The owners manual will tell you what you need to do. Did you try to put the key in the drivers side door and lock and unlock it? If that doesn't work try doing the same thing to the passenger side door.

Horn BEEEEEPS every 5 mins.


Besides the switch on the steering wheel being pushed to control the horns , the BCM - body control module can activate the horns as well .
The horn system consists of the following components:
• HORN fuse
• Horn relay
• Horn slip ring
• Horn switch
• Horn assembly
• Body Control Module (BCM)
System Operation
The vehicle horn system is activated under the following conditions:
• The horn switch is depressed.
• The body control module (BCM) commands the horns on. The BCM commands the horns on under any of the following conditions:
- When the panic button is depressed on the remote control door lock transmitter. For further information refer to Keyless Entry System Description and Operation .
- When the keyless entry system is used to lock the vehicle, a horn chirp may sound to notify the driver that the vehicle has been locked. The notification feature may be enabled or disabled through personalization. For further information refer to Keyless Entry System Description and Operation .
Circuit Operation
Battery positive voltage is applied at all times to the horn relay coil and the horn relay switch. Pressing the horn switch applies ground to the horn relay control circuit. The body control module (BCM) may also apply ground to the horn relay control circuit as described above. When the horn relay control circuit is grounded, the horn relay is energized and battery positive voltage is applied to the horns through the horn control circuit. The horns sound as long as ground is applied to the horn relay control circuit

The BCM is receiving an erroneous signal from somewhere , keyless entry maybe. Hooking up a professional type scan tool to view inputs to the BCM would be the first diagnostic step I would do at the dealer .

Diagnose keyless entry system of 1997 Cherokee


Before replacing any Relay. Try disconnecting the negative side of the battery for at least 2-minutes to de-energize the security system, re-setting itself. The reconnect the battery and try your security (and options) system again.
The only other big question that you will have to know: is this a factory installed security system or an aftermarket security system? This makes a difference in security systems, relays etc.

Keyless entry blinks dome light and does nothing else


The remote is fine - your problem is the lock actuators in the doors. They're a bit of a pain to replace - so, you may want to have a professional do it.

Lights stop blinking & horn doesn't beep when I lock the car


Press and hold for 2 seconds the LOCK AND UNLOCK buttons on your "keyless entry" keypad. The hazard lights will then blink 3 times and the horn will sound once- you are now good to go.;

Engine dies at idle, was slow to start


Two things that I would look at:

1.) The spark plugs should be changed at this mileage

2.) She may be having the beginnings of an Idle Control Valve ("IAC") failure.

The security LED blinking is normal

The horn issue may be a weak battery on the keyless entry remote transmitter
