Easy to install and works great, really helpful to have the adjustable cylinder to make sure it fits anything

Simple to install and does the job. Also takes any guesswork out of getting the correct sized cyclinder, because you can add or remove bits (provided). Works perfectly with the Linus smart lock but this also works as a standalone lock. However if you just want a lock, there are probably cheaper options available.

So this is relatively easy to set up - but the instructions for it are not very clear at all from Yale - so I've knocked off a star from that. I have used this with the Linus 2 door lock - which I can confirm it works well with. The keys are absolutely massive however, so if you have a small cylinder size it's MUCH too big for my requirements. I haven't tried to get more keys cut - it comes with 2 - because I use it with the smart cylinder, so 2 should be okay. I think though I should just get them cut at a normal size and should be okay, since the majority of the key is for reach into the lock at it's largest value - which I do not need. In terms of security - it doesn't seem to be any different from my original keys - but it does have the emergency function required to be able to use the Linus 2 Smart Lock, which is ultimately what I bought it for. It's not that much cheaper than the more expensive security locks - but these would need a thumb turn adaptor to use, hence my purchase of this.

Excellent lock that works perfectly with my Linus L2 smart lock. Was very easy to change the size to suit my door

Good quality, robust design and easy to follow assembly/install instructions

I need a smart lock from another brand, but their cylinder broke after few times use, and I found this one, easily to assemble for any size door, quality is good, but key opening from outside is not smooth, and it doesn’t have star security, I couldn’t find any alternative option at Yale a lock with 3star rating and adjustable cylinder size, it’s working perfectly, since I have attached with my smart lock, o don’t need to use keys, the price is also very good, it fits easily on my composite door over 55mm, just Yale should work on keys.

Good quality and works with a Nuki smart lock which is a massive bonus. The only issue is that getting keys cut to fit the lock can be problematic due to the length of the key blade being very long
