Removing a Trunk Lock Cylinder with no Key
Removing a trunk lock cylinder with no key. January 2016
I gradually increased the size of the hole using larger bits until it was large enough to insert a carbide rasp which was about 1/4" in diameter. The rasp has a flat end so it would not grind deeper into the cylinder. I then used the rasp in my drill and proceeded to carefully grind up and down until there was only a tiny amount of the original cylinder wall left on the top and bottom. That also destroyed the pins in the cylinder and the pieces could be pulled out with a hooked pick. I used a narrowed hack saw blade to cut the remainder of the cylinder walls. That may not be necessary if the cylinder will now turn.
I then turned the cylinder a bit and inserted a small allen wrench into the hole on the bottom side of the housing, which is accessible without disassembling anything, and pushed the spring loaded retainer which released the cylinder. It is easy to feel the spring loaded retainer when you have it lined up. Steve Brown |
