How do I open the trunk of my 97 grand am when key wont turn it

Remove the back seats and crawl through to unlatvch the trunk.

Valet Key ? 0nly does the drivers door & ignition

if it wont open at all ! remove back seat and get inside trunk to release the lid.

It locks the lever that opens the trunk of the car so you wont be able to use that lever to open the trunk from inside the vehicle. The master key should fit in it. You will still be able to open the truck with the key on the outside right at the trunk with the key even if you have the lever locked. It's a security thing. I hope this helps.

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.

yes a screwdriver or pliers depending if you can see the lever from where the key fits from .just turn it or open the lock itself

Hold the driver's power door lock button to the left until you hear the trunk release pop.

There should be a safety trunk release located on the upper rear window deck platform- a black handpull . If it is still intact- it should pop the trunk lid.

Is the key that you have a genuine Toyota key? If so, is the key Black or Grey? If you have the grey key, you only have the "valet" key, and it will not do what you want. You need the Black key. Put the black key in the trunk and turn it 90 degrees & remove it. This controls the inside lever on/off for the trunk. The key hole will either be horizontal or verticle. One way lets the inside lever work, the other position stops it.

I have a corolla 2003 and I had the same problem. I turned the key to the left and the lock turned left, engaging the valet parking mechanism. I could not turn the key to the right and could not get access to the trunk because the lever next to the driver seat was disengaged.
The way I solved this problem is as follow:on the back driver seat I pulled the back seat forward to leave an opening and snick my arm in the trunck. Then I grabbed the cable used to latch the seat and I pulled forward, i.e. toward the front of the car. The cable is connectred to the trunck so that it can be disconnected easily if pulled towards the front. If you pull towards the back it will remain attached to the trunck. So grab the cable an pull towards the front, and it will release itself. Since the cable is flexible, you can pull it out of the trunk from the same the opening you put your arm, and then disenagage the driver back seat. Fold forward the back seat and get into the trunk and use the lever in the latch of the trunck to open it. The turnk will open.

If the lock does not turn, you need to disconnect the lock from the mechanism, so that the driver seat lever can start working again. To do this, and with the trunk open, remove the cover holded by nine plastic pins. Do not break the pins. After removing the cover, you will see the lock holded by two nuts. Remove the nuts with a rachet. The lock will be loose, and disconnect the lever that connects the lock to the latch. At this point the driver seat lever will start working again. Close the trunk and verify that the driver seat lever opens the trunk. Now you can open and close the trunk , and have time to call the dealer for a new lock.
Good luck.
