Quote: door upgrades, cylinders and locks
E.g.: Replacing a cylinder after losing a key, burglar-resistant reinforcement of an existing door.
State the problem: faulty locking, keys no longer under your control or improved protection. Identify parts to retain. This enquiry concerns the existing door; complete replacement with a security door set should be a clearly separate alternative.
Assess the door before accessories
Have leaf, frame, fixings, hinges and locking assessed. Police advice mentions a crossbar or additional lock to improve an existing door. This does not show that every accessory suits your support.
Define key-control needs
Distinguish mechanical repair from regaining control of access. State functions to retain and ask about key-copy conditions, number supplied and required documents. An ownership card alone does not describe the resistance of an entire door.
Check compatibility and evidence
Request references, adaptations and component documentation. If classification of the upgraded assembly is claimed, identify the document and covered configuration. Neither transfer component classification to the entire door nor assume existing-door upgrades can never be documented.
Preserve other functions
Check effects on use, escape and any technical door performance. For shared-building doors or doors subject to requirements, clarify permissions and constraints before alteration. Request an operating demonstration at handover.

Frequently asked questions
Does a new cylinder secure the whole door?
It addresses one component. Have the other elements and intended result assessed.
Do more locking points always mean more protection?
Their number does not replace whole-assembly assessment and evidence.
Must everything be replaced after lost keys?
Assess access control and compatible options. Complete replacement is not universally prescribed.
Are extra keys included?
Ask how many and the cost or conditions of future copies.
