E90 poor key fob range

dleccord · 01-02-2021, 03:54 PM

Happy 2021. Probably the most annoying thing for our E90s besides BMW decision to have a base sound system would be the crappy range on our key fobs. Has anyone been able to figure out if we can install a longer range antenna or replace a stronger key fob? I’m tired of putting it next to my head to lock my car...

Things that can cause low range.
1)Low keyfob battery or Car Battery .
2)Tint.
3)Corrosion at the antenna connections or wiring.
4)Diversity Module (Antenna Module) going bad.
