Sargent & Greenleaf U12 – Frequently Asked Questions
1) What is a Sargent & Greenleaf U12 change key used for on a safe lock?
The U12 is a change key, the tool used to set a new combination on a mechanical safe lock rather than to open it. It fits standard size Sargent and Greenleaf locks built with four wheels, which is the wheel count that governs how many numbers the combination carries. It is not an operating key and it does not replace the dial.
2) Will the S&G U12 change key work on a three wheel safe lock?
No. The U12 is cut for standard size locks with four wheels only. A three wheel lock takes a different change key, so count the wheels on your lock body (or check the combination length) before ordering this one.
3) I manage a building with several S&G safes. Is one U12 change key enough to recombinate all of them?
One U12 covers every standard size Sargent and Greenleaf lock in the fleet that has four wheels, so a single key handles the whole group if they are all that configuration. Mixed fleets are the catch: any lock that is not a standard size four wheel unit needs its own change key. Sort the safes by lock size and wheel count first, then buy per group.
4) Does the Sargent & Greenleaf U12 open the safe if I have lost the combination?
It does not. A change key only lets you write a new combination into a lock you have already opened on the existing combination. If the combination is lost, the U12 gets you nowhere and the job is a drilling or manipulation call for a safe technician.
5) How many order options does the S&G U12 change key come in?
There is one configuration, the standard four wheel change key. No handing, finish, or length choice to make, so the only thing to confirm is that your lock is a standard size unit with four wheels.
