jeepbastard This is my old actuator, the thing fell apart and broken in multiple places (the bottom spring wasnt even in the right place anymore.

AjRagno Good to hear you got it fixed so you could drive home.


The ignition may feel wonky because 2 of 3 parts are 22 years old. If you're worried, since you now know how, you can recheck when more convenient.

jeepbastard Aww yeah! thanks dude! she fired up!
My key and the lock cyclinder is still a little wonky - like it doesnt feel as tight as she used to be - not sure why, but shes back in action!

AjRagno You're just about there. It's the ignition switch that controls what receives power. When you push it onto the actuator, just make sure everything is lined up. If it feels like it's not going on, you may just need to rotate the key slightly one way or the other. If it still does not line up, you may need to turn the ignition switch to RUN. Just make sure the battery is disconnected.

That white plastic tip at the end of the actuator is for the key in ignition sense that causes the chime.

If you have an automatic transmission, make sure you don't lose that little tab in the shift interlock. It's referenced at around 8:15 minutes in the video.

Did you reinstall the ignition switch? In this photo, it's not connected to the actuator? The key turns the cylinder, which tuns the actuator, and the actuator turns the ignition switch.

AjRagno Were the actuator pins broken?

jeepbastard i did get it in!

But now i have no light on dash and its not cranking. Something is still off. (there is power at headlights and accessories.)

AjRagno In the video, around 5:00 minutes, it looks like he had the same issue and said he had to make sure the ignition cylinder was in the ON position. If you remove the ignition cylinder, rotate until the key can be removed, then reinsert the key and rotate one click right.

jeepbastard That video was super helpful, but for some reason the lock cylinder wont go back into the hole at the bottom as seen in the photo. Not sure if Im not pushing it hard enough or something else is wrong. I tried two different lock cyclinders and i cant get either to lock back in properly.

Notsmartenuf If it is either the pot metal or the plastic, look at the many options on ebay/Amazon. Think a lot of Liberty models have them as well.
One of the easiest ignitions to pop & go for theives. They tried my 98 TJ twice, but didn't look for or find my killswitch either time

AjRagno I can't really tell if there is an issue with the lock cylinder. More typically, the pot metal pins on the ignition actuator fail and no longer engage the ignition switch.

To access the actuator, you need a T-10 security bit (or you can break off the security tabs with a nail or a punch).

Since you don't have a sentry key, you could put a screw driver into the actuator and see if it turns the ignition switch. If that doesn't work, and if you don't have another vehicle to get to the parts store, you can remove the ignition switch or the actuator and use a screw driver to turn the ignition switch to start.

Jeep TJ wont start: Lock Cyclinder turns but doesnt quite feel right.

Jumped in the jeep and it wouldn't turn on. No lights on the dash - although there is power in the battery (accessories work directly wired to battery).

The key turns but you can tell its gamey. Its not tight enough to trigger anything. Any work around on this? Or do i just need to find a new Lock Cylinder to replace it? Is it unfixable without a new one?
