There aren't many high security thumb turn euro cylinders available. This fits the bill perfectly. They key is also compact and not oversized like some of the high security cylinders. Size combinations are more limited that common or garden cylinders, but we got one to fit.

Regardless of the steel used for the key and the cylinder, the texture is better than expected.

Hello, the cylinder I have is a 35 x 35 x 70mm. It has 5 pins at lock end and 1 pin at thumb turn end. I need to know if I have to replace it with a cylinder having the same pins or can I use a cylinder with any amount of pins on my lock?
richard shimeld, derby
You will need to replace your cylinder with the correct profile and matching length but the security level, which is partly indicated by the amount of pins included, can be any. We recommend getting higher than 5 pins for an external door.

Hi, can this product be key alike to an existing lock I have?

Many thanks.
Martin, Hertfordshire
Your existing cylinder would have to be from the CISA Astral S 10 Pin Euro Cylinder Series. Each cylinder includes a code card allowing you to purchase additional keys or locks by simply providing the code to your existing lock.
