security lock

Hidden cabinet locks are screw-mounted inside furniture and connect to an external reader button by a cable; installation typically requires drilling pilot holes and basic hand tools. Smart deadbolt-style door locks are designed for DIY installation, fit standard deadbolt openings, and replace existing hardware using the supplied mounting screws and a screwdriver—often installable in minutes.

Sizes range from small concealed cabinet modules a few inches across to smart deadbolt units around 3.8 × 7.1 × 9.3 inches; cable and chain locks commonly list lengths near 6 feet. Weights vary from a few ounces for small padlocks to roughly 3+ pounds for heavier smart-lock assemblies or long chains.

Some listings provide explicit figures: a concealed cabinet lock may claim up to 50,000 cycles on four AAA batteries, while a smart door unit may reference a 10,000mAh rechargeable battery with an estimated ~180-day runtime.
