Great quality product. For the first time in 10 years, my back gate now feels secure. John from California
I've had my new lock installed for a while and I have to say I love it. I love how easy it is to unlock my apartment, and yet the safety of not worrying that someone can easily bump the lock. I know that my door is still not '100' percent unbreakable. I know that the jam is still a weak spot - but, any breakins now will leave a sign. My old lock was designed to keep an honest man honest (and this world isn't full of honest men). I've been broken into, and except for the things missing - there was no exterior sign to the door that someone came & went. (Old door with lots of past jam damage). Now - with my keyless model/ deadbolt - I feel safer. A reasonable price for security and sanity. Thank goodness! Rose from Massachusetts
Works great. And was easy to install. Thanx John from Florida
I received the lock as advertised, a very good price. It was very straight forward installation, fit and functions perfectly. Excellent value. Kevin from California
This product was not the right fit for my intended use, but GoKeyLess’s return policy worked well. The package was missing a page or 2 of the original instructions, so I couldn’t figure out how to reconfigure the lock to work on deadbolts from the right side of the door instead of just the left side of the door.

Trusted to Take Care of Your Home Security Needs
Part of the wave of innovation in home security, the M210 keyless deadbolt features a vandal-protected, rust-resistant, combination keypad, and only permits access to those who know its code. For use on doors requiring top-bolt locking, the M210 retrofits your common, everyday deadbolt. The M210 keyless lock is as strong as any lock in its class, adds value to your property, and pays for itself after a few days of use. Why go another day with keys. The M210 is suited for light traffic residential and small office entry doors where you want to control access for a relatively few number of people. Separate handles are available at checkout for opening the door. Released in the Spring of 2006, the "bump" and pick proof M210 became an immediate GoKeyless top-seller in mechanical keyless deadbolt locks. Please beware of reproductions. We only stock the authentic Digital Door Lock, not a copy.
