The functionality of a smart lock depends not only on the quality of the product itself but also on the precision of its installation. Any deviation in either of these aspects can lead to suboptimal performance and may even result in consumer complaints. This article aims to provide installation professionals, especially those with limited experience, with a thorough understanding of common smart lock failures and their general solutions. The focus is on issues encountered during the installation process and post-installation troubleshooting.

Common Issues During Smart Lock Installation:

• Handle Fails to Return:

During the installation of locks, especially those with U-shaped handles on both sides, there might be instances where the handle does not return after being pressed down.

This issue can be attributed to two main causes:  Misalignment or insufficient size of the square hole, causing friction. If this occurs due to misalignment or a  small hole, it is essential to review the blueprint, realign the holes, and, if necessary, enlarge the hole area.

Tools needed: Milling cutter, tower drill, hole opener (use a milling cutter for smaller adjustments), electric drill.

• Deadbolt Doesn’t Extend, Making it Difficult to Close the Door:

If the deadbolt fails to extend, and after ruling out lock body malfunctions, consider whether the holes in the door frame are incorrectly sized. In such cases, use an angle grinder to re-drill the holes based on the comparison with the blueprint. Alternatively, install a guide plate if the door gap allows.

Tools needed: Angle grinder, blueprint (experience can be relied upon for precise adjustments).

• Difficulty in Deadbolt Extension, Causing Door Closure Issues:

This problem is related to the guide plate. Use a milling cutter to enlarge the hole in the guide plate. It is advisable for novices to compare with the blueprint to avoid over-enlarging, which could result in door instability.

Tools needed: Milling cutter, angle grinder (use if milling cutter is unavailable).

• Front-to-Back Movement of Door After Installation:

If the door exhibits front-to-back movement after installation, there are two possibilities: either the door gap is large, or the position of the door frame hole is excessively wide, causing the deadbolt to wobble. To address this, manipulate the two guide boards on the deadbolt hole in the door frame inward or apply weather stripping on the door to stabilize the deadbolt’s entry into the guide plate.

Tools needed: Hammer, wrench, pliers, angle grinder.

• Excessive Force Required to Close the Door After Installation: 

When considerable force is needed to close the door, it is likely due to the lock point being too far forward. In such cases, use an angle grinder or milling cutter to expand the door frame hole forward. If there are guide plates, consider moving them forward.

Tools needed: Milling cutter, drill bit, electric drill, hammer, flathead screwdriver, cross screwdriver.

• Recognition but Failure to Open:

During installation, if the lock can be recognized but the motor fails to open the door, check if the square steel bar is too short. This is especially pertinent when installing mechanical lock bodies or double-quick double-activity lock bodies, where the square steel bar may not enter the handle hole.

These comprehensive troubleshooting methods for common smart lock failures during installation aim to empower installation professionals with the necessary skills and knowledge to ensure optimal performance and customer satisfaction.
