Jeep Grand Cherokee Imobilizer Reset

Question: 2002 grand Cherokee jeep. Wrong key put in tried number of times to start with right key immobilizer only lets the car run for few seconds red light with line through key comes on can dealer reprogram or what parts do I need.


Yes, you will need to get it to the dealer to have them reprogram the system. Putting in the wrong key has set the theft system. You could try to disconnect the battery for a few minutes, reconnect it, turn the ignition key to the ON position- not crank postions. Leave the key on for 10 minutes. Then shut off the key for 5 seconds. Now try to start the truck
