PrimeKey London / Westminster & SW1
PrimeKey London. A practical approach to locks.
We help with emergency access, faulty locks and considered security changes across Westminster and the surrounding SW1 neighbourhoods.

Door hardware from our existing website collection.
Clear information, considered work
Understand the fault.
Choose the right repair.
A lock is part of a whole door system. The cylinder, latch, frame alignment and mechanism all matter. We aim to explain what is wrong and the work proposed, so you can make a decision before it starts.
Non-destructive entry is considered where the lock and circumstances allow it. Where replacement is necessary, the suitable hardware and quote should be discussed first.
Our address is 25 Maunsel St, London SW1P 2QN. Please telephone before visiting; service appointments are arranged directly.

Good questions. Clear answers.
Before you call
a locksmith.
A little clarity makes a stressful situation easier.
What affects a quote?Which areas does PrimeKey London cover?
PrimeKey London covers Westminster SW1, Victoria, Pimlico, St James's, Belgravia, Millbank, Whitehall and Vincent Square, including the Victoria Station area. Give your full postcode when calling 020 3519 9290 so the property location and access arrangements are clear.
Is emergency help available at night, and how soon can you attend?
Emergency locksmith support is available 24/7. Attendance depends on the exact address, traffic and current workload, so ask about availability when you call. Round-the-clock support does not mean a guaranteed arrival within a fixed number of minutes.
Will I receive a quote before work starts?
Yes. PrimeKey London explains the proposed work and provides a quote before it begins. The lock, door condition, access problem and any required parts affect the job. Ask what is included, including any call-out, labour, parts or out-of-hours charges that apply; a final diagnosis may require inspection.
Can a locked door be opened without damage?
Non-destructive entry is the preferred approach where the lock type and condition allow it. It cannot be guaranteed for every lockout or mechanical failure. If damage or a failed component makes replacement necessary, the proposed work is explained before proceeding.
Should I ask for a repair, a lock change or a security upgrade?
Describe the problem rather than choosing a part in advance. A fault with an existing key or handle may need repair; missing keys or an uncertain key history may make a change appropriate. An upgrade concerns suitable security hardware. The same entrance can need more than one of these considered together.
What details should I have ready when I call?
Have the full address and postcode, the affected entrance and a brief description of the fault ready. Say whether you are locked out, can get inside but cannot lock up, or want planned work. Mention shared access, a responsible property contact and any permission needed. You do not need to know the lock model.
