If the key leaves the car’s interior, it will prompt that error message.

Another common cause is the key battery is low on power/reserve. I had that all the time with my G05 X5. The dealer service team was kind enough to replace the battery every time, and they remarked it’s very common on BMW’s latest models. At its most ridiculous, I was replacing the battery every couple weeks. Lessons learned:

1. Store your car keys at least 10-15 feet away from the vehicle, so they go to sleep after a time, vs. periodically communicating with each other. And never keep the key inside the vehicle, whereupon they communicate with each other constantly.

2. Skip the cheap replacement batteries the dealer offers, and get a reputable name brand battery instead. DuraCells have been lasting 10x longer for me vs. the cheap dealership batteries under the same conditions.
