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 Jason Dahlkemper

I just installed this lock; it took about 1.5 minutes (watched installation video, read instructions, drilled hole, assembled lock); This works fine; the instructions for saving the code are simple; The only thing that took a little longer is that you have to reprogram the code from 6 digits to a 4 digit code. Most digital door locks allow up to 8 digits to be entered. No need to reprogram (this lock comes factory installed 6 digits). RFID tag and remote control work well; With the remote control, you have to wait a few seconds for the lock to pick up and process the signal. I am happy with the lock so far, since my first day on this lock, no adverse events; Let's see how reliable it is in the long run? I will let you know in two months. If you have a door with two locks; (top and bottom) you need to install this digital lock top hole and bolt lock bottom hole; Otherwise you won't have enough vertical clearance to fit in the bottom hole. The lock is made of durable material. The number pad LED cover is very bright, the numbers are big. Very good price, Revain $115 compared to other locks ($150-195). Good quality and design. There is no site address for installing videos on Revain. I think the manufacturer or Revain needs to provide the address of the Vedio install location. The address is in the instructions in the box!.
