It is the most used cylinder in locks. It features standardized sizes and dimensional tolerances to allow interchangeability in locks by different manufacturers.
An Anti-drill cylinder is provided with protective devices which make drilling more difficult and longer; these devices may be pins or internal carbonitrided elements or case-hardened steel elements.
An anti-tear cylinder is provided with protective devices which make tearing more difficult and longer.
"Bumping" is a picking technique to open cylinders. A bump key is inserted into the cylinder and is used as a tensor. The key is then knocked with any rigid object, the pins jump up and the cylinder opens.
Most of cylinders are supplied with 3 single keys. However, it is always recommended to check the article, since the same cylinder could be supplied with additional keys on request.
Some cylinders need the key in order to be disassembled. In this case, if they have a property card with a code, the key can be reproduced in a service centre even without the original. Otherwise, you will have to pick the cylinder.
Yes it is EN1303
It is a cylinder having a key which can only be used during the building stage (first-use key), and a bunch of sealed keys handed over to the end user (second-use key). The insertion of the second-use key disables the first -use key (the process is not reversible).
It is a cylinder provided with one or two bunches of sealed keys (1st, 2nd and 3rd use).
The 1st bunch is normally used to open the cylinder.
Should any of the keys in the 1st bunch get lost, security is guaranteed using a key from the 2nd bunch. The insertion of the second-use key disables the first -use key (the process is not reversible).
If a cylinder is provided with the 3rd bunch, the lock can be further recoded.
