Clé Securemme

Securemme is an Italian brand of key with a large footprint in Britain. Generally, you’ll find one of their locks in a high-security domestic front door. Most of these keys are dimple keys, usually with a black plastic top. They have holes/dimples drilled into the stem.

They also manufacture double-bitted keys, which look like Chubb keys, but with two blades. These are most often made entirely of metal, though some models have a coloured plastic handle.
