I would say that if you are having this problem most likely the latch has been slightly bent in or out, or the vehicle has been wrecked in the past. Also, the alignment of the trunk could be off. (wrecked) But a trunk latch can get damaged from slamming it over and over. Also, if it is a used car, you never know what has been done to the vehicle. Maybe someone locked their keys in the trunk and broke the latch in the past. Or, maybe someone broke into the car when it was previously owned and the latch has been replaced. You never know. People do strange things.
Answerit could be the solenoid going bad or i would try lubing the latch system first,maybe its sticking.The latch may need adjusting or the door got twisted.
Check that the latch is working. With the door open, Push the latch back with a screwdriver, & make sure it is holding in the closed position. If it does not hold closed the lock or inner door actuating mechanism may be faulty & would possibly need to be replaced. If it does hold closed, it should be just a matter of adjusting the striker plate.
To fix a trunk latch that is stuck open, the teeth on the lock may have to be adjusted so the trunk will close. It is also possible that the cable for the trunk latch is broken. To fix the gas cap door latch may require a little bending and adjusting with a pair of pliers.
Should be on a sticker in driver door frame, and sometimes a metal plate near hood latch.

Most hood releases consist of a latch tucked under the hood, but above the grill. If you place your fingers under the hood, usually to the right of center, you will feel the latch. You will lift the latch, and the hood should pop open enough to get your fingers under it. Then, it releases fully as you lift the lid. Two problems can occur on hood releases. One, sometimes the piece of the lever that you should lift up on has broken off. Second, sometimes the piece is there but it wont pop the hood. You could try to release using the safety latch. Or, you could try to pop the hood by placing your hands on the hood, one on each side off center. "bounce" your hands forcefully in a down-up motion and you should hear the hood latch "pop". Use your fingers to try to lift the hood. Sometimes you have to repeat the bouncing motion several times before the hood releases.
put a screwdriver in the latch pull the handle and apply pressure to the screw driver should pop the latch open
Adjusting the steering wheel on a 1998 Toyota Corolla is easy. All you have to is find the latch at the bottom and push in to adjust the wheel.

Sometimes trunks on cars pop up when the latch is broken. There may also be something stuck in the latch preventing it from catching the other end.
On the 2004 model (as well as some others) there will be two screws on either side of the latch as you look at it with the gloe box door open. Simply remove those two screws and press on the latch and it will come out. If your latch broke as mine did you may have to use a little bit of pressure. Once you have the old latch out place the new latch in the slt and replace the screws.
