Master Lock 175 178 Combination Reset Key
Description
Needed to reset the combination on a master 178 after decoding it and I didn't have the tool. I took measurements of the keyhole and did some guessing based on photos I found online and made this small key that works just like the original. I included one with a 4mm hole if you want to put it on a keychain, though I have not printed this version. To use: <ol> <li>Unlock or decode the lock</li> <li>Slide in the tool and press it into the back of the hole on the bottom side of the lock, you will feel spring pressure pushing back.</li> <li>Rotate the tool 90 degrees either left or right to lock it in place while pressing the tool inward.</li> <li>Dial in the desired combination. (If the tool is inserted and seated correctly, the wheels should spin freely with no detents, or at least a lot more freely than normally dialing the combination)</li> <li>Remove the tool by rotating 90 degrees in the opposite direction and sliding it out. <li>Combination should be set now, remember that the lock will not lock itself while the combination is dialed in.</li> </ol>
