Yale P-YS3-4550B Euro Double 3 Star Cylinder, 3 Keys Supplied, Maximum Security, Visi Packed, Suitable for All Door Types, 45:50 (95mm), Brass Finish

Seeing how easy it is to break through a basic euro cylinder is pretty shocking. I swapped out the 0 star cylinder for this three star (the maximum rating available), it's an easy swap, 2 minutes with a screwdriver. It's clearly more secure, sacrificial snap points to stop making things easy for a burglar, as well as the keys having two slots, so anyone trying to pick the lock, would effectively need to pick two locks at a time.Just remembered to measure up properly, as these aren't all the same length.

Fitted and works fine. A good 3* door lock

Great lock easy fitting a little notchy but after applying oil better ,will no doubt get smoother with use has to bed in I guess

Fitted in my daughter's property, as the old lock was not working properly. Chose this type of lock, as it had the best security features, I could find at a reasonable price.

It has been received as expected and I am happy with the delivery.

It took only a few minutes to fit the new lock. on my wooden door I had to make a couple of drill cuts to allow for the anti bump nodules, but that was a 30 second job. these locks are easy to fit and provide much improved security against bump devices.

Need to get these to comply with your insurance - 3 star kite mark.

received this today and fitted it.I had to remove the door handles/cover plate in order to fit this. I did have to spend about 10 minutes trying to align the handle cover plate to secure the 2 screws holding the inside to outside.Now the advice was to measure your existing lock and buy the same one - which I did.My current lock protrudes on the inside by - perhaps 5mm.Anyway, the fitting instructions advise the lock barrel to be level with the handle plate....well, erm not quite on the inside!So should I have bought the slight smaller INT figure by 5mm - perhaps yes had they not plastered the advise to get the exact same one you have. I'm guessing that would have then fitted perfectly and still worked. So a bit annoyed about that, was on the verge of sending it back to get the slightly smaller one, but I didn't want the ob to take even longer.
