Key Not Recognized - Vehicle Won't Start

I have a 2019 X7. The key fob will lock and unlock the car by pressing the buttons but comfort access does not work. The key is also not recognized when I try to start the vehicle. I've tried both keys with the same result. When I hold the key to the steering column it doesn't pair. Does anyone have any other ideas?

One of my 2 keys did the same thing. I changed the battery and it was working fine. Battery is CR2032.

Thanks for the suggestion. I don't think that's it. I have a display key and charged it fully and the vehicle won't start with that. The vehicle also won't start when I try to precondition using the display key or the app. The car also won't start when I try using the NFC keycard.

How did you get a display key?

@Paultattoo, Jthompson's is a 2019 X7 so the display key was available. Discontinued for 2020.
Regarding mine, it was the regular keys that came with the car.

You need to go into the car/settings menu and allow for preconditioning. It's in a weird place but it's something you need to turn on in I drive. Climate control- preconditioning/ ventilation remote engine start

Yes, remote Start must be enabled/allowed from your car via iDrive. Next you can start the car by pressing lock button 3 times using regular FOB, or you can use your Display Key to start or you can use your BMW Connected Apps... Here is where the setting is located, there may be minor difference depending on software version..

If you don't use the vehicle for few days and approach it with the keyfob, comfort mode will not work. You must open the vehicle via the keyfob or door handle. After starting it the next time you enter it will work as you would expect.

Is this what you experienced?

I have the same problem in the last two weeks. Not only isnít the car recognizing me as I walk up to it, but when I try to start the car it says the key isnít in the car. I literally have to hold the fob up against the steering column in order for it to recognize it.

Yes, I changed my battery last week, itís not the battery.

I've already done that. I've preconditioned before where the vehicle starts. It won't work now.

No. The vehicle won't start at all. I used the unlock button on the remote to get in. The vehicle won't start. I've held it up to the steering column and it's not being recognized.

I couldn't take it back to the dealership. The vehicle wouldn't start.

I had it towed to my local dealership. The control module for comfort access and the ignition was bad. They replaced that and when they tried to get it all up and running the head unit crashed. They tried to reprogram the head unit both from the dealership and also remotely from a BMW tech and neither could get the head unit reprogrammed.

A new head unit module was ordered and should be here tomorrow. Here's to hoping this fixes the issue and there are no further problems.

Is there a physical key to start the car up manually in situations like this?

Not to my knowledge. If there is one, I'd sure like to know. I will ask my SA when I pick up my vehicle.

I've had this happen a few times. When I'm in the car, with the key it acts like I don't have it. I've found that if I place it in the charging dock near the cupholders, it'll then see it and it works fine.

Seems like dealers create even more problems when cars are brought in for service.
