Review on 🔒 Signstek Silver Touchscreen Keypad Security Entry Door Lock with Interchangeable Left/Right Handle and Hidden Mechanical Key by Charles Collier

Great product for the price. The "randomly flashing numbers" after entering the code is 4-3-2-1, which is just lazy product programming, but it works fine for home use. The instructions are translated into some broken English, so take your time installing and programming the device, and the reset button will take you back to step one if you make a mistake. Use good quality batteries for smooth operation. Only your master code can be used to keep the door unlocked, so additional programmed codes do not have this function. I don't recommend this for a primary access point as water resistance is questionable and a deadbolt would be the best protection, but as a secondary access point like a garage door leading into a house it's perfect.
