Alarm Lock - DL270026D Trilogy By T2 Stand Alone digital lock DL2700/26D

Built tank tough!! A little time consuming to make proper retrofit to fit on an already bored out commercial door but worth the money and time. These are awesome.

The Trilogy series locks are the only way to go if you want commercial-grade, rugged, durable high-security for your site. Hands down, the strength and weight of the materials used in this lock series cannot even be compared to anything you can get through normal 'retail' channels. This is not a 'consumer grade' lock-set; it is rated "Grade 1" and carries ISO ratings (recognized worldwide). Note: Trilogy locks require special (extra) holes in the door (compared to consumer-grade locks), but comes with a template showing how to drill the door. This lock is user-installable if you are comfortable with a drill, have the correct bits, and are adept with measuring. If not, hiring a locksmith to do the install would be wise. Programming is relatively straightforward if you follow the included manual. If you don't like the "Schlage C" 6-pin cylinder that comes pre-installed, you CAN change-out the cylinder with another type (like Medeco, Keymark, or similar). This requires no special tools; only a working key, and the "Pin" type tool that comes with the lock-set. Trilogy is absolutely the top of the line in commercial-grade security; I highly recommend this lock series!

I maintain several financial facilities, I use AL products exclusively and these locks are very reliable. Easy to install and set up. Very strong construction and the lockset is interchangeable to match your facility key system.You will like the ease of programmability, you can set multiple codes for several people, if someone leaves employment with you, simply disable their code so everyone is not affected by frequent code changes. I really do work in facility management for a financial institution and this review is real. this was a certified amazon purchase, in fact I have purchased 6-7 of these over the past 2-3 years.

I took other reviews guidance and hired a handyman…even they had trouble with what needed done to make it work. Great now that it’s installed but be prepared for some work.

Works well for my short stay rental. Change code after every guess

Purchased in December of 2024. Professional installation was done February of 2025. Bottom row of buttons stopped working after one month. Return option window closed Jan 31st, 2025. The ones we normally purchase are twice the price of the TRILOGY DL2700. It seemed like a savings at the time. Now its not usable or returnable. Plus shutting down this buildings access point is a huge inconvenience.

Quite the pain in the butt to install. There was no instructions inside the box. The instructions were hidden deep into the bottom of the page on the Amazon listings as a PDF. The company website is pretty much useless, as you have to register to create an account just to even see any documentation or obtain info.The product itself is quite solid although I wish it had a better bolt system, as it is very easy to rake with a metal hook and open if you have any gap in your door.

These are indestructible. I've been using them for years and love them. If you use Duracell batteries, you only have to change the AA batteries every 5 years or so. This is the best price I've found so far.
