Securitron DK-26SS Digital Keypad Entry System - Single Door Standalone Access Control for Home & Office Security | Easy Keyless Entry Solution for Front Doors, Garages & Commercial Buildings

These are a great solution for DIY maglock systems. I purchased and installed these on all of my locations. Relatively easy install (if you follow instructions and understand how these things generally work). Definitely recommend powering through a surge protector to avoid damage to the unit in the event of a power outage.
