The Speed Release Gun Lock features an electronic trigger locking system encased in a high-impact, tamper resistant polymer that covers the trigger and trigger guard of most handguns, shotguns, and rifles. With a new 9 volt alkaline battery installed, the lock will operate up to twelve months or approximately 800 cycles. The lock has a lighted touch pad for night use and a fully programmable security code that offers up to 38,000 possible combinations. You can push one button at a time or two buttons simultaneously which counts as one button stroke. When the correct code is entered it allows instant access to the firearm. 

The lock is equipped with a memory chip, it will not lose your personal code in the event that you allow long periods of time to pass without changing the battery or if the battery is disconnected. The lock stays engaged if the battery is depleted. Just simply place a new 9 volt alkaline battery in the lock while it is placed on the firearm. Enter the four digit code and you have access.
