Yale door cylinder
Very good item, perfect fit, i watched youtube videos to know how, was very easy to fit, just make sure you have a suitable tool for cutting the metal bar as you will have to cut this to the correct length (i used my old one to measure. Brilliant it comes with 4 keys that fit perfectly

Yale P-6KP1109-CH Replacement Rim Cylinder, Suitable for 38-57 mm Doors, 6 Keys Provided
This arrived two days after ordering so I was very impressed. As described good price considering you get 6 keys some other brands only came with two. My only slight issue was I prefer the old style rounded brass keys as they feel stronger & alittle more robust. These keys are fine though and they all worked fine when tested. I got someone to fit mine but otherwise I would of tried doing it myself as it was pretty straightforward and no cut was needed. Why pay someone £35 or more when you can just buy one and fit it yourself. Plenty of videos on YT to watch.

Easy Replacement for a Sticking Yale – Smooth Upgrade
Replaced a sticking old Yale with this and found the swap straightforward. Fit was clean, no fiddling required, and it lined up well with the existing setup. Feels smooth and secure in use — a definite improvement. If your old night latch is getting stiff or unreliable, this is a solid, hassle-free upgrade.

great all around
it worked on an old Yale lock like a charm (though the stem and screws are a bit long, must be things are thicker in U.K. than in U. S.), love the oversized keys. Beat the shipping speed to DC by half, would be happy waiting for much longer.

Didn’t line up with my hardware
Didn’t fit well in my door mechanism. Screws were too long making it a loose fit
