GoKeyless™ is a factory trained and authorized Alarm Lock Trilogy dealer. Sales, service, support, valid warranties. It's why thousands of clients around the world choose GoKeyless™ for their security and access control needs each year.

In fifty years electronic locks will be considered the single most game-changing technology in terms of security for helping businesses manage access. Prior to electronic locks companies re-keyed and replaced locks when a key went unaccounted for, or an employee moved on. Before electronic locks you couldn’t deny access based on time of day, keep a record of lock activity, or require two forms of authentication at the lock. The Trilogy PDL3000 electronic keypad and card lock is a true force for solving the most critical access and security problems businesses face. With its tank-like construction, timed lock/unlock, audit trail, multi-factor identification option, scheduling, and the ability to use a hand-held DTM Data Transfer Module to upload your user schedules from your computer, the Trilogy PDL3000 is among the best electronic locks driving the change away from keys.  Projecting power and protection, this proximity card lock shows everyone you take your security serious.  The use of this technology is also smart financially.  Picture it, no more hunting down keys, making new ones, or servicing locks. Above and beyond the money you’ll save, the PDL3000 comes with advanced programming options that’ll make you feel like the flight director at mission control.  Need commercial grade?  Don’t want to mess with wiring?  Then this lock is precisely what you’re looking for.  Made by the US based company, Alarm Lock, the PDL3000 powers your access control with codes and HID proximity cards(or any 125khz [common] card) or fobs. (sold separately at checkout)  In no time, you can change and delete users when you need to.

  1. Frank Licari (verified owner)

    The lock itself works very well. I was able to program it manually with little problem following the manual and it does the job perfectly.
    However, the CD-Rom that it comes with in order to hook up the computer, gave me problems installing. The link that I was sent also has given me issues. I will be retrying to install it this week so that I can get reports from the system but this particular part was not easy and user friendly.
    But overall, the lock itself works very well and we are pleased with the performance.

    Great lock. Love the Keyfob entry. Computer connection was a bit tricky to get going but tech support at GoKeyless was very helpful! I called them twice during the install of the PDL3000 and they helped me quickly and efficiently both time!

Customer Questions & Answers

  1. Answered by the admin

    Trilogy does not offer any locks that are Bluetooth enabled or that integrate with Apple products. This model can be programmed directly at the keypad or from a laptop through the DL-Windows software by using the AL-PCI2u cables. 

  2. Answered by the admin

    You are able to enroll standard 128Khz proximity cards with this lock for door access. The programming for this can be done directly at the lock or through the DL-Windows computer software. The lock itself does not require any internet access and can be entirely standalone. 

  3. Answered by the admin

    The only model that would be able to accomplish this would be a Networx Panel with two NetPDK keypads wired in. Otherwise, a code would need to be entered at both doors to begin the unlock schedule. 

  4. Q Does the access history remain for every access? answer now
    Asked by Roy on March 1, 2019 6:47 PM

    It has a 40,000 event audit trail and it will overwrite the oldest audit once it reaches 40,001 and will keep the next 40,000 events, etc. 

  5. Q What is the low battery alert? How do you change the battery? answer now
    Asked by Jonathan on January 28, 2019 2:28 PM

    The low battery alert is an alert that lets you know the batteries are getting low and need to be changed. You change the batteries by opening the back of the lock and swapping out the five double A batteries for new ones. 

  6. A

    Yes, the key override will always work the lock regardless of schedules. 

  7. Q Can I use this lock with a panic bar? answer now
    Asked by Dianne on November 5, 2018 5:19 PM

    No, you need to purchase the ETPDL for panic bars. 

  8. A The lock will read a standard 26 bit Weigand card with a 125 kHz read range. If your current cards meet those specs then it will work in the system.
  9. A

    No, the AL-PCI2U software and the AL-PRE must be purchased separately.  

  10. A These can be installed on a gate but we would suggest silicone around the seams.
