Yale B-YS3-3535N Anti-Snap 3 Star Euro Double Cylinder, High Security, 35:35 (70mm), Nickel Finish

I purchased the Yale B-YS3-3535N Anti-Snap 3 Star Euro Double Cylinder from Yale to upgrade the security on my door, and I’m happy with the quality. The lock feels very solid and well-made, and the nickel finish looks clean and modern. Installation was straightforward and only took a few minutes to replace the old cylinder. Once fitted, it works smoothly and the key turns easily without sticking.

This is a quality item and an easy replacement for the original cylinder. In order to fit it you will need to remove the door handles ( two bolts) and insert the Yale cylinder from the external side of the door. Be aware that the barrel of the lock should not protrude out of the door handle bezel externally so you will have to account for that in your calculations. The measurement shown for this item (50:40) is external 40, internal 50.

Good quality, easy to fit, easy to use, good security

No problem with the seller. Lock easy to fit but as others have remarked the key isn’t easy to locate quickly in the lock.

Excellent product at a fair price with prompt delivery. Exactly what I wanted.

Great quality with 3 keys. Decided to replace my locks after seeing a video of how easy it was to snap a basic cylinder lock. 3 star Yale with Kite Mark was recommended in the video, so I removed my current lock (also shown how in the video) measured it and bought this much more secure replacement. Very happy! Thank you Yale ⭐️⭐️⭐️⭐️⭐️

I've been using the three star Yale barrells whenever I need to replace a lock They are good quality and easy to fit. They fit perfectly each time. It looks as though the new version doesn't have the bump on the profile so you don't have to take the door handles off to fit, which is a good development. Happy with these and will continue to buy.

Great product. Fast to install and lovely smooth lock and unlock action unlike the cheap locks. Have great sense of security now I’ve upgraded to these high quality locks

Good quality

Lo mejor, todas las certificaciones de seguridad que tiene por su precio y la facilidad de instalación. Lo peor, que no tiene doble embrague (poder abrir aunque la llave esté metida por dentro), que cuesta a veces un poco meter la llave, y qué parece que puede ser fácil de doblarse.

Its probably a great lock but wasn't any good for my yale quattro 3 point locking set up

Muy buen producto

Belle construction du cylindre, en revanche il n'est pas débrayable contrairement à ce que la description peut laisser penser, et la clé fait franchement cheap...
