2005 ford focus need to fold back seats down.

Remove back seat ,bottom first push seat in the middle with both hands ,lift after you have pushed on seat this releases the catch.remove the top part of the seat you will need to remove 2 screws lift srtaight up the seat will come out ,now you will see sound deadning material ,remove ,carefull not to tear,with flash lite look at inside of trunk lock area ,you will see a slot on the latch ,use regular flat screw driver to insert into slot just turn right ,left the trunk will open .you can take out trunk lock cylender out and any lock repair shop can re key the lock by looking at the tumblers inside the cylender.Good luck I know this will work ,sounds like a lot of work but not realy.
