question

How do you disable an alarm system for a 1991 Jeep Cherokee Laredo. We lost the keys, and took advice from an auto mechanic. He suggested that we drill the ignition but when we did, we drilled too far into and damaged the switch. We tried hot wiring but everytime we get a jump, the security disables the starter. We'll hear it try to start but no luck. Is there anyway we can either A)bypass the alarm system or B)disable the alarm system so we can get it up and running?

Solution 1
1) Remove the driver door panel 2) Remove the lock 3) Remove the switch from the back of the lock 4) Pull the switch cord assembly to the bottom of the door cavity 5) Unplug and remove the switch assembly from the car 6) Either (a) short the female end of the plug, or (b) ground the striped wire to the car door.

Solution 2
Normally, you would insert the key in the drivers door, turn left, then right to disarm and reset it. If yours is malfunctioning, you can disable it for good by doing the following:

The FACTORY ALARM DISARM WIRE IS purple/yellow |-| in the driver kick panel area, at the black plug.
Once Located, splice into this wire with a simular guage wire, and put it to a solid chassis ground. This terminates the alarm functions entirely.

Solution 3
Go to the passenger side door and lock/unlock 2 or 3 times to deactivate the alarm switch in the door latch. If battery is weak/low it wont solve problem, must replace battery.also check for broken hood pin switch($5.00) as they are likely to be broken on a 94 veh. and when failed will cause security system to activate causing security light on dash and no start condition/lights flashing etc

SOURCE: Can you disable car alarm in 1991 Acura Legend by

If it's a cheap aftermarket alarm, check for a red wire coming off the hot side of your battery with an inline fuse. If it's not, try to locate the alarm "computer" under the driver's side dash or nearby your fuse panel. You'll find a black box with a wiring diagram glued to the side, normally strapped to a wiring harness or other fixed element. If this is the type of alarm you have, you'll need to trace each wire coming from the alarm computer and unclip each fastener that's clipped to your vehicle's factory wiring. The trouble with these types of alarms is that they can get power from a number of sources (stereo, interior lights, etc.). Good luck with this one!

This means it is the solenoid. But usually on those the starter and solenoid are one unit. They can be purchased individually, but it is usually almost as expensive as replacing the whole unit.

My 1991 jeep alarm goes off whenever the key is turned in any of it's doors. How can I disable the entire alarm system? Thanks


On a 91 Cherokee, grounding the ORANGE/GREEN wire from the drivers door lock sensor will permanently disable the OEM alarm. Do NOT try other methods as it will cause the system to lock down. If that happens, nothing short of a dealer reset or completely removing the electronic control system will allow you to start it.
