How Our Car Key Replacement Service Works

We combine expert locksmithing with advanced diagnostics to replace modern keys quickly and correctly. Here’s what to expect:

Confirm your vehicle details
We’ll ask for your make, model, year, fuel type (where relevant), and the situation (lost, stolen, broken, spare key). This helps us prepare the right key profile, transponder chip, and software.
Mobile dispatch to your location
Our fully equipped vans cover NW postcodes including Camden Town, Kilburn, Willesden, Golders Green, St John’s Wood, and Wembley Park. We’ll arrange a convenient visit, including evenings and weekends.
Non-destructive entry where required
If your keys are inside the vehicle, we use non-destructive entry techniques to open the car without damaging the locks, glass or weather seals. Rare exceptions—usually on heavily damaged or non-responsive systems—are explained and agreed beforehand.
Key cutting and transponder setup

Precision car key cutting: from standard to laser-cut/high-security blades.
Transponder key programming: the small chip in your key talks to your car’s immobiliser. We pair it using dealer-level OBD2 diagnostics or advanced EEPROM/ECU methods when needed.
Smart/proximity keys: we supply and program push-to-start and keyless entry fobs where supported.

Immobiliser and remote configuration
We synchronise the new key or fob with your vehicle’s immobiliser and remote locking. For some brands, we perform ECU/immobiliser programming to ensure reliable starts and locking.
Testing and handover
We test starting, locking, boot release, and any smart functions before you sign off. We’ll also show you how to care for your new key and provide warranty details.

Tools and training

Dealer-level diagnostics for BMW, Mercedes-Benz, Audi, Volkswagen, Ford, Vauxhall, Toyota, Nissan and more
OBD2 key programming for most 2010–2025 vehicles
EEPROM programming for models requiring advanced immobiliser solutions
OEM-quality or high-grade aftermarket keys and remotes
Secure key data handling and anti-theft best practices

Types of Car Keys We Replace

Standard and transponder keys for everyday models
Remote flip keys with integrated fob
Smart keys and proximity key fobs for keyless entry/push-to-start
High-security laser cut car keys
Van and commercial vehicle keys (including Ford Transit, Mercedes Vito, VW Transporter, Vauxhall Vivaro)

If your fob is intermittently working or not pairing, our dedicated service may be a better fit: see car key programming. For quick spares, you can also review car key cutting and duplication.

Lost, Stolen, Broken, or Spare: The Right Approach For You

Lost or stolen car keys
We can cut and program a new key from scratch and, where possible, delete the old keys from your car’s immobiliser so they no longer start the vehicle. For theft risk, we can advise on a quick car security upgrade.
Broken or damaged car key
If the key blade has snapped or the shell is cracked, we can often repair or replace the housing and cut a new blade, then transfer or program transponder components as needed. If the key is stuck, we offer broken car key extraction and ignition repair.
Faulty car key fob or remote
If the buttons are worn or the fob is unresponsive, we’ll diagnose whether you need key fob repair, a new battery, or a replacement fob programmed to your car. See more in key fob not working.
Need a spare car key
A spare saves hassle, reduces future costs, and increases resale value. We can duplicate and program spares at your location—often in one visit.

Security, Insurance, and Peace of Mind

Dealer vs Auto Locksmith: What’s Best for Car Key Replacement?

Main dealers provide excellent service but often require recovery of the vehicle, proof of ownership, and a wait for parts or coding slots. As a mobile auto locksmith, we can usually:

Come to your location the same day or at a time that suits you
Replace and program keys roadside with dealer-level diagnostics
Provide a cost-effective alternative to recovery and long waits
Offer spare keys and on-the-spot testing before you drive away

Yes. We supply and program smart keys, keyless entry fobs, and push-to-start keys for many brands. For certain models, additional immobiliser or ECU programming may be required.
