So there's four tumblers in here. I however feel dumb cause other than being an interesting zig zag keyway, I though it would be easy. Stuck a serrated tok wrench in there a short hook, then a gem, then reach, 2 rakes.... Long story short it ain't happening. Have set 1 pin, maybe. Any insight? It's cool cause the other lock at the top of this armored monster has a similar zig zag keyway but apparently uses alien technology, as it has no tumblers. Thanks in advance, I'm sure someone has come across these. P.s. I acquired this legally, and it's full of change. Would rather pick it (no destruction), so I can use it as a phone. But this f@#$%r refuses to yield.

pretty sure those are lever locks. much different to pick than pin tumbler.

Top is bottom tumbler

Keep in mind… Payphones are designed to STRONGLY resist vandalism. They are ( were ) often installed in remote unsecure locations…
My experience with payphones is the cashbox is far more secure than any “ Safe” sold at *mart.
My suggestion would be to buy a new cash box to fit that phone …. You are probably going to destroy the box to get it open, the replacement box will give you some idea on drill ,cut locations.

it's a Medeco payphone lock, if you are a beginner picker only luck will be on your side. Use an L rake or a half diamond, a hook pick wont open a Medeco unless you're very intimate with how a Medeco cam lock works. The pins don't just lift to the shear line, they also rotate -20, 0, or +20 degrees in order for a sidebar to fall into the holes milled into the sides of the pins. Even at 4 pins, they can be a real chore to pick.

Here's one on ebay, I think you'll find this is what you have.

At first I also thought you had a 29B Western Electric lever lock as others mentioned, just be happy you dont have Abloy locks on that thing..
Here's a Western Electric lever lock keyway: http://www.ebay.com/itm/200881006263

Edit: I just re-read your post, it would see you have Medeco bottom and Western Electric on top. I think you'll find the top door overlaps the bottom so you have to open the top first before you can remove the bottom. You wont be picking that Western Electric lock, I doubt any of us here could. Read this paper by Matt Blaze, it's very informational: http://www.crypto.com/photos/misc/wecolock/

hi can we see some photos of the actual keyways-locks ! on the phone

Yeah real sorry bout that. I figured payphones a payphone, but there's a couple different setups. Ilk be gone from work by 5, I'll snap n post immediately, sorry for the newb mistake. On a aside note, that's my, brand new, "Ken's"set, in the lower left corner of frame. (very proud of these) first new pics in almost 20 years!

NO worries ! id like to see the exact dimensions of the zig zag key way documented ?? if the stump can be viewed from a small hole a picking may be possible of this unpickable lever lock !

If this lever lock was picked in the passed it was done with a straight wire threw a pin point hole in casing that could easily be covered over and go un-noticed

and could be done in a few minutes with the right training

probably like this:

posted up in the secure area ! enjoy... ask one of the admin for access to this area as the possible opening method is part drilling it belongs in there

Here is 10ringo10's post: viewtopic.php?f=82&t=8554

If you can pick the cash box lock, you can get the change out without picking the top lock too, but to hook the phone up, you'd need to get to the electronics in the top part, and that means picking the top lock! I've never been able to pick a payphone lever lock, nor do I have picks for one. I did drill one out once, but that was no skill and all sweat and frustration.

Good luck!

Camera broken. But yes lever top, medeco bottom. Will drill out top, cause not interested in learning that type of lock. But working hard on that medeco.... Do you rotate to set side bar first, or set pins to shear first. Also having trouble rotating pins at all. Anyone know if the have the little groove GOIN up one side so you know which way to line them up? Or is this done just by feel?

Hardest four pin lock ever! It says I can't read Ringo post.... Im not special enough
