The security module is located in the dash behind the glove compartment. You cannot disconnect the security module without bypassing the starter wire. The system disarms by unlocking the front doors or tailgate with the key or using the remote key fob. The switches on the door latches are notorious for going bad on the grand cherokees. These switches are inside the doors attached to the lock cylinders and cost about 40 bucks at the chrysler dealership. You can also get a replacement remote fob on ebay but they are around 50 bucks and you will need the owners manual for the Jeep to program it.

    The factory security system on the 1994 Grand cherokee certainly can be disarmed permanently, but you have to possess some electrical, under-dash knowledge. There is a purple wire(with a yellow stripe), located on the Driver's Kick Panel, in a Black Connector. This wire has to be connected to the vehicles body ground, to put the factory alarm out of commission...permanently. I install remote start systems and this is the wire that is used to disarm the factory security, in the 94 Grand Cherokee, to allow for a remote start. I have also manually grounded this wire on a few jeeps, with the same problem as you're having now and it has worked perfectly. Good luck.

I have an '09 toyota camry and the navigation system won't work, tried to hard start the system by disconnecting the battery but it still won't work. Does anyone know how to fix this?


I think you will need to access the Nav System with a professional
scanner or scan tool & then use manufacture trouble charts, to even know what the system is supposed to do, & how to diagnose it

Hopefully a repair shop, if they want the job,otherwise blow out
your wallet at a dealer

Alarm system wont disengage


Disconnect the battery.
Check the wiring (especially under the dash on drivers side fire wall) for shorts, disconnections, or loose or open circuits.
If no wiring problems are evident re-connect the battery.
If the alarm immediately starts resounding then you may have a problem with the security (box) itself that may have to be replaced.

Disengaged the security system however now when I go to start it it blinks security and shuts off but only when I go to start when i turn off the ignition it stops blinking. Its as if it is still...


The security system is connected with the ECU and ABS module. You can't disengage the system, if this is the OEM System. Rebuilt it and your Granny will run as long as you've fuel in your tank.

1990 dodge dynasty 3.3 engine starts fine but a second later dies changed gas filter and fuel pump and regulator still don't stay started.


Same thing happened to my '89 Dynasty. Turns out the security system was engaged and this stops the motor from running; therefore. a thief cannot drive away with the car! The system is set by using the power locks or an autolock fob, but not by locking manually. Disconnecting the battery will also engage the security system. To disengage, close the driver or passenger (front) door and turn the key in the lock.

Security System has locked. Car will not start.


Try locking and unlocking the car with the key and not the remote. Sometimes this will disengage the alarm.
