I had this problem in my 1998 olds 88ls pretty much the same car. Open the glove box there should be a little switch in there that say trunk lock/unlock. make sure its switch to the unlock side. the idea for the switch is so you can put valuables in the trunk flip that switch to lock then lock the glove box and people cant get your trunk open and steel your stuf.

Just started today I cant get the trunk open. The key doesn't seem to turn all the way and the trunk release leaver located next to driver seat also will not open it.

You may have jammed some material into the latch. A rag or cloth or even paper can cause sudden binding on the latch to the point it won't open. Find a partner to assist you to press down firmly onto the trunk lid to try to relieve excess pressure on that latch, while the other person tries to turn the key and/ or pull that lever.

If that does not work, try the opposite force (ie. pulling upward on the trunk lid) and doing the same. If bad enough, this may take a while, with effort. But be careful NOT to break off your key in the lock cylinder.

If this fails, try accessing the trunk from the rear seat (even removing it). You may even see the culprit from there as the material will be stuck, requiring firm pulling to get it out of that latch.

If, when you finally do get the trunk open, if it turns out it was NOT an obstruction, your lock mechanism may just be bound up. To free it spray liberally with penetrating oil such as PB Blaster. Allow to soak a bit, then repeatedly rotate the lock with the key. It will soon work like new!

The trunk will not close

Try a little grease or PB Blaster, or WD40 on the latch itself...could be the latch is stuck in the open position. Has there been a collision around the trunk latch? If so, a re-alignment of the latch and catch may be necessary. Hope this helps.

Cant get trunk open on 1998 cadillac sts ,i tried the botton and key.neither which work,

Try spraying WD40 or PB Blaster into trunk lock cylinder. Let it sit for a while to work things loose, then keep wiggling the key while you try turning it gently. Work the key in and out of the cylinder to try and free up the tumblers. As for the electrical switch, check your owner's manual to see if there's a "Valet" switch or some other lockout located somewhere else in the car.

There is no sound when I press my trunk button on my vw keys. Also the trunk is seized. I cannot turn the key to open the trunk. I would like to fix the lock. How do i do it?

the motor for the lock actuator is most likely seized. you will need to try spraying PB blaster (tm) into the lock cylinder and letting it sit for a few minutes and then try the key (I wouldn't force it) if that does not work you need to get into the trunk and disengage the lock from the actuator. and then the key should move the lock freely...

Trunk wont open and the back seat wont fold down on our kia optim

By switching the lever you locked the inside trunk release, you will need to put lever back. as far as the trunk you may need to remove the rear seat, pop lower part out and then remove the bolts to the top half of the seat then try to reach the lever so it will open from the inside. i've found that many of these cars with the pop lever inside have sticking trunk locks from not being used, what you do first is spary lock good,with wd40 or pb blaster then slide key in and out and try to turn this may take a whhile but it works then tumbler will free up, you just have to keep spraying inside lock and working the key.

Vw polo 2003. Fuel filler flap won't release when central locking opened. Is there a manual override?

There probably is. My 99 Audi A4 has a release cable in the trunk. It's behind the trunk lining above the filler neck. Mine's red for easy identification - just pull it and it pops the gas door. While it's open, spray the lock with some white lithium grease or PB Blaster, and work it in. It may be that the latch is just sticky and those should clear up its operation.

Door Ajar light and interior lights always on.

the best lube to use for these latch assembleys is PB BLASTER available at your local parts store. spray each latch really good one at a time, then open and close door 10 to 15 times. trust me PB BLASTER takes care of this 90% of the time
