Does Lumina sedan have rear seat pass thru to trunk ?? if sedan then a pull tab will be in seat upholstery near shelf / by rear window . pull it crawl in with Light Plus friend on outside to hand tools .. IF VAN must remove interior panels to gain access .. Try small thin needle nose pliers to pick broken KEY Piece out of lock 1 ST . if successful spray in Lubricant before trying another key . BUT must be reason lock jammed -- Frozen by weather change or Mechanism Disconnected due to lack of lubrication or worse Plastic Parts used in assembly by Factory .. DRILLING Lock Out will get it Open but new / used parts to repair are now on your shopping list ..

Testimonial: "No, van trunk key didn't breat off in lock. Entire handle and key insert broke off of van back door that raises up if unlocked and handle turned. It only shows inside hard wear where outside handle or knob ( whatever it's referred to) broke off even with door. And when you say inside panel must be removed, you are meaning the cover over back of van up to window, right? Once I take off that , is there something I'm to pull inside around that key entry area? Or do you mean I will have to remove inside lock? If that's the case, it will be unlocked and sitting until I get new lock, like broken one? If that's the case, warmer weather is a sure need. Thanks for input."

Unlock trunk to 98 toyota corrolla

Usually there is a bar between the lock and the latch.
If the lock is broken and you can gain access thru the back seat, you should be able to take the bar out and turn the latch with a screwdriver.

My hood release wire is broken on my 92 chevy lumina van and I was wondering if there was some way to get it open

If you can get under the van and using a flash light look up to the bottom side of the hood. You will see a lever hooked into a rectangular loop. take a pair of plyers and pull on the wire to open or take a piece of round metal and have someone puch down on hood and you can push the hook for the hood

The trunk don't open

This happened to me many times. Usually the little rod that operates the lock falls off because the little plastic clip gets broken that holds it to the lock. There are two solutions. The first is to take out the top of the back seat of your car and reach back to the exposed lock area and open the trunk. If your lock is not exposed, then you may have an internal lock release switch inside the trunk to prevent kids from being trapped inside. If your car has this button, look for it with a flashlight or read your owners manual to get the location. On Mercedes, its a lighted green light, so you can see it in the dark. Just press it and the trunk opens and then you can gain access to the back of the lock to see if the rod came loose.

Trunk will not open

Your latch may be broken go though the trunk though the back seat. Check to see if the latch is broken; or stuck. There is a little hole where all you have to do is use a screwdriver turn clockwise if trunk opens then your latch is either broken or your locking mechanism is stuck. Good luck and hope this helps you.
