  2. Excellent Quality

    Stephanie Chong

    Perfect with the single exception that it beeps when opening which is distracting – loose the beep and you have a perfect lock.

Customer Questions & Answers

  1. Q Programmable for free passage and how simple? answer now
    Asked by Lawrence Zarrilli on May 11, 2019 12:41 PM
    Answered by the admin

    While you cannot program it for a daily schedule you can program by hand each day to go into a passage mode and then manually program it to lock when you are done. 

  2. Q Would this work on a vinyl fence gate? answer now
    Asked by Stephanie Chong on September 4, 2018 12:01 PM
    Answered by the admin

    Yes, the lock is fully weatherproof and can be used on a gate, however, for vinyl we recommend that the gat is reinforced at the point of the install as this is a commercial lock and it weighs around ten pounds. 

  3. A You can define if you want to use 3 to 5 digit codes, however, it must stay as a 3, 4 or 5 digit code for all other codes once you have programmed it that way.
  4. Answered by the admin

    Yes this lock will work just fine being exposed on both sides as the manufacturer has weatherproofed both the front and the back of the lock to ensure usage on exterior gates.
