1. Make sure everyone is safe first
If a child or vulnerable person is alone inside, something is cooking, a tap is running or you feel unsafe, call 999 straight away. The emergency services can get in far faster than anyone else in a real emergency.
Otherwise, get somewhere warm, dry and well lit, such as a neighbour’s, your car, or a café or shop nearby, and keep your phone charged.
2. Try the quick, safe checks
- Check every other door, including back doors, patio doors and the garage, in case one was left unlocked.
- Think about who has a spare key: a partner, housemate, family member, neighbour or key safe.
- If you rent, call your landlord or letting agent. Many keep a spare key, and some have an out-of-hours number.
- In a block of flats, the concierge or managing agent may be able to help with communal doors.
- Don’t climb in through a window, especially upstairs. Injuries and broken glass cost far more than a locksmith.
3. Don’t force the door
Shoulder-barging a door or levering the frame rarely works on modern doors and often breaks the frame, the lock or the uPVC mechanism. That turns a simple, damage-free opening into a repair. A locksmith can usually open a standard nightlatch, or a uPVC door that has only been pulled shut rather than key-locked, without any damage.
4. Call a local locksmith, and ask the right questions
Have your postcode ready and describe the door (wooden, uPVC or composite) and the lock if you can. A photo sent on WhatsApp helps. Before agreeing to anything, ask:
- What will the total cost be, including any call-out? Get a price or a clear range before anyone sets off.
- Will you try non-destructive entry first?
- Roughly how long until you arrive?
- Are you a real local business with a registered company name?
5. Have proof that you live there
A responsible locksmith will check you are entitled to enter before opening the door. Photo ID with the address, a utility bill or a tenancy agreement (often on your phone, or inside once the door is open) is usually enough. If authority can’t be confirmed, the door isn’t opened: that protects you too.
How to avoid rogue “locksmiths”
Some national call centres advertise very low headline prices and then add charges at the door. Warning signs include:
- A price that sounds too good to be true, with no range given.
- Refusing to give any price until they arrive.
- Drilling the lock straight away, without trying non-destructive entry.
- No company name, no local presence, or a card machine showing a different business name.
After you’re back in
- If your keys were lost or stolen, consider changing the lock or cylinder, especially if your address could be linked to them.
- Get a spare key cut and leave it with someone you trust, or in a good-quality key safe.
- Check your home insurance: many policies include home emergency cover that can pay for a locksmith.
Common questions
How much does it cost to get back in?
A straightforward non-destructive lockout opening is usually £50-75. High-security or double-locked doors cost more, from £120. The price is always agreed before work starts.
Will the locksmith damage my lock?
Not usually. Most standard lockouts can be opened without damage. If a lock is high-security, double-locked or faulty, a different method may be needed, and this is explained and agreed with you first.
Can a locksmith help at night?
Yes. Calls and WhatsApp messages are accepted 24/7 across Harrow and west London. Arrival depends on where the engineer is, so you get a realistic estimate when you call.
