    Mechanical lever lock

    Posted by Tyler Coviello on Dec 4th 2024

    This Dormakaba Simplex LR1041 Pushbutton Cylindrical Lever Lock is a great option for homeowners looking to upgrade their home security without the hassle of keys. The combination entry/passage function allows you to set a custom code for easy access, while the key override feature provides an extra layer of security. Installation was a breeze, and the lock itself feels sturdy and well-built. The keypad is easy to use, even in low light conditions. However, I did find that the buttons can be a bit stiff at first, but they loosen up with use.
