Would not buy again.

The lock set was missing the tumbler which is an important part of the operation. When the product arrived I saw a "Nellis" sticker on the box and I immediately was concerned it going to be missing something. Because my locksmith was already into the installation when it was discovered the tumbler was missing. My locksmith is ordering me the tumbler which is an extra expense.

This is our 3rd trilogy lock. Works great until the keypad wears out. Not a heavy duty lock, but good for occasional traffic.

The lockset is well constructed and the finish holds up well over time. This is our fifth unit for our building and I have found them to be quite dependable.

This was installed by a locksmith on our rear office door which is always locked and not frequently used. We didn't need scheduling or an audit trail just an easy secure way to get in with no key. Programming was quick and easy for under 20 codes. The only issue we ran into was a stripped screw while putting on the battery door so we had to drill and tap it and install a larger screw.

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!

This is the second trilogy I have purchased. There are some way cheaper options there but trilogy beats them all with the quality. I hire a locksmith to install it both times. It only costed $150 and it is beyond my ability to install this. After the installation, it made my office look very nice.

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.
