Cost: door upgrades, cylinders and locks
Price each intervention following assessment: cylinder, lock, reinforcement, adaptations and adjustments. Compare product references and included work, not just locking-point counts. No universal average price or fitting time is established.
Editorial update on 18 September 2026
Separate scenarios
Itemise every part and service. Cylinder-only replacement differs from adding a lock or reinforcing door and frame. Compare the same objectives and references.
Expose adaptations
Include assessment, travel, adjustment, finishes and keys. Establish charges if proposed equipment proves incompatible. Approve additional amounts before further work.
Compare replacement when needed
If the support cannot meet the objective, request reasons and a complete alternative. Upgrading is not automatically cheaper. Check insurance requirements against your contract without assuming a premium reduction.

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.
