Locked out of your home: what to do first

Check for danger, find somewhere safe to wait and agree the visit before help sets off.

Check whether someone is in danger

Call 999 if a child or another person inside is in immediate danger, or there is fire, violence or another immediate threat to life. Explain that access is blocked and follow the operator's instructions. Do not wait for a locksmith booking in that situation.

  • For an ordinary lockout with everyone safe, contact a locksmith rather than the emergency services.
  • Wait somewhere safe; ask a trusted keyholder whether a spare is available. Avoid climbing or forcing a door.

Describe the problem and agree the visit

Tell the locksmith your postcode, door type and whether the door slammed shut, the key is lost or the lock seems faulty. Confirm the estimated call-out cost before booking and an estimate for the work before it starts. Ask what you would owe if you decline the work.

  • Check any home-emergency policy before booking if it is safe to do so.
  • Ask what proof of your right to enter will be needed, especially if your documents are indoors.
  • Ask for an estimated arrival time and whether the locksmith is actually available now.

Discuss the entry options

Ask whether entry without damage is suitable. It is not guaranteed: a failed mechanism or damaged lock may need replacement. Before destructive work, ask for the reason, likely damage and revised total, and authorise the agreed work.
