Car Key Cutting & Duplication in Bromley

If you need fast, precise Car Key Cutting & Duplication in Bromley, you’re in the right place. Our mobile auto locksmith team provides accurate key cutting and spare key duplication for all major makes and models across Bromley and the wider BR postcode area. Whether you’ve only got one key left, your blade is worn, or you want extra keys for family or fleet drivers, we cut and program replacements on the spot using dealer-level equipment—saving you time and hassle.

When You Need Car Key Cutting And A Spare Key

There are plenty of everyday reasons drivers call us for car key cutting and duplication in Bromley:

You only have one working car key and want a spare for peace of mind
Your current key blade is worn, bent, or unreliable in the locks or ignition
You’ve changed a worn lock or ignition barrel and need a freshly cut blade
You share the car and want separate keys for convenience
Your fleet or van requires additional keys for new drivers
Your flip key’s blade pin has failed and the blade needs replacing
Your remote still works, but the blade won’t turn the lock smoothly

A spare key is far cheaper and quicker than dealing with lost or stolen keys later on. We can create standard metal blades, laser-cut/high-security keys, flip keys, and smart key backups with fully working transponders and remote functions.

If your issue is more than a spare—such as total key loss or a non-starting vehicle—see our Car Key Replacement service for creating new keys from scratch and programming them to your immobiliser.

We handle virtually all modern and classic key types used in the UK market:

How Our Car Key Cutting & Duplication Service Works

We bring the workshop to you. Our fully equipped mobile units cover Bromley and all BR postcodes, from Beckenham, West Wickham, and Shortlands to Orpington, Petts Wood, and Biggin Hill.

Quick assessment and quote

We confirm your vehicle make, model, year, and existing key type.
We provide a free, no-obligation quote with clear options for blade-only, remote, or full smart key duplication.

Precise key cutting

We use computer-controlled key cutting machines to clone your key’s exact profile.
For laser-cut and high-security blades, we use calibrated cutters to match the original pattern and depth.

Transponder and remote programming (if required)

Most modern vehicles require programming. We connect dealer-level diagnostics via the OBD2 port to program the transponder chip and sync remote buttons.
For certain immobiliser systems and late-model smart keys, we use advanced methods such as EEPROM/ECU programming where appropriate to ensure the new key starts the car reliably.

Testing and validation

We test the key mechanically in the door/boot and ignition.
We verify the vehicle starts, the immobiliser accepts the chip, and the remote locks/unlocks and, where applicable, handles keyless entry and push-to-start.

Handover and guidance

You’ll receive your new spare key and simple advice on storage and maintenance, including battery care for remotes.

A note on non-destructive methods: For cutting and duplicating from a working key, our process is entirely non-destructive. In rare cases where you need a blade cut without an original or where locks are heavily worn, we may need to decode the lock or adjust the wafer pack. Any exceptions and risks are explained clearly before we proceed.

Car Key Cutting Or Full Key Replacement—What’s The Difference?

Cutting and duplication:
Best when you still have a working key or an original blade to copy. We produce a spare and, if needed, program the transponder and remote.
Full replacement:
Needed when you’ve lost all keys or the only key is too damaged to read. This involves decoding the lock, sourcing the correct key profile, cutting from code, and programming the immobiliser from scratch. Learn more at Car Key Replacement.

If your remote or smart key has stopped responding, you may need programming support. Visit our Car Key Programming page, or if buttons fail or the key isn’t detected, see Key Fob Not Working.

Our Tools And Technical edge

Computer-controlled key cutting machines for standard and laser-cut blades
OEM-spec and aftermarket key blanks to match manufacturer standards
OBD2 diagnostic tools for immobiliser and remote pairing
EEPROM and immobiliser programming capabilities for certain models and lost-key scenarios
Key code reading, lock decoding, and precise depth calibration
Battery testing and replacement for remote keys
Blade pin replacement for flip keys and key blade repairs

In simple terms: a transponder is a small chip inside your key that “talks” to your car’s immobiliser. Even a perfectly cut blade won’t start many modern cars unless the transponder is paired. We handle both the cut and the code, so your spare works flawlessly.

Common Questions About Car Key Cutting And Duplication

Can you duplicate my key if I only have one?

Yes. If you have a single working key, we can cut and program a spare so you’re not left stranded if the original is lost or damaged. It’s more affordable than replacing all keys later.

Can you cut laser-cut and high-security keys?

Absolutely. We use calibrated, computer-controlled cutters for high-security and laser-cut blades, commonly found on newer vehicles and premium brands.

Do you program the transponder and remote as well?

Yes. Most modern cars need transponder programming and often remote-button syncing too. We provide complete duplication, including car key programming where required.

Will the spare key start my car and work the central locking?

We test before handover. Your spare key will be cut to turn locks smoothly and, if specified, programmed to start the engine and operate the remote locking. For smart keys, we verify keyless entry and push-to-start.

What if my current key is worn or intermittently failing?

We can cut a new blade to original specifications and, if needed, replace the key shell, buttons, or battery. If the electronic chip is failing, we’ll program a new transponder or remote.

Can you create a spare key without the original?

In many cases, yes. If the original is missing, this moves into replacement work—decoding the lock and programming a new key from code rather than simple duplication. See car key replacement Bromley.

How long does it take to cut and duplicate a key?

Often under an hour for standard keys. High-security, remote, and smart keys can take longer due to programming and verification, but we complete everything on-site wherever possible.

Will you damage my vehicle?

No. Key cutting and duplication are non-destructive. In rare cases where locks or ignitions are excessively worn, we’ll discuss options and any minor adjustments before work begins.
