Anyone have any ideas to get into a locked, jammed trunk of a 2000 mercury marquis? They key, the remote, and the button on the door all do not work, although a clicking sound is produced. You can't access through back seat. I think its because some unnamed unsmart person jammed a ton of stuff in there (strollers, spare tire, tote box, chair) and its somehow interfering with the mechanism.
If the trunk was overfilled and had to be pushed closed, you might have success with pushing down on the trunk (with as much force as you safely can) while trying to operate the mechanism. If a force inside the trunk is pushing up, the mechanism could be in a bind. You pushing down will hopefully counteract that force enough to free up the lock.
Even if the seat does not fold down, you can unbolt it. Remove the bottom part first, then the back. This happened in my mother's Camry several times(bad latch mechanism) and I had to remove the seat each time.
Jam your hand up in there
Move crap around. push on it really hard, various things and keep hitting the remote while you do it. Eventually you will get into the trunk with brute force....but damage anything on you path.
You can reach in there and do it. My kid did it for a Malibu so you should be able to with the same.
I have one here, 2003, if you want me try anything.
