The ICS key

Being reversible, ICS key offers two advantages at once. Inserting the ICS key into the cylinder is particularly easy due to the key's specially developed tip. The key's thickness of 3 mm and the high-quality nickel silver alloy make the key durable and resistant to wear. The depth of the three cuts on the bottom of the key are now concealed. Consequently, illegal key copies are virtually impossible, even using the most recent 3D printing methods.

The ICS design key

The ICS key are optionally available in the colours black, red, blue, white, yellow and green. The colour coding helps to differentiate between keys.

Picking and scanning protection

Split and non-split scanning elements prevent scanning positions from being detected. The ICS cylinder is practically impossible to open with lock picking tools. The hidden gates on the locking pins prevent the ICS cylinder from being scanned.

Drilling protection

The chrome-vanadium elements in ICS cylinder protect it from illegal opening methods. Additional security elements offer high attack resistance.

Plug pulling protection

The chrome-vanadium pins in the cylinder plug, combined with the steel rod in modular design (SYMO), offer high plug pulling protection.
