Replace key battery a couple of weeks ago but every time I get into car get above message come up. No check control message in vehicle status. Key is working fine.
How do I get rid of message?
TIA

Just change the CR 2032 battery which is short on power and the message will go. It’s an easy thing to do.

Perhaps there was an issue with the replacement. I had the same message but it disappeared once I changed the battery

Changed battery today - one I replaced was new - and all now ok
Thanks Vossy 👍

Having a near 6 year old car, that recently needed the key battery replaced, my just over 1 year old car needed both key batteries replaced, the former a Ford, the later a BMW.

I’m thinking that the tailgate function on the fob, sooks a lot of juice from the battery, thoughts?

Why would the tailgate function suck more juice??

Edit - you mean because you have up hold it to close? Marginal, I’d say. More likely due to the massive variation in CR2032 cell quality.

Comfort access / proximity signal exchange is a battery killer. It's better now that keys "sleep", but a lot worse than press to open.

You would think that BMW would’ve ironed that out. I don’t have the comfort access (I assume that’s keyless entry) on my poverty spec car, so haE to use the buttons on the fob for just about every function
