When trunks get older, sometimes the latches get stuck. To fix them a person needs to add oil to the latch to loosen up the parts of the lock and turn the key hard.
your trunk latch may be stuck in the open position. The latch pushes to the left to open, try pushing it to the right and see if it pops into place.
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.
It sounds like a problem with the remote, if you have one, stuck in the "open" position. Otherwise use an oil penetrant and work the latch manually until it returns to its normal position. Note: it could be stuck in the closed or shut position too, but less likely. Then you would need to try and get the latch itself open, even though the trunk lid is already open.
Remove the power trunk release, it may be stuck and holding the latch to the open position. I had same problem and found that if I use the key to unlock power lock then closed trunk - it worked.
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.
go through the back seat, open the trunk cover, a few screws and than pull the latch to the lock and walla you have it opened manually
you get something very stiff and keep trying to lever it open, if this doesnt work smash the uncscrew the screws and crawl in, if this doesnt work then just brake your trunk
Try lubricating the latch with WD-40, and then working the mechanisim back and forth for a bit. Make sure that the latch is moving all the way to the 'open' position, as failure to open properly can cause the latch not to engage.
I think you need to take out the back seat and go thru the trunk and turn the latch manully, then check your lock cyc. connection to the latch assembly.
hmmmm....can you open it from inside? My rear door latch gets stuck in the open position at least once a month on my '01 CRV. I've found that the hinge and spring get rusted up on the latch. I spray a rust inhibiter/lubricant (PB Blaster) on either side of the latch and then work it until it moves freely. This is a poor design for something that is exposed to the weather.
This happened to me . The net in the trunk was caught in the latch. I pried the boot gently with a large screwdriver while pulling the handle to open it after pressing the inside release. Then we took out the so it won't happen again. You can't take down the rear seat back because the release is in the trunk.
I beleve it is the Johnson rod. Sometimes they get stuck upon fermentation and stick the circuit open causing the battery to discharge.
