When 3 Series owners call us
A useful example is an all-keys-lost car that needs vehicle-side authorisation. That kind of symptom shapes what we test first.
The only key has gone
No working key? On supported 3 Series versions, the blade is cut from the lock and a new key added to the immobiliser.
3 Series will not accept the key
A 3 Series that unlocks but will not start points away from the remote and towards the transponder or immobiliser, which is where testing begins.
Only one key
One 3 Series key is a risk. A spare made now avoids a bigger job later.
Why the 3 Series model year matters
How a 3 Series key is coded depends on its generation and equipment level.Remote keys across earlier generations and later comfort-access smart keys. Coding tells the immobiliser to accept the new key. Remote locking and keyless entry are checked as separate steps, along with the emergency blade. Very new cars sometimes carry restrictions; we tell you upfront if yours does.

The right key for this 3 Series
The BMW 3 Series is a saloon and Touring range. The useful model-specific point is generation changes across a long-running model line.
A 3 Series key has to match in three ways: the blade, the electronics and the car's own security records. Generations range from remote keys across earlier generations and later comfort-access smart keys.
