GJ Locks Brattonsound sentinel make-up Key

A new revised version of the Brattonsound sentinel make up key complete with pins stored in the handle.

There are only 3 heights used in this lock. The empty key is one height then you have short and long pins.

You can use a scope to visually decode the first throw.

Also handy to rekey the lock on site if you don’t have a new lock at the time.
