Yale 05/501000/SN - Linus® Adjustable Cylinder Silver [Energy Class A+]

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.

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 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.

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

Working. I using half year & ok

See my other review of the linus lock for most info, but this is super simple to put together for most size locks and install ready to attach the linus. Also more secure as there is an extra screw direct through the linus template into the lock barrel, so it can't come off.

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 🤦
