Review: Yale Assure Lock SL

I am a huge fan of Home Automation. I have Philips Hue lights, Schlage Smart Dead bolts, an egg minder which tells me which is my oldest egg in my Fridge, not to mention a piggy back that calculates the change I save. I even have both a Google Home and an Alexa although not in the same house.

Today I was able to get my hands on the Yale Assure Lock SL for review and being a huge fan of Schlage Smart locks, the Assure Lock SL was already facing an uphill battle. In my book, it sucked before it even arrived. When it did arrive I figured it would sit a week before I’d open it. But then I saw Voice Assistance and got extremely curious.

So I opened it up and was impressed by how it looked. I have seen Yale Assure locks before, my sister down in North Carolina has one, but I never bothered to check it out. It actually looked better than my Schlage smartlock, because of its simplistic yet modern design. It also was more compact which I liked as well.

So began the installation. I took off the dumb lock off my office door and began to install the Assure Lock SL. While reading the instructions something I hardly do. I noticed something the Yale Assure Lock SL could be powered by a 9-Volt battery by two prongs on the bottom of the keypad.


I had to remove my Schlage smartlock from my front door. My wife lost her key and didn’t realize she lost it, so to make a long story short. One day she got home before me, the batteries had died (I knew they were going bad it kept beeping when unlocking) and on top of me not replacing the batteries I couldn’t and she couldn’t get our Wink Hub to unlock it. (DUH THE BATTERIES WERE DEAD) Since that day it was back to Dumb lock with a key…how depressing. However, with the 9-volt battery backup option, I just need to make sure my wife carries a 9-volt with her!

So off to the front door I went to install the Assure Lock.


Installation was simple, if you have ever installed a deadbolt lock before, it’s the same the only difference is you need to connect the cable from the keypad to the part of the deadbolt on the inside of the door. The only con with this vs the Schlage locks. The cable is easier to connect on the Schlage locks I have used. For some reason, you have to bend the cable connector on the Yale Assure SL to connect it. Please view pics below.

Just an FYI, the lock comes with everything you need to install. With the exception of the screwdriver and drill. But it does come with a template for the holes needed in case you do need to drill them.

If you purchased the module with your Assulre Lock SL make sure you install it prior to inserting the batteries.


Set up was easy. I have the Wink Hub 2 and Samsung Smartthings hub (samsung more for testing) and both were able to connect to it on the first try. I was worried the Wink Hub 2 would give me issues as it did with my Schlage lock. But it went flawlessly. Again as I mentioned above. Make sure you install the module above the batteries before you insert the batteries into the lock.

Daily Use:

We have only been using the lock for I would say 8 hours, but the wife loves it and if she loves it, it gets my approval. It looks great on the door. Being able to just cover the lock with my hand for it to lock is great.


The Yale Assulre Lock SL is available on Yales Website. It comes in three colors, Stain Nickle (Pictured), Polished Brass and Oiled Rubbed Bronze. I personally like the Satin Nickle and Oil Rubbed Bronze the most.

The lock will cost you from $200 – $255.90 depending on if you get the stand alone version, or with the Zigbee/Zwave module and the drive in latch.

We highly recomend this lock if you are planning to upgrade your Dumb lock!
