Access inside of mortise through cylinder keyway?

[cxseven]

This seems like an obvious idea so I bet someone has tried it before:

For some mortise pin tumbler locks which operate a cam, the keyway opens up at the back of the cylinder and would seem to allow threading a tool to the inside of the mortise and possibly pushing what the cam is meant to push. Couldn't this be used to manipulate a lever which would unlock the door?

I'm thinking some springy flat metal which would want to bend towards the lever might work.

Although this image is small, you can see what I'm talking about:

Here's another mortise with the cylinder removed:

What's the problem with this idea?

Here's a larger view of the first picture:

Peterson makes a tool specifically for this bypass. However, no further discussion will take place, because it is a bypass, which means it's advanced material.

We dont allow bypass discussion in public nor do we allow hot linked images,

Ive altered your images and locked the thread for the above reasons,


You are on to somthing though that a bit of research will tell you
