Locks

Most Common in EU

Warded Locks

"Uses internal wards to obstruct the rotation of incorrect keys. One of the oldest lock designs, but provides minimal security by modern standards."

Wafer Locks

"Uses flat metal tumblers to prevent rotation of the plug. Wafer locks range from low to high security, with the vast majority of wafer locks being low security."

Pin-Tumbler

"Uses moving pins to prevent rotation of the plug. Pin-tumbler locks range from low to high security. Currently the most popular lock design worldwide."

Dimple

"A pin-tumbler based design that uses a horizontal keyway rather than the traditional vertical style. High-security dimple locks have various security features that most traditional pin-tumblers don't. Namely, the use of telescoping pins."

X Locks

"This is the cruciform, or cross lock. In Europe they sometimes call it the “Zeiss” lock, after the original inventor. It’s basically four different (sometimes only three) locks built upon a single key."

Tubular Locks

"A pin-tumbler based design with pins arranged in a circle and accessible from the face of the lock."
