My trunk won't open

Something broke on the lock mechanism. In order to open the trunk, you will have to remove the rear seats and try to access the trunk area. Once you are in the trunk, you should be able to manually open the lock and investigate what broke.

A Saturn Sky is a 2 seater and has no rear fold down seats and no key to open the trunk lid.

When you pull the trunk handle back towards yourself to open the trunk, it may be sticking in that position, so give the handle a tap to pop it back into its original position. Then shut the trunk and see if it has latched.

When you press the trunk open button, do you hear any "release" noise come from the trunk area? The issue may be a bad battery in the key fob OR there could be an issue with the transmitter located inside the vehicle. Do the doors lock and unlock properly? is the vehicle equipped with security or immobilizer? please advise

Lower the back seat and crawl into the trunk and see what the latch is doing when you activate the key fob. the trunk lid will have to be open to enable any repairs. Also an emergency release cable is probably visible (yellow handle) inside the trunk and will Open the trunk lid.

Fixed. In the glove box there is a vallet button. I pushed it and now my trunk and fuel door work. and what this has to do with my trunk and fuel door not functioning , I have no idea. Hope this helps someone else.

check trunk fuse

1. Open trunk
2. Place latch in lock position
3. Pull inside trunk release to see what isn't moving
4. If trunk key won't turn, the key may be worn out and need to be replaced

The trunk latch is operated by a solenoid which it requires power to operate. since the batery is flat then it won't work. I'm not sure where the positive terminal is under the hood but you can connect the positive lead to the alternator wire terminal, and the negative lead can be connected any where on the engine.
Good luck......
