Professional Car Key Programming in Bromley
If you need professional car key programming in Bromley, our mobile auto locksmith team can help you quickly and safely. Whether your transponder chip needs pairing, your smart key won’t start the car, or your remote fob has lost synchronisation, we provide dealer-level key programming across Bromley and the wider BR postcode area. We come to you, diagnose the issue, and program new or replacement keys on the spot—so you avoid the cost and downtime of a main dealer visit.
When You Need Car Key Programming
Car key programming is required whenever the electronic security between your key and your vehicle needs updating, repairing, or re-matching. Common scenarios include:
- Lost car keys and no spare: We can program a new key or smart fob to your vehicle and, if necessary, securely erase missing keys.
- New spare key: We’ll cut and program a second key or fob so you’re never stranded again.
- Key fob not working: Buttons stop responding, central locking fails intermittently, or the car doesn’t detect your key.
- Immobiliser issues: The engine cranks but won’t start, or you see a key/immobiliser symbol on the dashboard.
- Battery change or ECU work: After a fob battery replacement, flat vehicle battery, or electrical work, your key may need re-synchronising.
- Key won’t start push-to-start vehicles: Proximity/smart keys sometimes need reprogramming so the car recognises them again.
- Worn or damaged keys: If we replace a damaged transponder or flip key, it must be programmed to match your immobiliser.
Typical symptoms we solve:
- Car says “key not detected”
- Key fob buttons don’t lock/unlock
- Red key symbol or immobiliser light on the dash
- Car won’t start even though the key turns
- Remote works but engine won’t run
- Central locking works on the blade but not on the fob
If any of this sounds familiar, our Bromley auto locksmiths can help. You can also explore likely causes on our page for key fob not working.
How Our Car Key Programming Service Works
We provide a fully mobile, end-to-end service across Bromley and all BR postcodes—ideal if you’re at home, at work, or roadside. Our process is designed to be quick, transparent, and secure.
- Secure identification and diagnostics
- We confirm you’re the keeper or have authorised access to the vehicle.
- We run dealer-level diagnostics via the OBD2 port to read immobiliser data, trouble codes, and key status.
- On certain makes or lost-all-keys situations, we may perform EEPROM work or ECU/immobiliser programming to retrieve or write secure data.
- Key cutting (if required)
- We cut a new blade using laser-cutting machinery or standard cutters, as needed, and decode the lock where necessary.
- High-security, sidewinder, and laser-cut car keys are supported.
- Programming and pairing
- Transponder key programming: We code the chip so your immobiliser accepts the key.
- Smart key programming: We pair proximity keys and push-to-start fobs so your vehicle recognises them.
- Remote key programming: We sync the locking/unlocking buttons and boot release functions.
- ECU/immobiliser programming: For certain brands and lost-all-keys jobs, we reprogram or adapt the immobiliser to accept new keys, and remove missing keys from memory for security.
- Testing and handover
- We test all functions: start/stop, remote lock/unlock, boot, and proximity where applicable.
- We show you how to use the new key/fob and provide aftercare guidance.
Tools and techniques we use:
- Dealer-level diagnostic software and key programming tools
- OBD2 key programming and immobiliser diagnostics
- EEPROM key programming for complex cases

FAQs About Car Key Programming
Can you program a new car key without the original?
Yes. In most cases we can create and program a new key without the original by accessing the vehicle’s immobiliser data via OBD2 diagnostics or, for certain models, using EEPROM techniques. We’ll also remove the lost key from memory for security.
How long does car key programming take?
Most standard keys and fobs are completed in one visit, often within an hour. Complex models or lost-all-keys jobs can take longer, especially if EEPROM or immobiliser module programming is required. We’ll give you a realistic timescale on arrival.
Do I need to go to a dealer for key programming?
Usually no. Our dealer-level tools allow us to program keys roadside or at your home in Bromley. Mobile locksmiths are often faster and more convenient than booking with a main dealer.
My key fob isn’t working after a battery change—can you fix it?
Yes. Sometimes the remote loses synchronisation and needs reprogramming. We’ll test the fob, replace the battery if needed, and re-sync or reprogram it so locking and starting functions work again. See key fob not working for common causes.
Can you reprogram a used car key fob?
It depends on the make and model. Many fobs can’t be reprogrammed once locked to a different vehicle, while others can be reset. We’ll advise honestly after a quick check.
Will programming damage my car?
No. Programming is a software-based process. In rare cases, certain vehicles require controlled access to modules; if that’s needed, we’ll explain the process and get your approval first.
Do you cover vans and commercial vehicles?
Yes. We program keys and fobs for popular vans such as Ford Transit/Custom, Mercedes Sprinter/Vito, Vauxhall Vivaro, VW Transporter, and more. You can also see our Van & Commercial Locksmith service.
What if my car still won’t start after programming?
We’ll run full diagnostics to identify other issues such as a faulty antenna ring, steering lock module, immobiliser fault, or ECU problem. If needed, we discuss next steps before any additional work.
