In a managed centre the shopfront is the least of a tenant's problems. It faces a monitored mall, it is covered by cameras, and anything happening at it happens in front of people. The doors that actually protect stock are behind it — the stockroom, the back-of-house entrance onto a service corridor, and whatever cupboard holds the cash point — and those routinely carry the hardware that came with the unit.
That is where our recommendations concentrate. The door between a stockroom and a service corridor sits in a part of the building no customer ever sees, and a dozen neighbouring tenancies send staff through that corridor perfectly legitimately every trading day. A builder's cylinder is not the right answer on it. The upgrade is narrow, specific and cheap, and it is the one piece of hardware in a leased unit that consistently repays the money.
The second recurring item is what happens at handover. Units here change tenant, get refitted and get reconfigured constantly, and the cylinders very rarely change with them. An incoming business inherits access held by a previous tenant, their staff, their shopfitters and their cleaners — none of it recorded and none of it recoverable. Changing the locks before a fit-out finishes is the cheapest certainty available in this precinct.
