Car Key Programming, Replacement Keys & Immobiliser Help
Whether you have one working key, have lost every key or are dealing with a key-not-recognised warning, the right first step is to identify the vehicle and its security system. We assess supported car and van keys, transponder programming, remote or smart-key learning and immobiliser faults. Some vehicles require further diagnostics, approved security access or workshop work before a key can be programmed.

Lost car keys and replacement options
Lost All Car Keys? Replacement & Spare Key Options
If you have lost all your car keys, the available procedure depends on the vehicle year, immobiliser platform, access permissions and whether a suitable replacement key can be supplied. For drivers with a working key, adding a compatible spare can be more straightforward. We assess whether key learning, remote pairing or further diagnosis is appropriate before confirming a booking.
Security-related work requires proof of identity, vehicle ownership and permission to proceed. If the fault involves an ECU or immobiliser module rather than the key itself, see our specialist immobiliser diagnostics and programming service.
Vehicle key programming services
Spare Car Keys, Remote Fobs & Lost-Key Support
Not every key problem requires the same repair. Vehicle keys may contain a mechanical blade, immobiliser transponder, remote-control electronics or proximity technology. We identify the correct key type and programming route before discussing availability or cost.
All keys lost
No working key available? We assess the vehicle’s all-keys-lost procedure and required documents before confirming support.
Remote key fob programming
Remote locking stopped working or a replacement fob needs pairing? The remote and immobiliser functions may require different checks.
Transponder key programming
A cut key may turn in the lock but still not start the engine. A compatible transponder may need authorised learning to the vehicle.
Smart and keyless car keys
Selected proximity keys and push-button start systems require vehicle-specific security access and matching key hardware.
Van and motorhome keys
Key programming assessments for supported commercial vans, pickups and motorhomes, based on the vehicle’s underlying security system.
When the car does not recognise the key
Car Key Not Recognised? Immobiliser Fault Diagnostics
A flashing immobiliser light or non-start fault does not always mean you need a new key. Low battery voltage, key readers, antennas, wiring, body control modules and ECU communication can cause similar symptoms. SGTM checks the evidence before recommending programming, coding or a replacement part.
Key not recognised
Assess key identification and transponder communication when the vehicle displays a key-not-detected message or refuses to start.
Immobiliser warning light
Investigate security-system warnings and relevant diagnostic trouble codes before attempting programming.
ECU & immobiliser synchronisation
Where supported, diagnose start-authorisation faults following compatible ECU or immobiliser module replacement.
Security module coding
Some BCM, BSI or related modules require specialist coding or adaptation; availability is confirmed per vehicle.

By-appointment mobile service
Mobile Car Key Programming Birmingham & West Midlands
Mobile appointments may be available in Birmingham, including Edgbaston, Harborne, Selly Oak, Sutton Coldfield and surrounding districts, and elsewhere across the West Midlands. We also assess enquiries from Dudley, Halesowen, Stourbridge, Wolverhampton, Walsall, West Bromwich and Solihull.
SG-Tronic Motorsport operates from the Stourbridge area; we do not represent the workshop as a Birmingham city-centre branch. Attendance is by prior arrangement and depends on postcode, vehicle access, safety, key availability and the programming method required.
Diagnostic-led vehicle security work
Why Choose SG-Tronic Motorsport for Car Key Programming?
We approach vehicle security work as an automotive electronics problem, not simply a replacement-key sale. That means checking the symptoms, vehicle identity and programming requirements first, explaining what can be done and providing an individual quotation before attendance.
Vehicle-specific assessment
We check the make, model, key situation and immobiliser technology rather than promising a universal solution.
Convenient mobile appointments
Where the procedure is suitable, work may be arranged at your home, workplace or accessible vehicle location.
Diagnosis before replacement
We investigate key readers, supply voltage, communication and related faults if key programming alone may not help.
Clear security & ownership checks
Proof of authority is requested before security-related work, with the service scope explained in advance.
How Our Mobile Key Programming Service Works
Tell us about the car
Send the registration or make/model/year, postcode, and whether you have a working key. Describe any dashboard warning.
We check key compatibility
We review the vehicle security system, key requirements and whether mobile attendance or additional checks are suitable.
Receive an individual quotation
We explain the proposed service, required identification, parts dependencies and any diagnostic or travel costs before booking.
Programming & final checks
For authorised, supported work, key operation and relevant remote or start-authorisation functions are checked as applicable.
A non-start is not always a key failure
Why Your Car May Say “Key Not Detected”
A damaged transponder, depleted remote battery, key reader fault, vehicle battery problem or lost immobiliser synchronisation may all present as a key fault. Symptoms such as “Key not detected”, a flashing immobiliser light or intermittent starting need a vehicle-specific assessment.
If your vehicle will not start, describe exactly what happens when you turn the key or press Start, including dashboard messages and any spare-key behaviour. For wider electrical or communication faults, see mobile vehicle diagnostics in Birmingham or our immobiliser service.
Understand your quotation
How Much Does Mobile Car Key Programming Cost?
The correct price depends on the vehicle, number of working keys, replacement key specification and programming procedure. We do not advertise a one-price-fits-all quote or guarantee that every enquiry can be completed on site. Provide the details below so we can assess what is involved.
Vehicle make & security system
The model year, immobiliser generation and required security permissions affect programming time and equipment.
Spare key or all keys lost
Adding a spare with a working key can differ significantly from an all-keys-lost procedure.
Key and remote type
A basic transponder key, remote fob and proximity smart key can require different parts and coding.
Mobile attendance & diagnosis
Postcode, access, travel and whether electrical or immobiliser fault finding is required affect the final quote.

Before you book
Car Key Programming Birmingham — FAQs
Can you program a spare car key if I have one working key?
For supported vehicles, adding a compatible spare key may be possible. We need the vehicle details, the existing key type and confirmation of security-system support before quoting.
Can you help if I have lost all my car keys?
All-keys-lost assessments are available for supported vehicles. Service depends on vehicle security access, suitable key availability, proof of ownership and whether mobile work is technically possible.
Do you offer mobile car key programming in Birmingham?
Mobile appointments may be arranged in Birmingham and nearby West Midlands areas. Availability depends on postcode, vehicle model, safe access and the required procedure; advance booking is necessary.
What if the car says “key not detected” or will not start?
This may involve the key, key reader, battery supply, immobiliser or another vehicle electronics fault. Diagnosis may be required before attempting key programming or replacing components.
Do you program remote fobs, transponders and smart keys?
We assess remote fob, transponder and smart-key programming for compatible vehicles. Some models require specific replacement keys, manufacturer security access or additional workshop work.
What information should I provide for a quote?
Send the make, model, year or registration, postcode, whether any key currently starts the car, and a brief description of the issue. Include a picture of the existing key when available.
How much is car key programming?
Cost varies by vehicle, whether you have a working key, the type of replacement key and any diagnostic or mobile attendance requirements. Contact us for an individual quotation.
Do I need proof of ownership?
Yes. Identification, vehicle ownership and authorisation checks are required before key or immobiliser security work can begin.
Can a used car key be programmed to another vehicle?
Not every used remote, transponder or smart key can be reused. The key technology, vehicle security system and proof of ownership must be checked first.

Specialist immobiliser & ECU support
Need Specialist Immobiliser or ECU Programming?
If the key is working but the vehicle still refuses to start, the issue may involve the immobiliser, ECU synchronisation, body module or communication network. Our specialist immobiliser service can assess compatible security-module and ECU programming work following an appropriate diagnosis.
