Door locks won't unlock

Searched around, only found electric door lock problems.

My 96 cherokee's door locks will move. The key turns, and the inside switch moves. However the door doesnt actually unlock. This only happens if you press the button in while its locked.

Its finally done it so I can't get it unlocked (so i can strip the door and clean the parts)

How can I unlock / open the door?

I have this issues from time to time. Put the key into the door, turn it left and right until you can almost hear the little latch move back into place. Then push the button and pull the door open. Sometimes I have to work mine from the inside to get it goin'. Move the little switch back and fourth.

Found that if you spill some WD-40 into the lock it helps it out for a while.

If you get it open and open up your door, post some pictures here and let me know the step by step. I'll prolly end up doin' it to mine as well.

Those door locks suck.

After an hour of tinkering, I found the problem. Rust and corrosion easily contaminates the locking mechanism inside the door. When the door is locked, and you press the button/pull the handle, the moving part that pulls the latch gets stuck. This is because of all the rust.

What you have to do is disassemble the door. When you pull on the metal arm for the handle, you see a small piece that rotates down near the lock. Where that piece hits, is a little piece of metal on the underside of the mechanism. If your door locks are stuck, pull this piece of metal down, which will free the button/lever. Now you will be able to actuate the locks.

To prevent this from happening, you must keep your locks healthy. And the keep anything healthy, I mean excersise!

*NOTE* DO NOT REASSEMBLE YOUR DOOR UNTIL IT IS FULLY WORKING**
This means you are able to push the button on the door with it locked, and still be able to unlock it afterwards.

With the door unlocked, push the button and pull the lever as many times as you possibly can. After you have done that, lock the door, and push the button and pull the lever a few times. Now try to unlock the door. If done correctly it should unlock the door just fine.

Use your door locks often, and use the handles as well. This wil keep your locks from sticking.

I would have had pictures, but its impossible to get any as the mechanism is inside the door.

Let me know if it comes back in a few weeks time. The WD40 deal worked and any combination of button pushing worked for a while. I think i'm about due for another session with that stuff. I had a hard time gettin' out of 'er the other day.
