When You Need Car Key Programming
Car key programming is required any time your vehicle’s immobiliser needs to recognise a key or fob. Common scenarios include:
- You’ve purchased a replacement or spare key that needs coding to your car
- Your car displays “key not detected”, a key symbol on the dash, or fails to start
- The remote buttons lock/unlock, but the engine won’t crank (or vice versa)
- You’ve replaced a fob battery and the remote now needs re-syncing
- The immobiliser light flashes and the vehicle security system won’t authorise start
- After an ECU, BCM, steering lock, or ignition switch repair or replacement
- Water damage or physical damage has affected the transponder chip
- Your central locking works intermittently or not at all
- All keys have been lost and the immobiliser needs fresh keys programming
If your fob is intermittently unreliable or dead, our diagnostic process confirms whether the fault is with the key, its transponder, the vehicle antenna/receiver, or the immobiliser module itself. For symptom-led guidance, see our quick help page for a key fob not working.

How Our Car Key Programming Works
We bring dealer-level capability to your kerbside. Our mobile vans carry professional diagnostics, OBD2 interfaces, EEPROM programmers, and key cutting machines for laser and high-security blades.
- Confirm and assess
- We confirm your vehicle details (make, model, year) and proof of ownership.
- Quick triage of symptoms (e.g., “key not detected”, immobiliser light) guides our approach.
- Diagnostic read and PIN/security extraction
- Using OBD2 key programming tools, we read immobiliser data and security codes (e.g., PIN, incode/outcode) where permitted.
- For vehicles that don’t allow OBD coding or when all keys are lost, we can safely remove the relevant module (e.g., immobiliser, ECU, BCM) for bench programming via EEPROM.
- Key cutting and transponder preparation
- We cut your key on-site with dealer-accuracy using high-precision machines for standard and laser-cut blades.
- We prepare a compatible transponder chip and remote board for your vehicle’s system.
- Programming and pairing
- We programme keys/fobs to your immobiliser and pair remote central locking functions.
- Where needed, we synchronise comfort features (e.g., boot release, mirror fold) and reset learned keys if security demands it.
- Testing and handover
- We test start, immobiliser authorisation, remote range, lock/unlock on all doors, and boot/bonnet where applicable.
- You drive away with a fully working key—backed by our workmanship warranty.
Non-destructive first: Wherever possible, programming is completed via the diagnostic port and standard procedures, avoiding dismantling. In rare cases—such as water-damaged modules or locked immobilisers—EEPROM/bench work or part removal is required. We always explain your options and obtain approval before proceeding.
Advanced Immobiliser & EEPROM Services
Modern vehicles can lock down programming after failed attempts, low voltage events, or security updates. Our advanced services include:
- EEPROM key programming for all-keys-lost scenarios
- ECU/immobiliser programming and synchronisation
- Security PIN code retrieval and token-based procedures for applicable platforms
- Remote central locking repair and re-synchronisation
- Steering lock and ignition switch coding after replacement
- Key cloning where appropriate and secure to do so
- Anti-theft and car security assessments if keys were lost or stolen
We use dealer-level diagnostic methods and specialist tools to work safely with your vehicle electronics. Where soldering or conformal coating removal is required for bench work, we follow ESD-safe procedures and reinstate components to manufacturer standards.

FAQs
Can a locksmith programme a car key without the original?
Yes—on most vehicles we can programme a new key from scratch without the original. We use OBD2 key programming to read immobiliser data, or EEPROM/bench programming when the vehicle security system does not permit standard coding. Proof of ownership is required for all all-keys-lost jobs.
How long does car key programming take?
Many programming jobs can be completed in a single visit, often under an hour once on site. The exact time depends on your vehicle brand, immobiliser system, whether a key needs cutting, and whether advanced EEPROM/bench work is required. We give a realistic timescale after initial diagnostics.
How much does car key programming cost in Kingston upon Thames?
Costs vary by make, model, year, key type (basic/transponder/smart), and whether you have a working key. Emergency timing, travel, and any ECU/immobiliser work also affect price. For transparent guidance tailored to your vehicle, please see our overview of auto locksmith prices in Kingston upon Thames and request a free quote.
Can you programme a used key fob?
Sometimes. Certain brands allow reprogramming a used fob; others lock fobs to the first vehicle permanently. Even when possible, a used fob may need a new blade and a compatible transponder. We’ll advise whether a used fob is viable or if a new unit is the safer, more reliable option.
Will programming damage my car or void my warranty?
No. We use non-destructive diagnostic methods wherever possible and follow manufacturer-safe procedures. When a module must be removed for EEPROM work, we protect components and reconnect to spec. We explain any risks in advance and warranty our workmanship.
My car shows a key symbol on the dash and won’t start—what should I do?
That symbol usually indicates an immobiliser communication issue. Avoid repeated attempts that could lock the system. Call us for diagnostics; we’ll check the transponder chip, key antenna, immobiliser status, and wiring, and then programme or repair as needed to restore authorisation.
Do you cover evenings and weekends?
Yes, we offer flexible mobile appointments and can support urgent needs. For out-of-hours lockouts or critical issues, our emergency team can help—start at our Emergency Auto Locksmith in Kingston upon Thames.
