05/501000/SN - Linus® Adjustable Cylinder Silver

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.

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

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.

A good cylinder to go with the smart lock and fits a wide range of doors. Instructions clear and easy to follow.

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

I use this with nuki smart locks so additional keys are no issues as I don't use keys, not sure why people bought this and need all these extra regular keys but sounds like they bought the wrong thing. This is easy to install and gives you the versatility to get your smart lock to sit nice and flush to the door without even having to measure your existing cylinder until you're ready to do the job. But that same versatility is also it's downfall, after a couple of months use, the screw holding the internal spacer is constantly working lose. I went for this as I knew it had the emergency function and would definitely fit whatever size I needed but if thread lock doesn't help then I may need to put a good old one size only cylinder in and keep this for a spare universal cylinder if anything goes wrong with any other cylinder. Just for your information, if you are buying this and need lots of extra keys, you are buying the wrong thing, this is to be used with a smart lock and the idea of those is to get rid of the need for traditional keys, I have a fingerprint reader and keypad, not a tonne of keys 🤦

used this to work with the Nuki Smartlock and it worked perfectly. Very easy to install and adjust and allows the master key tow ork on the outside even when connected to the smart lock.
