If you expect a deadbolt on your exterior doors, you probably want one on your handgun safe, too. Most homeowners demand deadbolt exterior locks in addition to traditional latching door handles. You can see this in the videos above and below, and many others on the internet. UL 768 rated electronic locks generally use a motor with a reduction gearbox to actuate a deadbolt, making them more expensive than small-gun-safe latch-“locks”.Īnother issue with spring latches is that they can be unlatched by poking various areas of the mechanism. UL safe experts test for this type of obvious design flaw before approving them. UL rated safe locks cannot be bumped in this way. For example, Harbor Freight handgun safes were recalled in 2018 because they will “ can open without the use of a key or combination upon impact“. Simply bumping the worst of handgun safes can overcome the spring holding the plunger, opening the door.
There is a direct trade-off between the strength of the spring and battery life of the “lock”. On solenoid latches especially, this spring must be weak to allow the battery-powered magnet to overpower the spring without draining the battery too quickly. When no electricity is applied, the only thing holding the latch plunger locked, and the safe locked, is a small spring. The mechanisms vary, but these models have one thing in common. This can be directly as shown in the illustration, or through a mechanism.Įntering the combination on the keypad energizes a solenoid coil or motor to retract the latch plunger. Like a screen door, a spring loaded plunger protrudes to the door latch. The “lock” on most cheap electronic handgun safes is a battery-powered latch, similar to the latch on a screen door.
