How do you disable the security system on a 1991 Jeep Cherokee?

Answer 1

take your key and turn the lock on the drivers side door, turn till the security light goes off, hold for 3 to 4 seconds I get out of the car, stick the key in either door lock and unlock the door, then it should work. lock all your doors. go to the back lift gate and turn the key. sometimes the lock in the lift gate gets stuck and sets off the security system, exspecially after the battery died or was disconnected. I was just having the same problem after having it towed for 100.00 and two hours of taking apart the dash all it took was to lock the door open the hatch 1st with the key then unlock the drivers door. this worked for me i hope it works for you.

Answer 2

To reset the security system

1. open the hood,
2. disconnect the black battery cable,
3. reconnect it,
4. turn your key in the driver door twice,
5. hold the key turned for 2-3 seconds on the second turn.

That should do it. i have a short in my security system and i have to constantly reset it like that. You will have to set all of your clocks after doing this though.

If turning the key in the door does not work, the switches in the door have fallen off of the key cylinder.

If that doesn't work hold your foot on the brake, put the gear in neutral, and turn the key again to start it. That's what I have to do to mine.

Did you shut off the security system by using the key or the remote? The engine will not run as long as the security is triggered.
