🔑 This solution requires a key sacrifice
One of your working keys must be permanently mounted inside the vehicle, where it
satisfies the factory immobilizer during a remote start. That key is
given up for the life of the installation, so if you only have two keys,
budget for cutting a spare before you book.
It sounds worse than it is. The key sits hidden and untouched, your factory security is
unaffected, and on these vehicles it is the only method available.

This is the EUROSTART BRS3 remote starter, for the BMW 2 Series, 3 Series and 4 Series.
BMW is one of the hardest vehicles on the road to fit a remote starter to. The mainstream brands barely cover it, because BMW's CAS immobiliser and vehicle networks don't behave like anything else. EUROSTART is built specifically for that gap.
Starts from your factory key fob
Press lock three times on the fob you already carry and the car starts. Nothing extra on your keyring, no second remote, no aftermarket buttons in the cabin. For longer range than a factory fob manages, add smartphone control.
Your factory warranty is unaffected
The kit is designed to connect through your BMW's factory connectors rather than splicing into the harness, so the vehicle's wiring is left as BMW built it.
