Yale Replacement Rim Cylinder, 6 Keys Provided, P-Polished Brass, Suitable for 38-57 mm Doors

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.

all in one quick lock change with 3 additional keys..

The lock itself is nice and installed well in my application. The lock works smoothly and meets all expectations. The only downside is that I need more than the six keys that came with it and I cannot seem to get blanks for this lock in the U.S. I've tried ordering from several UK based lock sites and the site either won't give me a price on shipping, or the site just won't work. If you don't need more than the six keys that come with it, or if you're located in the UK then you're good to go.

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

I wanted a lock with a Standard Yale keyway. This lock is useless!!!

Not sure if my reviews are now aging out now -- I would have sworn I had reviewed this before, but...Inheriting a door with a Yale variant of the style of lock whose urban market was dominated by Segal for a years, only wanting to change the cylinder, I discovered that non-Yale cylinders could not be made to work -- there are multiple incompatibilities with the more usual cylinders, possibly deliberate, and jury-rigging one mismatch exacerbates others. So, get the right cylinder! I assume a person skilled in picking locks would go through this cylinder like butter but if the security is adequate for you then this is an excellent value which comes with lots of spare keys -- and if it's not, you are doubtless going to replace the entire lock.
