So I tapped the hole, then installed the lock. Cannon only taps the holes that they need, so the threads had not yet been cut in the top right hole.
To mount the new S&G lock, I needed the bottom two and the top right. There were four mounting holes in the safe for mounting the lock, but only three were used for the original Kaba lock –the bottom two and the top left. This would not have been on a problem on the previous safe, which had a lot of empty space behind the door's outer layer. The hardplate was right up against the safe door's outer layer, so the mounting screws had to be shortened. The safe was open and its owner had a new S&G Z02 lock and keypad for me to install, which he had received from Cannon Safe. My job on this one was to replace a malfunctioning Kaba Mas LC lock and MX keypad. This hole in the panel is filled with a plastic plug that was somewhat difficult to remove.Ībout three hours later, I arrived at a second Executive Vault. It's not applicable to this lock, but it could potentially be used for scoping the change-key hole of a mechanical combination lock. Note that the panel of sheetrock on the back of the door has a hole for a change key. As seen on the label at the edge of the door (Figure 6), this safe was made in the 4 th quarter of 2007. The safe now works beautifully, but I'd like to know more about the cause of the lock failure. I repaired the hole I had drilled in the door of the safe, installed a new lock and keypad, and moved the door seal strip to where it belongs, as in Figure 5. At the bottom of the door, the left half of a door seal strip was out of place, as seen in Figure 4. I initially thought that the door needed some kind of adjustment, but I soon found the culprit. As it turns out, it had been this way ever since the owner acquired the safe. I rotated the three-spoke handle counter-clockwise to retract the boltwork. (The mild steel, hardplate, and zamac were all penetrated with a single 5/16” StrongArm bit.) With a small flat-head screwdriver, I easily slid the solenoid plunger to the right, unblocking the lockbolt. (It had to be done this way in order to prevent drilling a hole through the template's base plate.) Then I mounted my Magnum Bullet II drill rig, as shown in Figure 1, and drilled the hole seen in Figures 2 and 3.
Since my chosen drill point was very close to the bottom hole, I tapped the left and right screw holes and fastened my Helix drill template using those holes instead. Note that the safe had four screw holes for keypad mounting but that only the top and bottom ones were tapped. This means the solenoid is horizontally oriented, with its centerline about 11/16” below the center of the cable hole. Based on this, I knew that the lock was mounted in the standard position with the lockbolt pointing downward. I could also see that the cable inside the safe was routed leftward from the cable hole. Within the lock, this little hole is located where a typical mechanical safe lock would have its dial spindle. Looking through the safe's cable hole, I could see a 1/8” hole in the lock case. To determine the location of the solenoid, it was necessary to ascertain the orientation of the lock itself. I decided to drill for the lock's solenoid.
Some people are better at electronic diagnostics than I am.) (I'm not entirely satisfied that there was no way to make this lock work. I concluded that the logic in the lock's electronics was, for some reason, not functioning properly.Ĭonsidering this problem to be beyond my ability to correct while the safe is locked, I moved on to opening the safe through frontal penetration. I used the code, but the lock did not give the confirmation beeps that I expected to hear afterward.

I connected a new keypad with a new Duracell alkaline battery and tried again, but the outcome was no different.Ĭannon had given me the management reset code that should reset the lock's combination to 123456#. I rotated the three-spoke handle in the closing direction (clockwise) to ensure that the bolt carriage was not in contact with the lockbolt, then tried the combination again. This is known to happen when the boltwork is resting against the lockbolt. The keypad responded to each button press by beeping as usual, but when the proper combination was entered, the solenoid did not click. My job on the first of these Executive Vaults was to open it and replace the malfunctioning Sargent & Greenleaf Z02 RotaryBolt lock. These “vaults” are gun safes by Cannon Safe, Inc. One day I had the privilege of working on two safes by the same name– Executive Vault. I've done a lot of work on gun safes lately.
