YOUR LOCK REPLACEMENT ENQUIRY
Plan your lock replacement work
Changing keys, replacing a damaged cylinder or improving security? Request a lock replacement quote with the door type, existing hardware and required specification.
What to include in your enquiry
- Which locks need replacing and why
- Door material and any lock markings you can read safely
- Keying requirements and whether matching keys are wanted
- State whether you own, rent or manage the property and who can authorise this lock replacement work
What should the quote cover?
Specify the product, fitting work, supplied keys, old-part disposal and any adjustment. Ask the business to explain compatibility and evidence for a claimed security standard; no guide can verify a product from a vague description.
Will any replacement cylinder satisfy my insurer?
Check the actual policy requirement and proposed product evidence. Do not rely on a general claim of being insurance approved or on a product looking similar to the old one.
Property and responsibility checks
Give the insurer’s actual specification where relevant. Police security guidance is useful background, but neither this site nor a product label confirms cover or a particular provider’s credentials.
- Identify the actual property, asset and owner before commissioning changes
- Include relevant plans, reports or permission information; do not assume approval
- Agree access, protection and making good where the work affects retained surfaces

Why change a lock?
Quick answer
Changing keys, replacing a damaged cylinder or improving security? Request a lock replacement quote with the door type, existing hardware and required specification.
Request a quote to replace a worn lock, change cylinders after moving home or update a lock after keys are lost.
Lost or unreturned keys, a failed component, damage after a break-in or an unsuitable security specification can justify replacement. These are different reasons and may lead to different work. Explain whether you want to prevent an old key working, correct a mechanical fault or improve resistance to attack. An upgrade should suit the whole door and frame. A new lock cannot compensate for poor hinges or rotten timber, and an entry problem may need alignment work as well as replacement.
| Purpose | What the proposal should address |
|---|---|
| Prevent use of a missing key | Which entrances or managed systems still use that key? |
| Restore operation | Is the fault in a cylinder, mechanism or surrounding door? |
| Improve security | What compatible specification is proposed for the complete entrance? |
Lost keys and a change of occupier
If you cannot account for all copies, discuss changing the appropriate keyed component. Mention linked locks, communal doors and any restricted or managed key system. A tenancy or managed building may impose arrangements for authorisation and key supply, so check directly with the relevant person. Do not send key photographs or identifying security details through this form. Record who is to receive the new keys and how obsolete copies will be dealt with. Replacement should give legitimate occupants reliable access without bypassing agreed management arrangements.
Cylinder or complete lock?
On some doors, a cylinder can be changed while the rest of the locking mechanism remains sound. Other failures involve the case, latch or multipoint gearbox. Ask the locksmith to identify the component and explain why that scope is sufficient. The new cylinder must be the correct size and compatible with the handle and door; appearance is not enough. A complete mechanism replacement should also account for the keep positions and normal operation. Do not assume every lost-key job needs a new door.
Ask for separate prices where there is a genuine choice between retaining a sound mechanism and replacing more of the system. The cheaper option is useful only if it achieves the intended function and security. Conversely, replacing serviceable hardware may add cost without addressing door movement. A written proposal should explain the choice and any limitations, including unavailable parts, unsuitable surrounding material or a need for other repair work before the new component can be fitted reliably.

Insurer requirements and the complete opening
Check the actual insurance terms and ask which documented lock specification meets them. A more expensive cylinder does not correct every weakness in a door, frame, hinges or fitting. Request the product identity, compatible installation and any making good in the quotation; our enquiry service does not endorse a particular lock or contractor.
Timber, composite and protected doors
Identify the door and existing lock before ordering a replacement. Fixing position, thickness, frame condition and how the door must open from inside affect compatibility. Ask whether repair or a correctly fitted component can provide the intended result without unnecessary loss of sound fabric.
Keys, exit arrangements and access needs
Consider how the door is used from inside as well as outside. Tell the professional about household mobility needs, children and any required escape arrangements. The right approach depends on the door, property use and applicable requirements; do not add a lock that obstructs an essential exit. Ask how spare keys, restricted copying or a thumbturn affect the chosen arrangement. Discuss these directly with the installer rather than requesting a product solely because it has the highest advertised rating. Demonstrate ordinary use before accepting completion.
What should this quotation actually cover?
What to confirm
Specify the product, fitting work, supplied keys, old-part disposal and any adjustment. Ask the business to explain compatibility and evidence for a claimed security standard; no guide can verify a product from a vague description.
Give the insurer’s actual specification where relevant. Police security guidance is useful background, but neither this site nor a product label confirms cover or a particular provider’s credentials.
- The precise replacement part and why it is appropriate.
- Who can approve the work and receive the keys.
- Normal operation, exit arrangements and completion records.

After fitting the new lock
Check every supplied key and normal operation from both sides, where appropriate. Ask for the product details and retain the invoice. Store spare keys securely and avoid labels showing the property address. If other locks remain on an old shared key, establish whether the change achieves your intended security goal. Report stiffness or alignment problems promptly rather than forcing the new hardware. For planned work, send a clear enquiry including the postcode, door type and reason for replacement.
