Wafer locks are widely used in vehicles, cabinets, and low-cost enclosures. Their popularity comes from ease of manufacture and low cost rather than security.
Over time, manufacturers have introduced tighter tolerances and anti-manipulation features, but the fundamental design remains relatively weak compared to pin or disc-based systems.
Despite this, wafer locks persist because they are often part of a layered security model rather than a single point of failure. In many applications, they act as deterrents rather than absolute barriers.
Understanding where wafer locks are appropriate — and where they are not — is essential for realistic security planning.
