Jeep Grand Cherokee Alarm System

1993-1995

I would try reprogramming the Remote Keyless Entry (RKE) transmitters before

looking for anything else. Make sure the batteries in the RKE transmitters are

good and replace them if in doubt. Here's the procedure for programming the

RKE transmitters.

Up to 4 Transmitter Identification Codes (TIC's) can be programmed into the

receiver at any given time.

1. Open the driver's door of the vehicle. Leave it open through the

programming procedure.

2. Move the mechanical door lock lever to the LOCK position.

3. Insert the ignition key and turn it to the RUN position.

4. Turn the ignition to the RUN position. Within 20 seconds, aim a

transmitter at the receiver dome and press the lock button, for at least 5

seconds. Once the receiver accepts the programming code the driver's

door will unlock.

5. Once the first transmitter has been programmed, additional transmitters

(up to 4) may be programmed into the receiver. Within 20 seconds of the

previous transmitter programming, move the mechanical door lock lever

to the Lock position. Aim another transmitter at the receiver dome and

press the LOCK button for at least 5 seconds. The door lock will cycle

again.

6. To lock the programmed codes into the receiver, the ignition must be

turned off and back on within 20 seconds after programming the last

transmitter's code. At that time, all previous codes are erased from the

module.

If the alarm still doesn't work correctly, you probably have a bad Alarm Module.
