LockeyUSA Deadbolt Locks have a range of different finishes and options for locking doors. Most of these product options feature a digital keypad, which offers keyless entry and convenience. Some models offer a completely hands-free experience by coming with a remote to control them. The difference between a deadbolt and a spring bolt lock is a deadbolt can not be opened without a key, whereas a spring bolt opens when force is applied to the bolt itself. Also, a spring bolt lock is held in place with a spring, and a deadbolt lock can make entry tough without the correct key.
