If you need to install a new cylinder to a new door, you can measure the door thickness, then choose a cylinder which is slightly longer than the door thickness. For example, if the door is 50mm thick, I suggest you use 60 or 70mm cylinder. **Q: I require a 100mm lock 60mm from ext/40mm from int. will this lock meet this requirement ?** A: Yes. Our cylinder 40/60mm key/key can exactly meet your requirement ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy Lock Cylinder Replacement After Broken Key *by M***Z on 26 May 2026* Perfect fit, good quality, and very easy to replace.
