    Great Digital Door lock

    Jeri Murphy (verified owner)

    Installed two of these. One on each of the gates into our backyard. We’ve had them in place for several months and they have worked great. No complaints.

    Good small lock

    Barbara (verified owner)

    We used it on a gate to the backyard. Only downside was that I would have preferred a longer bar which locks it. Directions for installation were good and we have had not problems for 6 months.

    My home was recently entered by someone who had a key and they stole MAC computer. We feel we know who is was, but can’t prove it. The MAC was close to the entrance of the home and that’s all that was taken. I have a computer room with a lot of equipment and nothing was touched there. I purchased your M220 lock for the door of that room, the M220 works fine, they may get in that room, but they will have trouble doing it. Thanks for providing some security in my home. I am now looking for a remote dead bolt which I think you can supply.

Customer Questions & Answers

  1. Answered by the admin

    Yes, it can be used in that manner as long as the doors close tightly together without much of a gap. 

  2. Answered by the admin The lock itself will work on that type of fence however, you will need an extension kit for this to work. Please see the link below for the required product. https://www.gokeyless.com/product/lockey-extension-kit/
  3. Answered by the admin The Lockey M220 is a mechanical deadbolt lock. This means there are no batteries and uses push pins for its coded entry. When a valid code is entered you then turn the knob to throw the deadbolt and then must turn the deadbolt again to lock it. There is no automatic throwing feature in this lock.
