I had the same problem and tried to tap the area where the key goes into the steering column. Be very carefull not to apply too much impact. The plastic? silver piece that is outside the steering colum (and gives extra leverage to turn the key) can break off from the cylinder. The result is a hole in the steering column with just the base ignition key cylinder visible. If the jam is that piece of silver collar, it will free up the cylinder to turn, but you'll be turning the cylinder using just the key, so be carefull not to end up with a broken key inside the cylinder...

Ignition switch for 2000 jeep grand cherokee is stuck


I'm going to answer this question since I don't know how the security system would affect the lock.
If you can get the key out of the lock, you may want to spray some WD40 or other lube in the slot where the key goes.
If that does not help, you should be able to drop the cover from under the steering wheel and disconnect the switch from the lock cylinder.
If the lock is still stuck, it may have damaged tumblers or something may be jammed with the shifter and steering wheel lock.

Don't know how to get old ignition switch out to put new one in.


How to remove an ignition cylinder for repair or replacement if your Grand Cherokee's ignition won't turn. This is due to the tumblers failing. Key must be tuned to the on position. Then you press in the lock tab to release it so you can repair yourself or more likely, bring it to a locksmith to have the tumblers replaced. This can be done to match the existing key. Obviously, you'll have to get it to turn to do this. Usually a good dose of WD40 and tapping on the head of the key (straight in) will free it up temporarily. This would be the view from underneath the column after removing the two shroud halves.

Ignition on my 2004 jeep grand Cherokee is locked, how do I unlock the ignition? Keys goes in ignition, door chim works when key is in ignition. But the key won't turn it's stuck.


tap the ignition lock cylinder with the plastic end of a scrwedriver (with the key removed). then insert the key and try to start. Try this several times. If you get it to turn immediately replace the igntion lock cylinder. The cylinder needs to be in the on position in order for the lock button to be depressed so that the cylinder can be removed from the housing.

If you still can't get it to turn than you will have to drill out the lock button in order to get the old lock cylinder out. I wouldn't recommend doing this unless you have some experience and understand what you are doing.

The lock button can be accessed by removing the lower steering column cover.

1999 jeep cherokee 6 cylinder engine light


1.Plugs
2. Vacuum leak
3. Injector fault
4. High or low fuel pressure.
Thats the list of things to check.
This is a #3 cylinder misfire.
There is also TSB about #3 injector needing added heat protection. This could definitely be the cause. I start at plugs and go from there.
Hope this helps.
Thank you,

I have a 1999 Jeep Grand Cherokee. The vehicle


sounds like the key is either worn down to where the ridges in the key wont push the tumblers inside the key lock cylinder into their proper place to move the cylinder into the starting position. Or your steering colum is locked and the wheel is moving freely as if it were not. So your solution would be to either have an expert look at it (estimated cost: 200$ low/400$high) or you can attempt to fix it yourself.
should you choose the "I'll fix it myself" method....try getting a new key made at a hardware store since keys wearout over time (ie:10years of turning that old key), this may solve the problem right away if the ridges are just worn on the key. Or the hard way, you need to get a phillips screwdriver and some jewelers tools and an 8mm or 10mm wrench/rachet+socket to disconnect the battery, then underneath the steering colum just under the ignition is a hole in the colum shroud/cover, from there you can disconnect the ignition key lock cylinder (the thing you put your key into). once you've removed the cylinder from the steering colum you should test your key again to see if you can turn the cylinder outside of the colum if you cannot then buy a new ignition key lock cylinder for about 15$-30$...problems solved.

How to replace an ignition cylinder lock on a 1999 jeep grand cherokee


Hi,

1) Disconnect and isolate Negative (Ground) battery terminal
2) Wait full 2mins for Airbag system capacitors to discharge (must disable airbag before working near steering column)
3) Insert key and turn to ON position (not start)
4) Release & remove cylinder barrel by pressing the release with a suitable tool (access through hole in the lower shroud)
5) Withdraw cylinder barrel from shroud and disconnect wiring loom from cylinder.

Installation of new barrel is the reverse of above.

NB: YOU MUST ALWAYS DISABLE THE AIRBAG FIRST !

Hope this helps...

Cheers,

Roll the key back to the lock position and push the roll pin in. When you go back together, rolling the key forward pushes the roll pin back out to lock it in place.
