Problem: Key locked in trunk of 2002 Ford Focus. Trunk button won’t work. How can I get into the trunk?

Do your seats come forward in the backseat? If they do check every ford I rented lately had them
If not you may need to just pop the lock out

Several answers. You can go to your dealer, and he can either cut a key, or sometimes a mechanic can pick the lock. You can try removing the back seat, and maybe able to crawl into the trunck that way. If you have a spare key, that might work.

Try removing back seat, if truck buttton doesn’t work, the fuse is burnt and the fuse is in BACK CENTER of the fuse box. Need a mirrrow to replace fuse
You can always remove trunk buttton switch and hook direct battery current to the trunk latch wire

Go to Ford dealer with proof of ownership monday and have them cut a spare key to the car… They can cut a key to the car that can open the doors for you but won’t start the iginition.

Either that or you will have to take coat hanger and bend the seat up to get at the keys as the lock for the backseat (and access to the bolts) requires getting at the latch (in the trunk)

Replace the fuse for automatic trunk release button located most generally under the drivers side dash panel.See owners manual for exact location

That was silly, take your car to your local garage, they should have your key number on record to cut you a new one, before that try bringing your backseats forward you shud be able to pull them down to acces boot, if both them dont work i think a new rear window would be cheaper then replacing the whole lock cause you might have to end up doing all doors.xx

no money! tear out the back seat any way you can and get a small person to retrieve the key.
