Need help '02 Grand Cherokee alarm/start Combo

Yes,  they will more likely work with each other. But you will also need a bypass module for the Key. I always use DEI 455j for factory alarm and doorlocks. and 555C to bypass the key. But there are other companies that carry different modules . Also remember to isolate the key module  when key is inserted into the ignition., to prevent the car fom seeing two keys. Or the or the immobilizer light will beging flashing when the car sees 2 keys. Good luck, not an easy car for a first install.

Notes:

NOTE:  Jeep vehicles that use a gray ignition key have an immobilizer system that needs to be bypassed when remote starting.  Use DEI part number 555C or 555U.  *1 Use ORANGE / black and pink/black at the drivers door lock switch to lock and unlock the drivers door.  Use ORANGE / purple and pink/purple at the passengers door lock switch to lock and unlock all of the other doors.   *2 The dk. blue/pink will flash the hazard lights.  They will flash even with a latch input to the wire.  The parking lights can be activated by using a 1300 ohm resistor to ground on the yellow headlight wire.   *3 Use a 330 ohm resistor to ground for headlight activation.  Use 80 ohms to ground on the same wire to operate both the headlights and parking lights.  *4 There are 4 separate door triggers wire, one for each door.  Use all 4 wires and diode isolate each together.  The drivers door is tan/red at the drivers door lock switch. The passenger door is tan/red at the passengers door lock switch.  The drivers rear door is tan/orange and the passengers rear door is tan / YELLOW at the BCM. WHEN USING A 455J INTERFACE MODULE, IT IS NOT NECESSARY TO USE THE SEPARATE TRIGGER WIRES. USE THE YELLOW WIRE AT THE UNDERDASH LIGHT FOR DOOR TRIGGER.  *5  Factory alarm disarm requires a 463 ohm resistor to ground on the lt.GREEN/ orange wire at the drivers door lock switch, you MUST use a relay.  *6 The 4.7L motor has a separate coil for each cylinder.  Go to any coil and use any wire that is NOT dk. GREEN/ orange.  On the 4.0L motor use any of the tan/stripe wires at the coil pack, or go to one of the fuel injector and use the wire that is NOT dk. GREEN/ orange.  *7 Can also use DEI part number 455J door lock interface control module. This will control door lock, unlock, arm, disarm, dome light supervision and more.

The JDL-PK takes care of both the doorlocks/alarm and bypassing the transponder.
