Which 3 Series Generation Are You Driving?
The 3 Series has used several distinct key types. E46 cars, built roughly between 1998 and 2006, use a bladed remote, while E90, E91, E92 and E93 models from around 2005–2013 use a slot key. Giving us the registration helps establish which generation your enquiry concerns.
F30/F31 models cover approximately 2012–2019, with the G20 arriving around 2019. These later cars use remote or comfort access keys. Some E9x cars may have electronic steering lock faults, so describe what happens when you try the key rather than assuming that replacement is the answer. Our main BMW page explains coverage beyond the 3 Series.
3 Series Spare Key Options
A 3 Series spare key gives you another key before a loss becomes urgent. Tell us what you already have, including whether it is a bladed remote, slot key or comfort access version. We can then discuss the appropriate spare key service for your car.
Matching the generation
E46 models use EWS, and E9x cars use CAS. Later F30 models use FEM or BDC, while the G20 uses BDC. We carry out 3 Series key programming at the vehicle across these systems, rather than asking you to bring the car to a workshop.
Comfort access enquiries
Comfort access keys are paired for keyless entry. Mention this feature when requesting a 3 Series spare key so the enquiry reflects your existing setup. Put your V5C ownership document and photo ID aside for the appointment, as making a key depends on us checking both first.
BMW 3 Series keys, sorted at the vehicle anywhere in the New Forest.
When There Is No Key Left To Use
A lost 3 Series key can be dealt with at home, outside work, in a car park or at the roadside. Our all-keys-lost service includes FEM and BDC cars, so later generations are not automatically dealer-only. Both replacement and 3 Series key programming are handled at your BMW.
You will know the quoted price before we travel, and no payment is required upfront. If what we find changes the job, work waits while we explain the new cost; choosing not to accept it leaves you with no call-out charge. Across the New Forest, 45–60 minutes is our usual arrival window, with daily working hours of 8am–11pm.
Tell us your registration, location and whether any key remains when you contact us. We will discuss the next step for your 3 Series and provide a price before arranging the visit.
