Locked Your Keys in the Car? Here's Exactly What To Do (UK Driver's Guide)

It's a familiar moment for anyone who's driven for long enough. You shut the car door, hear the satisfying thunk, and a half-second later realise something's not right. Maybe you can see your keys glinting on the front seat. Maybe they're in the boot, behind shopping bags. Maybe they're still in the ignition.

If that's where you are right now — keys locked inside, you outside — take a breath. You're not stuck. You're not in trouble. The vast majority of UK drivers will be back in their car within 30-60 minutes once they make the right phone call. This guide explains exactly what to do, in the order you should do it.

If you're somewhere unsafe — busy road, dark car park, or with a child or pet stuck inside — skip straight to "When You Need to Call Right Now".

First — Don't Panic, and Don't Force the Door

The instinct after locking yourself out is to immediately try doing something. Wiggle the handle. Push the window. Hunt around online for "how to break into your car." Almost all of it makes the situation worse.

Modern UK cars have deadlock systems that engage as soon as the doors lock. These deadlocks make it physically impossible to open the door from the outside — even by smashing a window — without a key or proper unlocking equipment. They also resist most DIY methods, including:

• Coat hangers through window seals → damages weatherstripping (£50-£200 to replace)
• String techniques through door tops → tears door seals, scratches paint
• Slim jim tools → designed for cars from the 1990s, useless on most post-2010 vehicles
• Pumping/wedging the door → bends the door frame, often permanently
• Smashing windows → £150-£500 in replacement glass, plus the deadlock still won't release

If you damage the car trying to break in, you'll pay for repairs and still need a locksmith. It's the worst of both situations.

The single best thing you can do in the first 60 seconds is take a breath, step back, and read the rest of this guide.

Step 1 — Check Every Door and the Boot

Before assuming you're locked out, physically check every door. In a stressful moment, it's surprisingly common to find one door — usually the back passenger side — was never locked. Many central-locking systems have small quirks: if you locked from the driver's side handle while a back door was open, the back door won't engage.

Check in this order:

1. All four doors — try each handle, including back doors
2. The boot — many cars allow boot access independently; if there's a key fob inside the boot you can sometimes get to it via the rear seats
3. Sunroof — if open, may give access to the door unlock button (rare but happens)

About 1 in 6 "I'm locked out" calls we attend turn out to have an unlocked door the customer didn't try. Save yourself a call-out — check thoroughly first.

Step 2 — Locate Your Spare Key

Spare keys exist for moments like this. Common places to find one:

• At home — kitchen drawer, key hook, "safe place" you'll remember in 5 minutes
• With a partner, family member, or housemate who can bring it
• At work, if you keep one in your desk
• With a friend or neighbour who has spare access

If your spare is at home and someone can bring it within an hour, that's almost always faster and cheaper than a locksmith call-out. Wait it out, stay with the car, get them to bring it.

If no spare exists or it's not retrievable — proceed to Step 3.

Step 3 — Decide: Locksmith, Roadside Recovery, or Wait

You have three real options. Here's how to choose:

Option A — Mobile auto locksmith (recommended in most cases)

• Arrives in 30-60 minutes typically
• Opens the car at your location, no damage
• Can also cut new keys if you've lost them entirely (not just locked them)
• Costs £79-£150 typically for a standard unlock
• Best for: any non-emergency lockout, anywhere drivable

Option B — Roadside recovery (RAC, AA, Green Flag)

• Included if you have membership
• Arrives in 30-90 minutes typically
• They can usually unlock cars but may not be able to handle all modern keyless systems
• Best for: members who already pay for it
• Caveat: some breakdown providers will tow the car rather than open it on-site if their on-call technician can't unlock it

Option C — Wait it out

• If the spare is on its way and you're somewhere safe
• If the parking is fine for an hour
• If there's no urgency

Avoid:

• Going to a main dealer (most won't even attempt unlocking; they'll tow the car to a workshop and charge £400-£800+)
• Calling a "general" locksmith (most non-auto locksmiths can't handle modern transponder keys or keyless entry systems — they may damage the car trying)

Step 4 — When You Need to Call Right Now

In some situations, waiting isn't an option. Call immediately if:

• A child or pet is locked inside, especially in warm weather (dial 999 first if there's any heat or distress risk)
• You're in an unsafe location — busy road, dark and isolated car park, area where you don't feel comfortable
• You're blocking traffic or causing a hazard
• Your engine is running with the keys inside (more common than you'd think)
• The keys have fallen out of reach somewhere only the technician can retrieve

For all of these, the answer is "call a mobile auto locksmith now and tell them the urgency." A reputable service will prioritise you ahead of routine jobs.

Step 5 — When the Locksmith Arrives

Whoever you call — Royale Car Keys, RAC, anyone — they'll need to verify you own the car before unlocking it. This protects you against theft and is non-negotiable.

Have ready:

• Driving licence matching the car's registration address (or a photo of your licence on your phone if it's locked inside the car)
• V5C logbook if you have one accessible — not required but speeds things up
• Any way to demonstrate ownership — a phone insurance app, an email confirmation, etc.

Stay with the car until they arrive. Don't wander off, even briefly — they need you present to verify identity.

What to Do Next Time (a 30-Second Prevention Plan)

After a lockout, drivers always say "this won't happen again." It usually does. Here's how to actually prevent the next one:

1. Order a spare key if you only have one. Spare keys cost £79-£149 at a mobile locksmith vs £150-£500+ at a dealer. A spare ordered while you have a working original is far cheaper than a "lost all keys" call-out.
2. Keep one key off your main keychain. Hide it at home (not in the car), or give a duplicate to someone you trust nearby.
3. Get into the habit of "keys-out-first" — develop the muscle memory of taking your keys out before opening the door, not after.
4. Consider a keyless-entry-related security upgrade if your car is a relay-theft target. We've written a Ghost 2 vs CAN Phantom comparison covering modern car security.

Quick FAQ

Will the AA or RAC unlock my car? Usually yes, if you're a member. They typically arrive in 30-90 minutes and unlock standard cars. They may not handle all modern keyless or transponder systems — if they can't, they'll often tow the car to a workshop. Worth confirming on the phone before they're dispatched.

Can I get into my car with a phone app? Some newer cars (Tesla, certain BMWs, Mercedes Me, Volvo, etc.) allow remote unlocking via an app — if you have it set up, the app, internet connection, and a charged phone. Check this before calling anyone.

My keys are in the ignition with the engine running. What now? Call a mobile locksmith immediately. This is one of the situations where "wait it out" isn't an option — the engine running, fuel burning, and a heated interior creates real risks if it's a hot day or the car is in an enclosed space.

A locksmith said they'd "drill the lock" — is that normal? For modern cars, drilling should be a last resort, not a first step. A reputable mobile auto locksmith will use non-destructive entry methods first. If the first thing they suggest is drilling, get a second opinion.

What if I call a locksmith and the door turns out to have been unlocked? Most reputable services charge a small call-out fee for false alarms (typically £30-£50). Worth checking beforehand.
