How do you switch out the tumbler in a key switch on a 87 Jeep Wrangler?

The most common reasons a Jeep Wrangler key won't turn are a binding steering column/lock, an ignition switch issue, or a problem with the ignition key.

Could be a bad ignition switch or could be the shifter lock out.

If the key will not turn past the on position, and it turns to all other positions then you need to replace your ignition switch, if it doesn't turn anywhere but the on position then you need to replace your tumbler. For the ignition switch you will need a mechanic, for the tumbler you will need a locksmith.

have u ck out the ignition switch [not the key & tumblers],, or the neutral safety switch to see if u have power ,,also seen broken wire at solenoid on starter too,,hope it helped,,

Before you start tearing into this repair, let me ask a couple of questions.
Do you want to replace the ignition tumbler assembly because you lost your ignition key, or because it is broken or worn out ?
If you lost your key I believe Chrysler can help make you a new one, you will have to get your VIN number and call your Chrysler dealer.
Please let me know

dropped tumbler in lock

could be, try moving wheel right to left while trying to turn the key, steering wheel may have tension on lock, if that doesnt work try another key if still nothing then replace switch, remove cover around switch, then use a pick to push in lock pin must trun key to get pin to go in you will see little hole on housing were lock is that where you install pick and push while truning key, got to get key to turn once more to get that lock out.

try a spare key, or push key into lock while turning
it is the tip [pointy end] of the key that releases the switch tumbler lock allowing it to turn. keys & switches wear out, a 'heavy' key ring especially wears the switch.

You have to go to the Jeep dealer and they can take it apart and install new brass tumblers to match the key.

I have had this same problem on 4 of my Jeeps. A locksmith provided me with two answers.
This key thing happens to me at least once a week.
It is a common problem with Jeeps. 1998 Wrangler, 2007 Cherokee and two 2000 Cherokees all had the issue.


1. Replace the tumbler assembly. $150. USD (Not!)
2. Place the key in the ignition, smartly impact the key on the **** end, end that is sticking out of the ignition. (Harder is not better) strike straight on as to not break the key off. 4 or 5 strikes should fix the problem every time.

FYI - flooding the switch with WD-40 will not fix the issue, it is a tumbler problem.
