This morning I punched in the combination to my Gun Vault GV-2000D. There was
a whirring noise, but that's it - the door didn't open. I tried it several more times, then
resorted to using the mechanical key.
Later I called Gun Vault and was told that it's most likely a broken cable that
a motor tugs on to unlock the mechanism. My unit was made in 2005, and was no
longer under warranty. The guy told me new units have been redesigned in this
regard. So I had two choices - buy a new one or try to fix mine.
Since I had nothing to lose I opened it up. It's actually very nicely made and
easy to service. The entire guts is contained in a small metal box that's held
by three screws. Inside that box is a PC board, the motor, and the locking
mechanism. I saw right away that the cable was indeed broken. They used
braided steel wire, like the kind used to hang pictures on a wall. Every time
the motor turns on, it wraps the wire around its shaft, which tugs on a lever
that unlocks the box.
Why they chose steel wire of this kind is beyond me. That stuff is not
intended to be bent back and forth many times. And it's way too heavy for this
application. It's surprising since they did such a nice job on the rest of
the box.
Anyway, in my case there was a stub of that wire still attached to the motor
shaft (crimped on). I took some 30 pound nylon fishing line, tied it to the
stub, and wrapped a few turns around the shaft. Tied the other end to the
unlocking lever, and I was done. It works flawlessly. I think nylon will last
a long time in this application. There's very little force involved. Mostly
it's just the line wrapping around the shaft a couple of turns each time. The
wire couldn't take that. I'm surprised the wire lasted as long as it did. I
access the box at least 10-15 times a week and it lasted about 2 years.
So now you know what to do when your Gun Vault goes "whirrrrrr".
