Commercial lock security has different requirements from residential. Multiple staff, contractors and suppliers create key control problems that standard locks were not designed to manage. Here is what South London businesses actually need.
Commercial Security Has Different Risks
A home has one or two occupants who know each other. A business has multiple staff, contractors, suppliers and visitors — all with different access needs and all creating different security exposures. Managing this correctly requires a fundamentally different approach from residential lock installation.
The Key Control Problem
In most small businesses without a managed system, key control is informal and deteriorates over time. Keys are cut when the business moves in. More copies are made for new staff. Some are returned when staff leave; most are not. Within two or three years, an unknown number of people hold working copies of keys to your premises.
**Solution:** Restricted-profile cylinders with a patented key profile. Duplication requires an authorisation card held by the business owner. Once fitted, keys can only be cut by the installing locksmith with the card present. This eliminates the key duplication problem entirely.
Access Control by Role
Not all staff need access to all areas. A server room, cash office, stock room or confidential file store should have different access permissions from a general office. This is achieved through:
For businesses with more than 8–10 staff, electronic access control becomes practically superior. The cost of entry-level keypad systems has fallen significantly. An audit trail — showing who opened which door and when — is particularly valuable.
Staff Departure Protocol
When any staff member with key access leaves — particularly someone with access to sensitive areas — the correct security response is:
1. Recover all keys issued at departure
2. If there is any doubt about complete key recovery, change the relevant cylinders immediately
The cost of a cylinder change (£55–£85) is trivially small against the cost of a break-in or theft. Most businesses do not do this consistently and regret it.
Emergency Access
Every business needs an out-of-hours emergency access plan — for alarm activations, burst pipes or urgent supply deliveries. TrustLock should be on your emergency contacts list alongside your alarm monitoring company.
