78’ Snap-On Toolbox Lock Cylinder Replacement KR555

[Catcher1984]

Hi I recently got a KR555 and it has the original lock without the key. I know I can buy the key off eBay for about $15 but I have some spare locks/lock cylinders/keys

How do I go about swapping them out? I’m pretty sure I just need an adapter but don’t know the correct term for it. It’s a square piece that sticks out the back and the rod things centers on it then gets screwed in place.

Before you get too far make sure your new lock is a quarter turn lock, as your original should be.

what you need is a cam lock adapter. https://mrlock.com/part-cam-adapter...MIgvaYxfSZgAMVXRWtBh3AVw-XEAQYByABEgLx_vD_BwE

that square pc that sticks out the back of the lock accepts the cam ( the latch with the square hole in it) and is part of the lock plug ( the part that the key fits in to )
you could probably strip a cylinder down and use the wafers & keys in the original lock. it will take some patience and careful not to loose springs & wafers

Thank you I was having trouble figuring out what all the pieces were called. I actually ran into another problem with the lock bars. The one on the right is really rough I had to use a piece of wood and hammer it up/down to loosen it a bit. It doesn’t look like I can remove it what are my best options should I use degreaser then oil to free it up?
