When You Need Car Key Programming
Modern vehicles use immobiliser systems that require the key to be electronically matched to the car. You may need car key programming if:
- You’ve lost your only key and need a replacement programmed from scratch
- Your spare or new key needs transponder programming to start the engine
- The remote locking/unlocking has stopped working and needs re-syncing
- You’ve replaced a key fob shell or battery and it no longer responds
- The dashboard shows a key symbol or immobiliser warning
- The car says “Key Not Detected” with push-to-start systems
- You’ve had ECU or immobiliser work and need keys adapting
- A used key or fob needs evaluating and, where possible, reprogramming
Common issues we resolve every day:
- Car key not working / stopped working
- Key fob not responding; central locking not operating
- Car won’t start; key symbol on dash; immobiliser light flashing
- Faulty remote after battery change; need key fob programming service
- Keyless entry and proximity key replacement and programming
If you’re locked out right now or keys are missing, our vehicle unlocking service and lost or stolen car keys help can be combined with immediate programming on-site.
How Our Car Key Programming Works
We use non-destructive, manufacturer-aligned methods wherever possible, backed by dealer-level equipment and years of hands-on experience with UK and European models.
-
Identify Your Vehicle and Key Type
We confirm the vehicle make, model, year, and key type (transponder, remote fob, smart/proximity). This ensures we bring the correct blanks, chips, and diagnostic tools. -
On-Site Diagnostics and Security Access
Our mobile units are equipped with OBD2 diagnostics and specialist software to access your vehicle’s immobiliser system safely and legally. Where standard methods are insufficient (some older or higher-security systems), we can perform EEPROM key programming or ECU/immobiliser programming to code keys at the chip level. -
Programming and Synchronisation
- Transponder key programming: pairs the chip in your key with the immobiliser so the engine starts.
- Remote key programming: syncs locking, boot release, and panic functions.
- Smart key programming: adapts proximity/push-to-start keys and re-syncs keyless entry.
- Remote central locking repair: we test and, if needed, repair or replace the fob’s components (switches, batteries, cases) and reprogram.
-
Cutting and Testing
If you need a physical blade, we cut laser cut or standard keys precisely, then test all functions—starting, locking, remote range, and keyless start. We’ll also disable missing/stolen keys on request so they no longer operate the vehicle. -
Final Handover and Advice
We demonstrate your new key, provide usage tips, and recommend a spare for peace of mind. Our workmanship and keys are covered by warranty, and we’re always available for aftercare.
In rare cases (for example, heavily damaged locks or a tampered ECU), we’ll explain any exceptions and, if required, discuss safe repair or replacement options before work begins.

FAQs
Can a locksmith make and program a car key without the original?
Yes. In most cases we can create and program a new key without the original using security-authorised OBD2 access, immobiliser data, or EEPROM programming. We also verify proof of ownership before proceeding for your security.
How long does car key programming take?
Many standard keys can be cut and programmed within a single visit, often under an hour once on-site. Complex systems, lost-all-keys scenarios, or EEPROM-level work may take longer. We’ll give a realistic timeframe when you contact us.
Can you reprogram a used key fob?
Sometimes. Certain vehicles allow reprogramming of used remotes, but many modern systems lock keys to an original car. We’ll assess your specific make/model and advise whether a new, virgin key is required.
My car says “Key Not Detected.” What should I do?
First, try a fresh battery in the fob and hold it close to the start button or steering column (some cars have a hidden backup antenna). If that fails, the key may need re-syncing or replacement. We’ll test, repair, or reprogram as needed.
Will programming damage my car?
No. We use non-destructive, manufacturer-aligned diagnostics. In rare cases where components are faulty or tampered with, we will explain your options before any additional work.
Do you cover evenings and weekends?
Yes. We offer emergency support. If you’re stuck now, please see our Emergency Auto Locksmith in Redhill and call us for immediate assistance.
What You’ll Need When We Arrive
- Proof of ownership (e.g., V5C logbook or insurance certificate)
- Photo ID
- The vehicle present (for programming and testing)
- Any remaining keys or fobs (so we can test, disable lost keys, and synchronise everything)
Bringing these helps us complete programming efficiently so you’re back on the road sooner.
