BMW key specialist support
Modern BMW keys are part of a wider security system.
A replacement BMW key must be cut, programmed and tested as a complete access-and-authorisation device.
Depending on the model and year, the vehicle may use an older remote key, CAS-based system, FEM or BDC architecture, Comfort Access proximity functions or newer digital-key features.
Odell Automotive provides mobile support for compatible BMW vehicles and explains clearly what can be completed at the vehicle, what information is required and what limitations apply.

BMW key security
Lost keys need more than a replacement.
Where supported, a missing BMW key can be removed from the vehicle's authorised key list. This may prevent it from starting the vehicle, but it does not necessarily change the physical lock or disable every connected function.
Read the vehicle security guide →Replace access
Create a working replacement so the vehicle remains usable.
Review authorisation
Check whether the missing key can be deleted from vehicle memory.
Consider mechanical access
A previously cut blade may still operate the physical lock.
Review key storage
Use sensible storage and signal-blocking precautions where relevant.

BMW locksmith FAQs
BMW key questions, clearly answered.
Exact capability depends on the vehicle's production date, key system and condition.
Can you make a BMW key when every key is lost?
Support is available for many compatible BMW vehicles. The registration, year, model and exact situation must be checked first.
Can you programme BMW Comfort Access keys?
Some Comfort Access systems are supported. Compatibility depends on the vehicle, key type and available programming procedure.
Can a lost BMW key be disabled?
On supported systems, the missing key may be removed from the authorised key list so it no longer starts the vehicle.
Will deleting the key stop the blade opening the door?
Not necessarily. Electronic deletion does not alter the mechanical lock.
Do you come to the vehicle?
Yes. Odell Automotive provides mobile service at suitable homes, workplaces, garages, depots and roadside locations.
Can you make a spare BMW key?
Yes, for many supported BMW vehicles when a working key is still available.
Why does my BMW say key not detected?
Possible causes include key battery condition, key damage, vehicle battery condition, antenna faults or an authorisation issue. Proper diagnosis may be required.
Can you repair a damaged BMW key?
Depending on the damage, the key may need a new shell, blade, buttons or complete replacement.
Can you open a BMW with the keys locked inside?
Professional entry is available for suitable vehicles after ownership and authority are verified.
Do you support older BMW models?
Many older vehicles are supported, but the exact system and required parts must be confirmed.
Do you support BMW electric models?
Some BMW i models are supported for conventional key-related work. Connected-app and digital-key functions may remain manufacturer-controlled.
Is a mobile locksmith always cheaper than a BMW dealer?
Not always. Cost depends on the exact vehicle, key type, parts, programming procedure and whether recovery would otherwise be needed.
How long does BMW key programming take?
Timing varies significantly by system, vehicle condition, key availability and required security procedure.
What details do you need before quoting?
Registration, model, year, location, number of working keys and a clear description of the fault or loss.
