One system, several possible causes
A vehicle may fail to recognise a key because of the key/transponder, immobiliser, BCM/BSI, ECU, steering lock, keyless module or related vehicle electronics. Programming a different key without checking the wider system may leave the original problem unresolved.
GEM reviews the vehicle, symptoms, key type and any previous module work. Relevant electronic checks help establish whether the next step is key cutting/programming, further diagnosis, supported module programming or another repair route.

Existing dealer-level diagnostic/programming capability, Launch X431 IMMO Plus and X-PROG equipment support assessment of suitable jobs. The exact vehicle generation, module condition, available parts and procedure determine what GEM can undertake.
A tool or stock key being available does not establish support for every model. GEM confirms the proposed work and any restrictions before arranging programming. Any vehicle-security requirements are discussed directly before work is agreed.
For a key enquiry, send the registration or make/model/year, postcode, symptoms, whether another key works, and any relevant replacement-module history. Key prices and diagnostic scope are confirmed for the individual vehicle.

Questions about your car key
Should I ask for programming or diagnosis?
If you have a working key and simply want a spare, start with the spare-key service. If the vehicle is not recognising a key or has a non-start fault, describe the symptoms so GEM can assess diagnosis first.
Can a fault involve both the key and a control module?
Yes. Key authorisation can depend on several modules and related electronics. The correct route depends on the vehicle system and fault.
Can all keys and modules be programmed?
No. Support is specific to the vehicle, key, module and procedure. Some work requires a different specialist or manufacturer route.
Is this a local mobile service?
Suitable key and diagnostic jobs are considered in Birmingham and surrounding West Midlands areas by arrangement. Contact GEM with the job and location first.
