When You Need Car Key Replacement

Car key problems are stressful and often urgent. Here are common scenarios where our mobile car locksmith service can help anywhere in South West London:

Lost car keys: Misplaced at home, the gym, or out in Clapham, Battersea, or Wimbledon.
Stolen car keys: We can erase lost/stolen keys from your vehicle’s immobiliser and supply/programme new ones.
Broken car key: Snapped blade, cracked flip key, or damaged remote housing needing replacement.
Key not working: Faulty buttons, worn transponder chip, or key fob not responding.
Need a spare key: Avoid future lockouts and reduce costs by adding a spare while you still have a working key.
Central locking or ignition issues: If the key won’t turn, or the dash shows a key symbol, you may need a new key paired to your immobiliser.
Aftermarket upgrades: Replace worn keys with a robust flip key or upgrade for convenience.

If your key has stopped working suddenly, or the car shows “Key Not Detected,” we can diagnose if the fault is with the key, the battery, the ignition barrel, or the immobiliser system. Our technicians carry advanced diagnostics to pinpoint the issue, saving you time and money.

For immediate lockouts, see our dedicated Vehicle Unlocking page, or if you believe your keys were taken, read about lost or stolen car keys for safety steps and immobiliser reprogramming.

Our Car Key Replacement Service, Step by Step

We’ve designed a clear and efficient process to take the stress out of getting new car keys made in South West London.

Quick Assessment and Quote

Call us or send details via our contact form.
Share your vehicle make, model, year, location (e.g., SW11, SW19, SW1V), and whether you have a working key.
We explain your options (replacement, repair, spare key) and give a free, no-obligation quote with no hidden fees.

Mobile Dispatch to Your Location

A fully equipped mobile auto locksmith comes to you—home, work, roadside, or car park—from Balham and Battersea to Putney, Richmond Park, and Brixton.
We never promise exact arrival times, but we prioritise urgent jobs and dispatch efficiently across SW postcodes.

Non-Destructive Entry Where Needed

Locked out? We use specialist tools and non-destructive techniques to unlock your vehicle wherever possible.
On rare occasions when drilling or component removal is necessary (e.g., severely damaged locks), we explain the reasons and get your consent first.

Key Cutting and Transponder Programming On-Site

We cut your new key using precision equipment, including laser cutting for high-security blades.
We programme the transponder chip and remote functions using dealer-level diagnostics via OBD2. For certain models, EEPROM or ECU/immobiliser programming may be required—our technicians are trained and equipped for this.
We can also erase lost/stolen keys from the vehicle’s memory for security.

Testing and Handover

We test the key in the locks and ignition, check remote locking/unlocking, and confirm the immobiliser handshake.
You’ll receive guidance on battery care and usage, and we provide a warranty on our workmanship and keys.

Types of Car Keys We Replace and Programme

We supply, cut, and programme most key types across modern and older vehicles:

Standard blade keys: Traditional keys for older models; quick cutting and basic transponder pairing where applicable.
Remote keys and flip keys: Folding blades with lock/unlock buttons; case repairs or full replacement available.
Smart keys/proximity keys: Push-to-start systems for brands like BMW, Mercedes-Benz, Audi, VW, Toyota, Nissan, Kia, Hyundai, and more.
High-security and laser-cut keys: For vehicles with milled edges and advanced anti-theft profiles.
Van and commercial keys: Including Ford Transit, Vauxhall Vivaro, Mercedes Sprinter, VW Transporter—ideal for sole traders and fleet managers.

If you’re unsure what key you have, a quick photo or description over the phone will help us identify the right solution.

Advanced Tools and Techniques We Use

We invest in the same level of tooling you’d expect at a main dealer, delivered to your kerbside:

OBD2 diagnostics: Dealer-level programming to pair transponder chips and remotes securely to your vehicle.
EEPROM/ECU/immobiliser programming: For models where OBD2 programming alone is insufficient or keys must be generated from module data.
High-precision cutting: For laser-cut and high-security vehicle keys.
Remote testing and repair: Signal testing for key fobs, plus switch and casing repairs where practical.
Door and ignition lock decoding: Non-destructive methods to obtain key profiles when no key is available.

This capability means we can often provide same-day or next-day solutions without the delays and costs of dealer ordering.

Lost, Stolen, or Broken: Tailored Solutions for Every Situation

Lost car keys: We can create a new key from scratch without the original. We’ll pair it to your immobiliser and, if needed, erase missing keys so they can’t start the car. For guidance on next steps, visit lost or stolen car keys.
Stolen keys: For your security, we recommend immobiliser reprogramming to de-authorise stolen keys. We can also rekey locks or change ignition barrels if required.
Broken or snapped keys: Whether the blade has broken in the lock or the flip hinge has failed, we can extract, repair, or replace as needed. Find more detail at broken car key.
Key fob not working: Button failure, worn contacts, or water damage can all stop a fob from responding. We diagnose and provide repair or replacement. See key fob not working.
Ignition and lock issues: If the key won’t turn, or the ignition sticks, the issue may be with the barrel or the key. We offer car lock and ignition issue repairs alongside replacement keys.

Spare Car Keys: Save Money and Avoid Stress

Replacing a key when you have no working key can be more complex and time-consuming because the vehicle often needs special programming steps. Adding a spare while you still have a working key is usually quicker and cheaper. We can supply a basic non-remote spare or a full remote/smart key—whichever suits your needs and budget. Many customers in Wimbledon, Putney, and Battersea choose to add a spare during a service visit to avoid future disruption.

Cost-effectiveness: With on-vehicle programming and cutting, you avoid additional dealership surcharges and transport costs.
