Key fob buttons don't work

[red914]

I have a 2009 135i with convenient access and 2 fobs. One fob is 100% functional. The second fob works for convenient access (unlocking/locking doors by touching door handle, starting engine, trunk, etc) but if I use the buttons nothing happens. I have replaced the battery. Not one button works, even standing right next to the car.

Any ideas?

I have yet to dismantle the fob. Perhaps the button contacts are dirty but it is surprising to me that none of them work at all.

Thanks!

Replace the remote.

Did you wash the fob with your clothes ? It happens.

Put the key fob in a jar with some dry rice... put the lid/top on and let it stand over night. Then try the fob. The rice will absorb any water inside the key fob.

Otherwise your gonna need a new fob at ~$400.

No I did not wash it or in any way get it wet but I am also not the first owner so who knows what happened in the past. I can try the rice thing but at this point it has been like this for at least 7 months so it is likely far too late for that to do any good. I might try taking it apart to see what the button contacts look like.

It's definitely not worth $400 for me right now. I am the only driver so I only really need the one fob; the other is basically a backup and it still does the most important things.
