Unlocking the Secret of the Trunk Lock

I finally got to putting in a new trunk lock today.  Two different people had told me the job would require a special tool, because the circular ring-nut that holds the cylinder in place had rusted and glued itself firmly to the barrel.

1) The old lock with its devilish ring
The trunk lid itself, where the locking mechanism is located, is awkward.  After I removed 4 bolts and the mechanism, access became easier.

2) Recessed into the sheet metal and barely visible in dim light, the trunk lock is difficult to get at

A trusty pair of needle-nose vice grips proved up to the task of removing the nut. Thanks one more time to the folks on bmw2002faq.com for the hint.

After that, it was a simple matter to line up the notches in the trunk lid with the new cylinder and put in the new lock. Now I can safely store all the groceries that I usually carry on the back seat.

3) Locked

4) Unlocked
