those keyed Master combination locks

It depends on the keyway...

Many of them are M3 (ilco 1092VR) but some are a 4 pin varation of: M17 (ilco 1092C) which can be cut down and used...

Master has the blanks and controls them pretty close..and wont sell UNLESS you are the 'owner of record' --Shiva--

that's what i figured

..and wont

and even then they are probably precut right?

There are several keyways I've seen. Check with your locksmith wholesale house.

where can they be bought?

That is NOT true...

OEM blanks maybe, but ilco makes blanks that work perfectly...

Those little override keys were one of the most popular things that every administrator at the school I used to work for would want... Or a new coach for the atheletic padlocks... Most of the ones I saw (V36, V56, V63, V68) were M3 blanks...

yes, they get shipped to the original owner --Shiva--

but if the blank is off patent, then anybody can make and sell it i suppose.

Hi Bill:

Rather than going to the trouble of impressioning a control key for your Master Combination Lock, which will let you change the combination from the several that are built into it, and get the lock openly without the combination, just phone up Master Lock in Milwaukee, WI and ask them to sell you a control key, or visit your local Master Lock distributor and buy a control key off of them.

You will probably need your lock's serial number, stamped on its body, when dealing with Master Lock, as while one control key usually fits several hundred locks, it may or may not work every Master Lock combination lock with key override ever built.

Please let us know your success in obtaining a ready-made control key for your lock.

The padlocks with the keyed override do not have the capacity to change combinations... I think you have confused the key bypass that padlocks have with the control function that the built-in locks have...

Second -- I haven't run into combo locks with the same override key number in my area -- I think that the factory works hard not to flood the market in any given area with too many repeats of the same key code for these kinds of products...

Having had the experience of ordering a key for built-in lockers once (the only one was lost) the school had to provide information supplied on the original sales invoice in order to obtain a replacement key...

There are no code series for those kinds of keys available as far as I have been told -- the only way to obtain replacement keys is via the factory... I have been told that without the particular information Master Lock requires it is easier to order more locks with that code number and request additional keys at that time...

Only bypass I have is M17-1092C, And I'm thinking that is for built-ins. Not sure 100% though.

Hi Evan:

Yes I was confusing the key override function of Master padlocks as used say in rec centers and such, with the key override and combination changing functions of the Master built-in locks, commonly used on book cabinets and small lockers in universities and colleges.

What I have seen of the built-in locks is they are usuallty stronger than the sheet steel locker door they are attached to.

Have seen a number of book cabinet doors belt at a 45 degree angle by someone that wanted in real quick, probably in the dead of night.

Back in my university days, some of us students found people commonly put their combination on the back of the card with their name on it on the door of the locker!

We also found several lockers with locks so worn even my grandmother could have manipulated it open without the combination.
