Folks,

I have a number of MCA RS/6k machines that are lacking their keys. Has anyone attempted to get the pinout for the 3-pin connector wired to the keylock?

The keylock is the one pictured here:

The lock itself is here:

The connector is pictured here:

I don't have a key to turn the lock to determine what pins are high and low for service, run and lock modes.

Thanks!
- Alex

So, would it have killed you to identify the system it's for?

Look at the top illustration, note the three key positions.

Possumbly like this, I no longer have any 7006 systems...

If you look at the assembly, note the blue cylinder below the silver
lock cylinder. Further, notice how the white ABS plastic frame holds the
blue cylinder on the end of the lock cylinder.

That blue cylinder is the crux of the matter. My SWAG is there are no
electrical connections inside the silver lock cylinder.

Pull the blue cylinder out, I <ASS U ME< that it is not riveted to the
silver lock cylinder.

Are there any markings on the blue cylinder? Again, I <ASS U ME> that it
is an optional part to a keyswitch...

If you can remove the blue cylinder from the silver lock cylinder, it
<should> be possumble to set it to each of the matching key cylinder
positions and sweep the pins.

CPT Obvious, out...

Thanks so much, Louis.

Indeed, as you surmised, this is a 7011-250, but I had discovered that multiple of the MCA RS6k systems had the 3-pin keylock connector. I didn’t find that link to the pin out, so I really appreciate you pointing it out.

It’s really too bad that the cylinder is a Medeco, as otherwise I could probably get a locksmith to make me a key for the cylinder. I’ll probably replace the lock cylinder with something generic, if I can actually get it apart without breaking it.

We need feelthy-feely pictures. It would be nice if there were OEM model
#s on the lock cylinder. BUT... it could end up with getting the
dimensions of the lock cylinder AND that of the blue keyswitch.

By the way, back in the day it was possible to get a version of the keylock assembly that did not need a key... most of the 7009s (models C10 and C20) came with "no key needed" keylock assembly.

65G8290 Operator Panel Assembly with Keyless Lock

nothing on the lock itself. Just a three position knob?

The pictures in the manual are a bit deceiving... look at pages 3-2 (45) and 3-7 (49), and you would think, "Oh, it's just got the keyway, you'll need to use a small screwdriver to move it". What the pictures don't show is the large curved notch going across the lock core that readily accepts the coin of your choice (a quarter works really well). There was also a plastic knob that fit in the keyway to make the job even easier, but that piece was regularly broken or lost.

If someone was wondering, "how hard would it be to single-pin pick a Medeco lock like the one used in the RS/6000 keylocks", the answer is: harder than a Masterlock #3, but not difficult. The LockPickingLawyer would knock it out in seconds, a mere mortal like you or me would need a few minutes with a short hook and turning tool. Once picked, turn the core just enough to keep all of the pins aligned on the shear line, remove the clip, push the core out, remove all of the key pins, driver pins and springs, put the now-empty core back in place, and now you have a "keyless" lockset that you can move with any key or small screwdriver or plastic knob that you create on your 3D printer.

Still alive?
