RE: Pushbutton
You can do it. You may have to take it out every once in a while. Mine has failed to recognize that my FOB was in the vehicle once and once to my wife. I got out of the car and looked at the FOB wondering if the battery had gone dead or not and got back in and it worked. The wife had to remove the button and use the FOB as the key. Replaced the button and it has worked for her since. I hear that there was a recall about such occurences but haven't been bothered enough to take it back. If it doesn't happen at the dealership, I doubt they would know what had happened either.
