HAMILO Digital Door Lock, Keyless Lock, 4-7 Digit PIN, Compatible Door Thickness 30-60mm, Warehouse Anti-theft, Waterproof, Battery-free

This is a keyless digital door lock that allows you to set a custom 4- to 7-digit PIN. Although it's digital, it's an analog type that doesn't use any electronic components, so you don't have to worry about the lock failing due to a sudden battery failure.

If your door thickness is between 30mm and 60mm, it can be installed just like replacing a regular doorknob. Since there's no keyhole, there's no risk of picking. Made of a sturdy zinc alloy, it's difficult and time-consuming to break, and even a burglar will likely give up just by looking at it.

To set the password, press the C button on the door lock, then press one of the 4- to 7-digit buttons. To unlock, press the C button again and enter the set password. All buttons except the C button can be used as the password.

The buttons are large and long to prevent the user from misinterpreting the PIN. A switch is also installed on the inside knob to always release the lock. It's waterproof, so it can be installed in outdoor garages and warehouses, making it an ideal digital door lock for security.
