How (NOT) to gut a medeco switch lock [FULL POST]

So, I have a few of these, and I wanted to take one apart and have a look around. I made a mistake in judgment as to how it was assembled so I would up destructively disassembling it by filing a ring around it. Now that said, it did prior to filing have very handy guide marks in the exact place to file... heh, the dirty bastards. The cutting, as it turn out is unnecessary, and one can actually remove the "half moon" retaining clips without such drastic measures by banging the shit out of one side of each clip until the other corner of the same clip raises enough to pry it out (Thanks FarmerFreak for that tip.)


These as other medeco cam locks are driverless, only keypins and a sidebar. So, basically you still have to rotate and raise the pins; however, instead of lifting the keypins to a shear between themselves and the drivers, you are looking to get the height and rotation right simultaneously so that the finger-pin from the sidebar will engage into a hole in the side of the keypin. to make things more interesting, they do include "false holes" that are too shallow to fully engage the sidebar pin. These false holes are deep enough however, to be able to capture the finger-pin from the sidebar. The keypins are also spooled at different heights (depending on the pin it may be either above or below the hole as well) just to make things more interesting. Some keypins may not have the spooling.

The pics can be clicked on to get a bigger and clearer view of any of the items too! Also, once you get the larger view you can click once more to zoom in further.

Pins - Notice the holes and spooling mentioned earlier... also the only pin in this set with false holes is the unspooled one.

This spring pushes outward on the plastic cam that actuates the SPDT micro switch:

This is one of the "half moon" retaining clips... it is pretty badly mangled. I'd have gotten a pic of an undamaged one, but I dropped it and the garage floor ate it:

This is the outward facing side of the microswitch with the poles for connecting leads. The center pole is common:

Bezza, see the red bold text in my first paragraph... you can do it non-destructively. FarmerFreak gave me a tip on that last night.

Well, yeah, so I found out last night, but it was too late by then LOL! The clips were in way too tight to get anything under to pry, I am going to try out FF's suggestion on another one as I still have a few more.

Awesome write up, I also have one of these that I picked up for something in the region of $5 from eBay. Didn't have a clue on how to take it apart. Thanks a lot.

I have one or two of these, only they are vending machine locks I believe. Those springs are the biggest craziest things around!
