Instant Re-Keyable locks

[greyman]

I think there's two different types of lock being talked about on this thread. The first is a construction keyed lock, which is used by DOM, Kaba and others - these usually have a ball sandwiched in one or more of the pin stacks. You turn to a certain spot to make the ball disappear down a hole. which changes the pin stack and hence the key needed to operate the lock.

The other type is the clever type. I call these key-changeable locks. Rielda is one type but there are others. They generally have a system of racks that can be disengaged at a certain angle of rotation of the key.

The other type of key-changeable lock is a combo lock like Sargent & Greenleaf. DIfferent principle and can't be done using the operating key - a separate change key is required.

Sounds sexy, but do these use common inline pin-tumbler keyways we are used to cutting today? Or are we talking high security locks with interactive keys?

Yes, I believe Riedla keys can be cut on your everyday machine.

Nope - I was talking about rekeyable locks. Keys with mobile elements are a different story. Keys for Rielda/Lynx are restricted, so you'd firstly need to get the blanks.

U Change locks is one that comes to mind. I can't remember the manufacturer of the other I've seen in the past.

The U Change system have serrated tumblers that are held in position with side pins. There is a procedure, I can't remember specifically right now, but basically you turn the cylinder plug with the existing key to a certain position, insert a changing tool to separate the serrated pins, put in the new key, remove the tool and it's set to the new key. Or something like that.
It's available through an American company.
I'll try to find some more info on it as well as the other brand.
