The key problem could be a worn out key that is not disengaging the tumblers in the ignition switch or tumblers that are sticking(squirt a little wd40 in the ignition cylinder and move the key in and out a couple of times) inside the switch. Make sure the shifter is fully in park.

SOURCE: Ignition Key Doesn't Turn Sometimes in 2001 Jeep Grand Cherokee

This is a tumbler problem. If you want to fix it yourself, you need to disassemble the the column untill you get to the lock cylinder and figure out how to remove it and remove the tumblers. This will allow many different keys to start the car however. Your other option is to replace the lock cylinder with a new one and new keys. That is up to you, but you should do something before the keys quit working all together.

SOURCE: 1994 Grand Cherokee Jeep wont start

It is likely one of your battery cables loose. Same thing just happened to me today. What you need to do is first lock the doors, and close them. Then you need to disconnect, and reconnect the battery cable, then if the security lights still blink you must use your key to unlock the door, then it should stop blinking, and start just fine.

    • 1

      Unlock all of the Jeepicon1.png Grand Cherokee's doors and open the driver's side door. Keeping the door open, lock it using the manual lock on the door itself.

    • 2

      Put the manual key into the ignition and switch it to the "On" or "Run" position, whichever applicable, without starting the engine.

    • 3

      Point the remote at the receiver (located by the little bulb on the caricon1.png ceiling) and hold down the "Lock" button for up to 5 seconds.

    • 4

      When the driver's side door unlocks, you know the remote has been programmed correctly. If you are only programming one remote, jump to the next step. If not, manually re-lock the driver's side door and repeat steps 5 and 6 using each remote you would like to program and then continue.

    • 5

      Turn the key to the "Off" position and turn the ignition on immediately. This must be done within 20 seconds of programming the last remote. You're finished!

How do I know if my ignition switch is bad on my 1995 jeep grand cherokee lerado 5.2 liter


The ignition switch does not usually go bad on Grand Cherokees but the ignition key cylinder does and it usually just stop turning, stuck in place. Key cylinder can be removed by taking the steering wheel off to access the little clip that's holding the key cylinder in place, inside the steering column.

Steering wheel locked and key will not turn 2000 jeep grand cherokee


First thing you need to try is wiggling the steering wheel back and worth while turning the key to try and unlock the steering column. If the key is worn out it may not turn well in the ignition. Another thing is to lubricate the ignition cylinder. If nothing works, it maybe the ignition cylinder tumbler is worn out and needs to be replaced.
