Deter theft and ensure doors are always locked with the new Trilogy DL5200 double-sided electronic lock by Alarm Lock.  It is ironman tough, and capable of accommodating multiple users.  You will use it on gates, and openings where you need to control access on both sides of the door, such as jetways and police interrogation rooms.  This powerful electronic door lock lets you issue codes instead of keys.  You will even be able to delete users from the door in seconds.  A new electronic smart lock like the DL5200 is also a strong first-line-of-defense against private, or sensitive information being stolen or compromised.  Since user’s don’t have to worry about locating and taking their keys with them each time they leave, the likelihood of doors being left open or propped open is virtually eliminated.  If you add up the time spent issuing and tracking keys, and the expense of re-keying and changing out locks, not to mention liability costs, you will see the Trilogy DL5200 quickly pays for itself.

Perfect for community pool gates, courtyard gates, airport jet bridge doors, communicating doors, interrogation rooms, psych and Alzheimer areas, and more!

    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. A

    Yes, the Trilogy DL5200IC is the exact same lock as this but designed to work with SFIC.

  2. A

    When using default settings, the door will lock ~3-5 seconds after opening with a valid credential. 

  3. Q How do you change the battery? answer now
    Asked by Thomas on June 12, 2021 5:40 PM

    To change the battery on this model, you will need to remove the secondary side from the door. This can be done by removing the interior handle (the manual key will be required for this). Once the handle is removed, you will need to remove the 4 mounting screws. There are one above and below the handle mount and the other two are located on the sides of the unit. Once these are removed, the housing should pull away from the door revealing the battery pack inside. Simply disconnect the battery pack and exchange the (5) AA batteries that are inside before reinstalling!

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

    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. 

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

    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. 

  6. 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.
  7. A

    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.
