If you go away for a few weeks and need to give your key to a housekeeper, babysitter, or dog watcher while your away, who knows whether that person is going out and making a copy of the key, with some sort of diabolical plot for thievery planned on your return. The ViprLock ensures that something like that could never happen, with its easy key lock changing.
The standard ViprLock comes with an A & B key lock, but add-ons are available for up to six different key options. Switching the key setting is as easy as depressing a special button while using key A, and then using key B to unlock the door. The two-key unit is available for $60, with extra key settings for $3 each.
