It features chrome-plated solid steel locking bolts, a vertical locking bar, a glass re-locker, pre-drilled mounting holes, and an electronic keypad lock for extra layers of security. In addition, two (2) adjustable/removable shelves come with the product for convenient storage. Four (4) “AA” batteries are needed to operate the electronic lock (not included).
