Review on 🔒 Colosus NDL319: Keyless Electronic Door Lock with Smartcode Security and Keypad – Grant, Control Access for Home, Office, Rental Property, Gym (Silver - 4 Key Fobs) by Javarie Brumfield

I installed this lock on July 18, 2019. This lock was very easy to install and matched my previous door knob. I just had to drill a new hole for the smart door lock as this lock uses 3 screws to hold it together. I only have one complaint: this smart door lock only stays open for a few seconds. It would be great if when you press the unlock button on the remote, it stays unlocked until you press the lock button, like you do when you open and lock a car door.
