BMW key types across the years
BMW has changed its key technology several times over the decades. Earlier BMWs often used simpler systems, but the brand moved to higher security as the years went on.
If you are not sure which key type you have, send a photo of your key along with your model and year and we will identify it.
- Older BMWs, especially earlier 3 Series and 5 Series, used basic transponder keys with a chip programmed to the immobiliser.
- Many mid-range BMWs use a remote key or flip key, where the remote and transponder are programmed as a pair.
- Newer BMWs, including recent X3, X5 and newer 5 Series models, use a smart or proximity key for keyless entry and push-button start.
- European keys vary a lot by model and year. Plenty are straightforward, but some of the newer high-security models are dealer-only, and we will tell you which before you book.
