No, you just have to follow a special procedure and the key is working again. This can happen after battery problems. I had the same problem on my X3. The only problem i ever had with this car. Best regards Joergen Planck Larsen

I was informed by a BMW dealer there isn't a battery to replace and you have to order a new remote and then have it programmed by the dealer.
yes
Cut open the remote with xacto knife , unsolder and replace the battery.
use a hammer..:)
To reinitialize a keyless remote battery on a BMW X5, first, replace the old battery with a new one, ensuring the positive side faces the correct direction. After replacing the battery, sit in the vehicle with the new key, close all doors, and press the start/stop button without pressing the brake pedal. This should reinitialize the key. If it doesn't work, you may need to consult the owner's manual or a BMW dealer for further assistance.
Test the battery with a tester.
BMW's have auto-locks a little different from other cars, if your battery is dead, the doors won't open. To change the battery, you need to open the trunk, this is where the battery is located. You will see a panel with some screws, you need to remove that and underneath is the battery.
small flat head screw driver pops off the back cover and there is a nickel size battery that needs to be replaced
battery is spent, now to get inside?be creative...
the battery is in the trunk under the trunk floor mat
No.
There is no battery inside the key to replace. The key actually charges through your ignition. If its not functioning you will just have to order a programmed key from the dealership.
