Nuki Universal Cylinder, For Nuki Smart Lock, Highest Security Mark SKG, Emergency Function, Set including 5 Keys, Accessory For Electronic Door Lock

I love the modular construction, high quality and finish, easy to replace and set up with Nuki lock. Pricey but well worth it.

I tried another make of barrel with my Nuki lock first but it kept giving problems so bought this one which has worked just fine. It seemed expensive compared to other makes but considering you get 5 keys it more cost effective than many other cheaper options.

I like that - it’s adjustable, i can move it to different place if i need to. Left it slightly sticking out so i could install the nuki lock easier. Came with 5 sets of keys.Nothing to dislike really.

Easy install, everything in the package. The keys are good quality. Bought for use with an Aqara u200. Works as advertised. Downsides are price and the exposed logo on the front. Seems unnecessary for a lock, but most manufactures seem to do it. Would be nice to have it clean at this price though.

It’s a modular lock, that is designed for a variety of doors, sort of like Lego you can take it apart and reassemble it taking away or adding different sections or rods to adjust the size.It’s snap proof plus has a 3 star Swiss labelling which is similar to UK 3 star labelled locks.Bear in mind all locks are pick able, they are there to slow down an uninvited person or persons from gaining access so if it does slow down an uninvited person and causes passers by to look at what person X is doing that’s the job and if you need your door to be impenetrable you will need steel door frames and reinforced hinges.Anyway the lock is ok, but tricky to reassemble once you start taking bits out and fits bits in to make it fit your door, as I found that my original cylinder was a 40/45 and setting this lock to this it fell short about 10mm so puzzled by this in the end I had to add one extra section which made it sit perfectly through my door handle and anti snap shield.The lock works great, but this was my 2nd lock!The first one had a flaw, one of the hex screws was so bare that the allen key once inserted would not rotate the screw so I could in no way adjust the lock or take it apart to remove or add modular pieces.Contacted Amazon and a replacement was sent out on that day and arrived next day. Plus I sent back the faulty one asap to Amazon, you don’t want to be charged double as these cylinders aren’t cheap.

This lock is a bit expensive, but if you want further locks that are keyed alike then they are twice as expensive even though they are simpler locks which aren't adjustable size. There is no option to obtain another keyed alike £75 adjustable lock like this one.

In the first look, the cylinder looks great, high quality, with keys can’t be manipulated, but after just 5 days use, the rod that connects to the Nuki smart lock broke down, and it’s stuck, luckily I had physical key by which I could enter it, otherwise I am completely locked, it’s a great security issue, I contacted Nuki customer support on Friday evening and they replied on Monday, the price of cylinder is about 2-4 times higher than, they should have supported promptly, I think there’s serious problem in design, it should be strong metal, slight thick metal, with ending little bit larger, and they should have replaceable heads like others in market, to improve function, installation is easy, and no issues in fitting, otherwise easy to use.
