Do You Need to Replace Your Door to Install a Fingerprint Lock?
Fingerprint locks are designed to accommodate most standard lock body specifications on the market, such as cylindrical locks, square locks, Xiaoshuai locks, Ba Wang locks, Wang Li self-retracting locks, and others. Generally, most doors can be fitted with a fingerprint lock without replacing the door. Exceptions include rare or foreign lock bodies, which may require drilling additional holes in the door. If you want to install a fingerprint lock, manufacturers and skilled installers can usually find a solution.
Confirm Door Swing Direction, Lock Body Size, and Presence of Multi-Point Locks (Top/Bottom Hooks).
Are There Material Requirements for the Door?
Modern doors come in various materials, including outdoor metal doors and commonly used indoor wooden doors. Some may worry that wooden doors can’t support fingerprint locks, but this concern is unnecessary. While thieves are known to pick locks, they rarely break down doors. Fingerprint locks can be installed on wooden, iron, copper, composite, and security doors. Even glass doors in offices can use specialized glass door fingerprint locks.
How Thick Does the Door Need to Be to Install a Smart Fingerprint Lock?
Door thickness is a critical factor when installing a fingerprint lock, as it determines the lock's fittings. Smart fingerprint locks typically fit doors with thicknesses between 40mm and 90mm. For thicker doors, special notes should be made when purchasing. Doors outside this range cannot accommodate such locks, so measure the door thickness carefully to ensure the customer service team can recommend a suitable lock.
What If You Have Double Doors—Do You Need Two Locks?
Technically, double doors require two locks: a functional lock and a dummy lock. This setup is for convenience, visual symmetry, and aesthetics. A dummy lock (same brand and model) is installed on the second door, with the lock core and latch removed, leaving just the external shell. This configuration is common for villas, where double doors are often made of heavier metal. To make opening such doors easier, consider fingerprint locks with large handles before purchasing.
Can You Install a Fingerprint Lock Yourself?
DIY enthusiasts might find installing a fingerprint lock straightforward by following the instructions. However, improper installation can lead to issues or even damage the lock. Damage caused by self-installation typically voids return or warranty services. For safety and convenience, it’s best to leave this challenging task to professional installers.
