What makes a lock high security
- Key control: patented keys that cannot be cut at a hardware store, often only with your signed authorization.
- Pick and bump resistance: extra locking elements beyond a basic pin stack.
- Drill resistance: hardened inserts in the cylinder face.
- Testing: some are tested to standards such as UL 437.
Common examples include Medeco and Mul-T-Lock cylinders, which can often be fitted to existing commercial hardware.
Where it makes sense
| Door | Why |
|---|---|
| Pharmacy and medication rooms | Controlled substances and audits. |
| IT, server and records rooms | Data and privacy. |
| Cash rooms and safes | Obvious targets. |
| Master key systems | So the master key itself cannot be copied. |
