How can i openmy trunk? Key wont work.. (old) '91 Pontiac...

[*Ash*<3]

...Sunbird.? I have a 1991 Pontiac Sunbird.. I cant get my trunk open.. like it used to just be hard and the key would have to be a certain way.. but now i just cant get it opened at all.. no one can.. its been several months since weve had it opened.. i need help! i got some important things in there i need for next week.. the only problem is.. i need my trunk to be able to actually shut when im done.. i think i might need a new lock? do you think so? how hard is that to do? and how expensive? how time consuming? teenage girl.. knowsnothing about cars..

Could be the key, the cylinder, or the latch itself. Costs would run between a dollar fifty to over 500 dollars. I would take it to a reputable repair facility and have a professional look at it for you and get an estimate.

start by spraying some wd-40 in the key hole and running the key in and out of it a few times....hopefully it is just a stuck tunbler and that will free it up.......if it doesn't work get a locksmith....they can fix you right up in a hurry!!! good luck!!!!

PS: it will NOT cost $500......150 at most!!!!! I don't know what shop Will uses but he is getting robbed if he pays 500 for a trunk latch on a sunbird LOL!!!!!

if your low on money you can get in from the rear seats there should be two triggers above each seat

You can probably pull out the back seat. To remove the seat push front seats all the way foreward, - get in (rear car floor)- facing rear and put knees against bottom cushion as low as you can, - the push to rear, -- while lifting seat upwards (near your knees) ... There is a "loop on each side about a foot or so apart from each other, - there are two prongs that catch under these loops to hold seat down... once you have pushed back far enough and lifted to get these prongs unhooked the seat will then lift out! You will then see two bolts that secure the rear cushion (vetical one)-- they are about 18" from ends of seat at bottom,-- when these screws are out, you can then lift the seat out vertically for about 2" and the little prongs that hold them to the rear tray, - will unhook, and you can now set that seat outside also! Now you can push out the "divider cover- which is a piece of cardboard! If you are small enough you might be able to crawl between the metal web piecs between trunk and rear seart area.. If not you can probably get a bunch of extensions and a socket and remove the bolts that hold the trunk lock in place- which will then let the trunk be lifted with lock,-latch still attached!..Once apart you can manually open the latch and remove latch plate and put it back in place! The lock is usually held in place with a "horseshoe" shaped metal spring-clip. Remove the clip, should have the flange on clip (facing)to drivers side of trunk lid, - hook it with screwdriver and pop it sideways (and remove)- and the lock should pull out pretty easily, - check to see if it has any attaching points on end where it lifts the latch! With the lock out, you should be able to use a screwdriver to open again till you get lock fixed or a new one!--- Check with screwdriver to see how it "matches up" while lid open and you can see how it fits!

If you have a friend with a GM car about the same vintage, you could look inside his trunk and see where the bolts for the mechanism are, - then you won't have to hunt so hard with flashlight to see where they are (when you get to yours)! This body style was in production for quite a while, and most GM cars are pretty much the same in this area!
