Keyless sometimes not working

[Askandask]

I have BMW 740 2017, the buttons in the keyless remote are working fine but if I want to open/close the doors without using the buttons (keyless) most of the time not working.

I changes the batteries 3 times and still most of the times not working.


Any idea what would be the reason? I don’t want to go to the dealer because I know they will say replace the remote which it cost more than $400.

The car comes with two keys, one of them at home and the other one with me. As I said before, The key was working good but now most of the time I have to take the key from my bag and keep close to the door and then it work and sometimes not then I have to use the buttons to lock or unlock it.

not sure 100% , but sounds like it could be the car battery . so many electronics in these if the voltage is a little off stuff starts not working 100% and comfort access is normally the first thing to not work correctly
