DIY Remote-Controlled Lock Upgrade

If your home features a lock similar to the one described in the article, you may want to consider a DIY project to create a remote-controlled motor lock.

The setup includes a plastic case and a HONGTAI motor lock. Each of the two motors comes with its own separate remote control for convenient operation.

The system includes two sets of remotes, two sets of batteries, and two motors, each tailored for optimal functionality.

Inside the plastic case, you'll find a combination of two motor drives, a wireless module, and an HT7333 voltage regulator. These components are securely held together with 3M double-sided tape. For additional safety, you can install an undervoltage alarm circuit later on. When the lock begins to struggle, it's an indication to change the batteries. Currently, the four Double Deer batteries provide a voltage of 4.4V, sufficient for smooth locking and unlocking.

The latch mechanism has been modified from the original square tongue to a 12 mm stainless steel round rod, making it easier to drill holes in the door frame. The internal lock rod is longer than the external portion, ensuring durability and resistance against potential break-ins, regardless of whether the door opens inwards or outwards. Many locks, including safes, would benefit from a similar design, though it might require more internal space.

This DIY project is a practical and secure way to enhance your home security while offering the convenience of remote control access.
