The door closes. You reach for your keys. They’re not there.

It’s dark. It’s cold. The shops are closed. Your phone might be in there too. A night lockout is more than inconvenient—it can feel genuinely frightening. For other emergency situations, see our guides on door jammed and key snapped in lock.

The short answer

Stay calm and assess your situation safely. Check all entry points before assuming you’re locked out. Contact someone who has a spare key. If no other options exist, a professional locksmith can help. Never attempt dangerous entry methods or trust unsolicited “help” from strangers.

First Response: Assess Before Acting

The moment you realise you’re locked out, adrenaline kicks in. Your first instinct might be to try forcing something. Resist this.

Stop and Think

  • Where exactly are your keys? Might they be in a bag, jacket, or pocket you haven’t checked?
  • Is there any chance the door isn’t actually locked?
  • Are all other possible entry points definitely secured?

Check All Entry Points (Carefully)

Walk around your property and check:

  • Back door
  • Side doors
  • Ground-floor windows (if safely accessible)
  • Garage with internal access to house

For window security tips, see our dedicated guide.

Important: Only check entry points that are clearly safe to access. Don’t climb, balance, or reach through anything. Don’t break anything.

Secure Your Immediate Safety

Before solving the key problem, address your safety.

Find a Safe Place to Wait

If you can’t get in immediately, you need somewhere safe while you figure it out:

  • A neighbour you know
  • Your parked car (if you have keys)
  • A 24-hour business nearby
  • A well-lit public area

If Your Phone Is Trapped Inside

This complicates everything. Options:

  • Knock on a trusted neighbour’s door to borrow a phone
  • Walk to a nearby business that’s open
  • Find a public phone (increasingly rare but still exist)
  • If you’re in danger, approach any open business for help

Who Holds Spare Keys?

Think through everyone who might have a copy:

  • Partner, family member, flatmate
  • Parents or siblings
  • Trusted friend or neighbour
  • Work colleague (if you exchanged keys)
  • Your landlord or letting agent

Making Contact

If your phone is accessible, start working through your contacts. Be prepared for:

  • People not answering at night
  • Time needed for someone to come from distance
  • The awkward conversation about borrowing keys at midnight

Landlord and Letting Agent Considerations

Tenants: Your landlord or agent may have spare keys and an emergency protocol. Check your tenancy paperwork or saved contacts for emergency numbers.

What Not to Do

In desperation, people sometimes make risky decisions. Avoid these:

Don’t Attempt Risky Physical Entry

  • No climbing to upper windows
  • No breaking glass (injury risk, expense, and you’ll be cold)
  • No forcing flimsy doors (you’ll damage them and still be outside)

These actions can cause injury, significant property damage, and potential alarm triggers or police involvement.

Don’t Accept “Help” from Strangers

Unfortunately, criminals sometimes exploit people in vulnerable situations:

  • Someone offering to “help you break in”
  • Anyone who just happens to know a locksmith
  • People being overly interested in your situation

Don’t Leave the Property Unsecured

If you’ve found an unlocked window and climbed in, secure it properly afterwards. An easy entry for you is an easy entry for anyone.

Getting Professional Help

When self-help options are exhausted, a locksmith is the professional solution.

Finding a Legitimate Locksmith

At night, you need someone reliable:

  • Check reviews if you have internet access
  • Use a recognised directory or professional body listing
  • Ask for identification before allowing work
  • Get a quote before agreeing to proceed

What to Expect

A competent locksmith will:

  • Arrive in a reasonable timeframe
  • Ask for identification or proof you live there
  • Explain what they need to do
  • Provide a clear price before starting
  • Use appropriate entry methods
  • Leave you with working locks

Costs to Expect

Night and emergency rates typically cost more than daytime appointments. This reflects the unsociable hours and often the journey involved.

While You Wait

If help is on the way but you’re waiting:

Stay Warm

  • Keep moving gently to maintain body temperature
  • If you have access to a car, sit inside with heating on
  • A neighbour may offer you a waiting spot

Stay Alert

  • Keep your phone charged if possible (ask to borrow a charger)
  • Note your surroundings
  • Trust your instincts—if something feels wrong, move

Stay Calm

Easier said than done, but panic doesn’t solve problems. Focus on practical next steps.

After You’re Back Inside

Once in, take steps to prevent a repeat:

Immediate

  • Make a spare key
  • Identify your key loss pattern (always losing them in certain situations?)
  • Check whether you need to re-secure anything opened during entry

Preventive Measures

Spare key strategies:

  • Leave a spare with a nearby trusted person
  • Consider a secure key lockbox (properly concealed) - see our guide on spare key storage
  • Keep emergency contact numbers saved for future

Habit changes:

  • Designated key place at home
  • Key checking routine before leaving
  • Connected key finders (Tile, AirTag, etc.)

Special Situations

Children or Pets Inside

If children or animals are locked inside:

  • This is a genuine emergency
  • Call emergency services if there’s any health risk
  • Be clear about the urgency when contacting a locksmith
  • Don’t panic—help is available

You’re Not the Property Owner

If you’re locked out of a rental:

  • Your landlord or agent may have emergency access
  • Keep their contact details in your phone
  • Check tenancy for emergency procedures
  • Document everything for deposit protection

The Lock Is Actually Broken

If the lock has failed (not just that you lack keys):

  • The same principles apply for getting help
  • This may be covered by home insurance
  • Keep evidence of the failure
  • If a key snapped in the lock, don’t force it

Prevention Is Better Than Cure

One night-time lockout is enough for most people to take prevention seriously:

  • Create spare keys now, before you need them
  • Establish trusted people who can help in emergencies
  • Save emergency numbers where you can access them
  • Build habits that prevent key loss

A few minutes of preparation replaces hours of cold, stressful waiting in the dark.
