When should you consider replacing a lock?

Replacement may be appropriate when a lock is worn, damaged or no longer meets the property’s needs. New locking hardware may also be required when a door is replaced or the use of a space changes.

If your keys are lost or you have moved into a new home, it is worth reviewing who can access the property. Replacing the entire lock is not always necessary: rekeying or changing the cylinder may be an option. We assess the alternatives based on the existing lock.

Choosing a lock that fits your door

The door’s material, thickness, construction and existing hardware all affect the choice of lock. Everyday use matters too: a home entrance, a business entrance and a shared access door may have different requirements.

We install locks in wooden, metal and glass doors where the door’s construction allows a suitable solution. Compatibility is checked before installation. Not every lock fits every door, and some installations require changes to the door or other locking components.

What does lock replacement or installation involve?

We begin by checking the existing hardware and agreeing on the parts and scope of work. For a replacement, we remove the agreed components and fit the new lock or hardware. For a new installation, we also assess the fixings and any modifications required.

After installation, we check how the lock, strike plate and door work together. We test opening, closing and locking, and explain how to use the new lock.

Replacement, repair or rekeying?

If your existing lock is sticking, servicing or repair may be enough. If you want to stop old keys from working, rekeying may be possible, depending on the lock.

Replacement is worth considering when the mechanism is damaged, suitable spare parts are unavailable or you need different features. We explain the options so you can choose the work that suits your situation.

How much does lock replacement or installation cost?

The price depends on the selected lock, required components, door construction and scope of installation. Any modifications, your location and the timing of the visit also affect the total cost.

When requesting a quote, describe the door and explain why you want to replace or install the lock. Mention the existing lock’s make or model if you know it. We agree the work and price before starting. Any additional work is agreed separately, and a receipt is provided.

Lock replacement and installation FAQs

Should I replace the lock after moving home?

It is worth reviewing access if you do not know who holds keys to the property. Rekeying or replacing the cylinder may be sufficient instead of changing the entire lock. The options depend on the existing hardware.

Can you fit a new lock to an old door?

Often, yes, but compatibility needs to be checked. The door’s construction, dimensions and existing hardware determine the options and whether modifications are required.

Do you install locks in metal and glass doors?

Yes, using solutions compatible with the door’s construction. We assess installation options and the required components for each property.

Does the entire lock always need replacing?

No. Depending on the problem and the lock’s design, replacing a cylinder or lock case may be enough. We assess which components need changing.

Can I choose the lock before booking installation?

You can tell us your preferred model, but compatibility should be confirmed before purchase. We can help assess whether the lock suits your door and intended use.

What should I check before changing a lock in a rented flat or housing company property?

Check any required approvals and locking system requirements with your landlord or property manager before booking. Let us know if the door is part of a shared key system.
