Fab key is less fabulous

Recently on a couple of occasions my Model S key failed to open the door, despite a new battery. I had parked in a parking lot with no wireless service. I had my cell phone but had turned off my cell data service. I had to turn on the cell data to get the Tesla app working. Once I opened the door and got into the car, I couldn't start the car. The car would't start as it failed to recognize the key. When I pressed the "start" on the app, it asked for Tesla password! I don't carry password around and had to go back to my office to get the password.
Why didn't the car recognize the key? (it recognized at other times) and open the door? Why didn't the engine start with the app?
Why can't the app connect with the car in the bluetooth mode? Does the bluetooth depend on the car being "ON"?
Has anyone else noticed this? I am concerned, as this requires carrying the password, having internet connectivity etc.

yes with both Fabs

1. In order to place the key in the cup holder, you should be able to get in. I have a problem, unless I carry a data phone and cellular data is activated. That's why a bluetooth connectivity could be better, particularly when you are just outside the car and are trying to get in and start.
2. Yes, it happened with both my keys. Both had replaced new batteries within the last few days (actually twice).















Oh Hell, that's too slow.

I do have my glucose monitor transmitter in my body but that is via bluetooth and shouldn't interfere.

This morning one of my fab got wet and I couldn't start the car. Unfortunately, I didn't have my p[hpne with me. I walked to my home (near by) and got the other fab-didn't work. Both with new batteries.
Brought back my cell phone, entered the car, started, and droove home.
Now both my fabs (only one got wet) don't work. Any soplutions, suggestions, reasons?

Hi
What do you do when you come back and the car doesnt recognize FAB and open the door? If yyou don't have Iyour phone/internet, you are helpless.
My Tesla does not recognize both my Fabs with brand new batteries. I can use my iPhone and open doors and start but need i9nternet. I wish the app would work independent of internet by hardwire or bluetooth connection.
I have no clue why my fabs don't work-tesla hasn't returned my call.

first off they are FOBs, secondly the design has little to do with owner foolishness.

I was not complaimning about the design. Rudeness has no place in the forum. Read the post before you reply. I suppose that you had never misplaced, damaged anything in your life.

To the OP: you already have a topic about problems with your key fobs (they are not called a "fab") that you started in February here: Fab key is less fabulous and you just made the same post in that thread.

Thank you. Here, the point was one of my Fab got wet and both stopped working. I was not rude, annoyed, and was on;ly asking for solutions and suggestions.
