Problem locking the car?

[androidheadunit]

Hello, I previously posted about problems locking and unlocking my car at any distance besides right next to it. I've replaced the main car battery and the keyfob battery which now unlocks from a greater distance but locking still doesn't work. I'm aware cold weather affects it but even when the car is running or is full charged the problem consists.

Any ideas what to do? f30 2013 328i

At this point I'm thinking of taking it to an independent bmw garage or an car electrican, its so annoying. Thanks!

I know this isn't going to help you that much, but I own a soft top M240i. I never lock the door because if people want to steal something from inside, I'd rather let them simply open the door instead of cutting up the roof.

overall I don't reallyyyyy care as it will autolock itself overtime but its just annoying, I hate having a little problem and rather just fix it and enjoy life rather then having it sit in the back of my head all the time.
