Lock changing in Westminster

Changing a lock can make sense even when it still works: you may have moved in, lost a set of keys or no longer know who holds copies. PrimeKey London provides lock replacements for residential and commercial doors. The choice depends on the existing hardware, the door and the reason for changing it.

When to call us

  • You have moved into a property with an uncertain key history.
  • Keys are missing and you are concerned about continued access.
  • A worn or damaged lock needs replacement rather than repair.
  • You want to discuss a suitable upgrade alongside a planned change.

A cylinder change and a full mechanism are different jobs

On a compatible door, replacing the euro cylinder changes the keyed component without necessarily replacing the multipoint mechanism. If the handle or locking mechanism has failed, a cylinder alone may not solve the problem. Describe both the reason for the change and any existing stiffness so the quote addresses the whole issue.

Plan access before a move-in change

List the entrances you control and distinguish them from communal doors. If a landlord or managing agent is responsible for an entrance, arrange the necessary permission before booking. Call 020 3519 9290 with the postcode, number of locks and preferred appointment arrangements; hardware requirements affect what can be completed in one visit.

What happens next

  1. Identify which locks need changing

    Describe each door and say whether you have working keys. A front door with a nightlatch and a separate mortice lock involves different hardware from a door operated by one euro cylinder.

  2. Choose compatible replacements

    The existing fittings and door condition guide the options. Suitable British Standard locks or anti-snap cylinders can be discussed where appropriate, with a clear quote before work begins.

  3. Check everyday operation

    The replacement needs to work with the door, not just fit its opening. Check locking, unlocking and the way the door closes, and ask about anything unfamiliar before the job ends.

A little clarity makes a stressful situation easier.

What affects a quote?
Must every lock on the door be changed?

Not automatically. Explain which keys are missing or whose access you want to change. Each lock can then be considered against that purpose and its condition.

Can a lock change be completed the same day?

Many common replacements can be completed the same day, depending on availability, the hardware required and the door condition. Confirm the arrangements when you call rather than assuming a particular timescale.

Should I book a change if my key is just becoming stiff?

Ask for the fault to be assessed first. Wear may justify replacement, but a door alignment problem can make a sound lock difficult to operate too.

Locked out or unable to secure your door?

Tell us your postcode and what has happened. We will discuss availability and the next step.
