Car Key Replacement in Dartford

If you need fast, reliable car key replacement in Dartford, you’re in the right place. Our mobile auto locksmiths create, cut, and program new keys for all major makes and models across the DA postcode area—whether you’ve lost your only key, had your keys stolen, or just want a dependable spare. We use dealer-level diagnostics and non-destructive methods wherever possible to get you back on the road quickly and safely.

When You Need Car Key Replacement

Car key replacement becomes necessary in several common situations:

Lost car keys or stolen car keys
Your only key is locked in the car or boot and you need a new one cut and programmed
Broken or damaged key (cracked case, bent blade, key snapped)
Faulty car key fob or smart key not responding
Worn-out or intermittent transponder chip causing starting issues
Spare car keys needed for convenience or to share a vehicle
Central locking not working due to key fob failure

We handle traditional blade keys, remote fobs, flip keys, and modern smart/proximity keys for push-to-start vehicles. If your key fob stopped working suddenly, we can test and repair where appropriate or supply a new remote with full key fob programming service.

If your situation is urgent—locked out, stranded, or keys stolen—our emergency auto locksmith in Dartford can prioritise urgent vehicle entry and same-day key solutions wherever possible.

How Our Car Key Replacement Service Works

We’ve refined a clear, efficient process to replace your car keys quickly and correctly:

Quick Assessment and Security Check

We confirm vehicle details (make, model, year, fuel type) and your location across Dartford and the DA area.
For security, we verify proof of ownership and ID before any key cutting or programming.

Mobile Dispatch to Your Location

A fully equipped mobile technician arrives at your vehicle—home, work, roadside, train station, shopping centre car park—anywhere in Dartford, Crayford, Greenhithe, Bexleyheath, Erith, and surrounding DA postcodes.

Non-Destructive Vehicle Access (If Locked Out)

We use non-destructive entry techniques wherever possible to open the vehicle without damage. Only in rare cases with severe faults or deadlocks will we discuss alternative methods first and get your approval.

Key Cutting and Blade Matching

Your new key is precision-cut on site using laser cutting or high-security key machines to match the locks and ignition.

Transponder and Smart Key Programming

We connect dealer-level OBD2 diagnostics to synchronise your new key with the car’s immobiliser. For certain models (e.g., some VAG, BMW, Mercedes, Ford), EEPROM or ECU/immobiliser programming may be required—our specialists are trained and equipped for this advanced work.

Remote Functions and Testing

We program remote locking/unlocking, boot release, and smart entry where applicable, then test starting, central locking, and immobiliser authorisation before handover.

Optional Deactivation of Lost/Stolen Keys

For security, we can erase missing keys from your car’s memory so they can’t be used to start the vehicle in future.

We carry a wide range of genuine and high-quality aftermarket keys and remotes. Where manufacturer coding is required, we use dealer-level tools and secure data sources to ensure compatibility.

Car Key Types We Replace

Standard blade keys (older vehicles)
Remote fobs and flip keys
Transponder chip keys
Smart/proximity keys for push-to-start systems
High-security and laser cut keys
Van and commercial vehicle keys, including Ford Transit and Vauxhall Vivaro
Specialist keys for premium brands (BMW, Audi, Mercedes-Benz, Jaguar, Land Rover)

If your key is physically damaged but the electronics are sound, we can often transfer the internals to a new shell and replace the key blade—an affordable repair option. If your fob is unresponsive, we test batteries and circuitry and advise on key fob repair versus replacement.

Dealer-Level Equipment, Trained Technicians

Modern vehicles from 2014–2025 use sophisticated anti-theft systems. Our team invests in ongoing training and compliant tooling so we can:

Read PIN/ISN codes and pair new keys to immobilisers
Perform EEPROM programming on selected modules where needed
Handle keyless entry programming and proximity key replacement
Carry out secure data procedures on brands that require online coding
Diagnose central locking problems and key detection faults

This advanced capability helps us solve complex cases professionally—such as “key not detected” on push-to-start cars, or where previous keys have been lost and must be deleted for security.

Replacement vs Repair: Honest Advice

Not every key problem requires a full replacement. Where possible, we offer:

Key blade replacement or flip mechanism repair
Battery replacement and re-synchronisation
Key fob repair for buttons, shells, and worn contacts
Re-coding remote functions after a battery change

If repair is unreliable or not secure, we’ll recommend a replacement and explain the reasons clearly. Our goal is the most cost-effective, long-term solution for your car and your circumstances.

Security After Lost or Stolen Keys

If your keys are lost or stolen, we can:

Erase old keys from the vehicle memory to prevent starting
Recode locks if necessary
Provide new keys with full immobiliser pairing
Advise on simple steps to keep your vehicle safe

For stolen keys, consider informing your insurer and the police. We can supply basic documentation confirming keys have been deleted or replaced to support your claim.

For more on this scenario, see our guide to lost or stolen car keys.

Common Scenarios We Fix Daily

Lost only key for a VW Golf—new laser cut key and transponder programming on driveway
Ford Transit driver needs a spare for a fleet van—key cutting and remote programming at the depot
BMW smart key “not detected”—diagnosed and paired a new proximity key after module authorisation
Vauxhall Corsa flip key snapped—blade replacement and case refurb to save cost
Mercedes-Benz remote failed after battery change—tested, re-synchronised, then supplied new key when logic board fault found

If your key won’t turn or you have ignition issues, we also offer car lock and ignition repair.

FAQs

Can a locksmith make a car key without the original?

Yes. We can create a new key from your vehicle’s locks and program it to the immobiliser using diagnostics. Proof of ownership and ID are required for security. This is often faster and more convenient than waiting for a dealer.

How long does it take to get a new car key?

Many replacements are completed the same day, often during a single visit. Times vary by vehicle make/model, key type (basic, remote, smart), and whether advanced coding (EEPROM/online) is required.

Will you damage my car when making a new key?

No. We use non-destructive methods wherever possible and explain any rare exceptions in advance. For locked vehicles, our entry techniques are designed to avoid damage.

How do you program modern keys and fobs?

We use dealer-level OBD2 diagnostics to match your new key to the car’s immobiliser. Some vehicles require EEPROM or ECU/immobiliser programming—our technicians are trained for these advanced processes.

Can you disable my lost or stolen keys?

Yes. We can delete missing keys from your car’s memory so they can’t be used to start the engine. We can also replace locks if necessary.

Do you offer spare keys and key duplication near me?

Absolutely. We supply spare car keys across Dartford and the DA postcode area. It’s cheaper to duplicate a working key now than to replace a lost-only key later. For general services, visit our auto locksmith services in Dartford.
