Locked your keys inside your car? Stay calm, it happens to thousands of drivers every day. This guide walks you through exactly what to do, from the free checks you can do yourself, to when and how to call a professional auto locksmith in London.
Step 1: Don’t Panic – Check These Things First
Before calling anyone, take 60 seconds to walk around the vehicle and check:
All four doors – one may still be unlocked
The boot – often overlooked and frequently left open
Any open windows – even a small gap can help a professional gain access faster
Also, ask yourself: do you have a spare key at home, with a family member, or in your bag? If someone can bring it to you quickly, that’s your fastest and cheapest option.
If none of the above apply, move on to the steps below.
Step 2: Try App- or Key-Based Solutions
Modern vehicles come with built-in tools that many drivers forget about in a stressful moment.
Manufacturer smartphone apps
Many car brands. including Ford, Vauxhall, Toyota, BMW, and most EVs, offer free iOS and Android apps that let you unlock your car remotely. If you’ve already set this up, open the app and unlock from your phone. If you haven’t, note this for the future.
Hidden mechanical key blade
Almost every electronic key fobcontains a small metal key blade hidden inside the casing. Look for a release button or sliding cover on your fob. This physical key can usually unlock the driver’s door even if the fob battery is dead.
Emergency override switches
Some vehicle models have a hidden override switch for exactly this situation. Check your owner’s manual if you’re not sure, it takes less than two minutes and could save you a call-out fee.
Step 3: Know When to Call a Professional
If the self-help options above don’t work, it’s time to call in the experts. This is almost always the safest, fastest, and most cost-effective route, especially compared to attempting DIY methods that risk damaging your car.
Auto locksmiths
A mobile auto locksmith is the go-to solution for locked car keys. A qualified locksmith will:
Arrive at your location, typically within 30 minutes
Unlock your vehicle without causing damage
Cut and program a replacement key on the spot if needed
Cover their work with a warranty

Roadside breakdown services
If you’re a member of the AA, RAC, or a similar provider, contact them first. Your membership may include lockout cover or key replacement, saving you additional cost. Bear in mind, response times can vary.
Step 4: DIY Methods – Only as a Last Resort
There are online tutorials showing DIY car entry methods. We’ll be honest with you: most don’t work on modern cars, and all of them carry a real risk of damage.
Method
Works on modern cars?
Risk of damage
Coat hanger / slim jim
Rarely
High – can damage locks and weather seals
Wedge and rod
Sometimes
Moderate – can bend the door frame
Shoelace trick
Almost never
Low, but ineffective
The only genuine exception: if a child or pet is locked inside a vehicle in hot weather, breaking a window is justified. In every other scenario, calling a professional is safer, quicker, and typically cheaper than repairing DIY damage.
EV and Hybrid? Here’s What’s Different
Electric vehicles and hybrids use advanced keyless entry, but they come with specific quirks during a lockout:
Check for the hidden key blade inside your fob – most EVs (Tesla, BMW, Hyundai, Kia) have one
12-volt battery failure can prevent all doors from unlocking, even when the main battery is charged. Knowing how to jump-start the 12-volt system can get you back inside
The manual key slot on EVs is often hidden under a trim cap on the door handle. Check your owner’s manual for its location
Manufacturer apps (Tesla, BMW, Hyundai Bluelink, Kia Connect) can unlock the car via smartphone. Make sure yours is paired before you need it
If none of these work, call an auto locksmith with EV experience. Specialist tools are required to unlock and reprogramme EV keys without damaging sensitive electronics.
How Much Does It Cost to Get Keys Out of a Locked Car?
The cost depends on your car’s make, model, and the service required.
Standard car unlocking: typically £60-£120
Key cutting and programming: varies by vehicle – ask for a quote upfront
Emergency / out-of-hours callouts: some providers charge a premium; UK Auto Locksmith charges no call-out fee at any hour
As a rule: always ask for a quote before work begins, and confirm whether the price includes VAT.
How to Choose a Reliable Auto Locksmith
Not all locksmiths are equal. Here’s what to look for:
Read reviews – Check Google and Trustpilot for verified customer feedback. Consistent 4-5 star reviews with detailed responses are a strong signal of reliability.
Check for a warranty – A trustworthy locksmith will stand behind their work. Look for at least 6-12 months’ warranty.
No call-out charges – Legitimate locksmiths are transparent about pricing. Be wary of those who quote low and inflate the bill on arrival.
Response time – In an emergency, 30 minutes or less is the benchmark for a London-based locksmith.
Specialist equipment – Modern vehicles require specialist diagnostic tools for key programming. Ask whether they carry the right equipment for your car brand.
Prevention: How to Avoid Getting Locked Out Again
Once you’re back on the road, take five minutes to put these habits in place:
Get a spare key cut and keep it at home or with a trusted person – never hidden on the car itself
Save your locksmith’s number in your phone before you need it
Set up your manufacturer’s app and test if it works with your car
Replace your key fob battery annually, or at the first sign of reduced range
Make it a habit to physically check that you have your key before closing the car door
Technically yes, but it's not recommended unless it's a genuine emergency. Most DIY methods don't work on modern vehicles and carry a real risk of causing expensive damage to door frames, seals, or locks.
A well-equipped mobile locksmith in London should reach you within 30 minutes in most areas. UK Auto Locksmith guarantees this response time across London and Greater London.
No. a Trained auto locksmith uses specialist tools designed to unlock vehicles without scratching paint, bending frames, or breaking seals. This is one of the key advantages over attempting DIY entry.
In most cases, a mobile locksmith is significantly cheaper and faster than a dealership, particularly for key cutting and programming. Dealerships often require the car to be towed to them, adding recovery costs.
