Went to Tesla Service Center to replace my key fob casing. I get there. Find out that the extended service agreement doesn't cover warranty stuff. So okay I'm ready to pay the $10. She takes my key and brings it to the back for the guys to replace. It takes a good 15 mins.. then I see the guys come to my car to test.. and it seems like they're having issue with it. They go back in and the service rep tells me.. "your key is dead.." with a smile.. like I had handed her a dead key as a joke or something.. I'm like "I just used that to drive here from work 15 mins ago..and right before I got in my car I popped the trunk to open it" I told her it was working when I got in my car to get here.. and worked as I parked to walk into the store. She had insisted all they did was replace the casing and it's the same remote but it's dead.. but She made it seem like I knowing gave her a dead key or that it was already dead before I gave it to her. I had to leave for a doctors appointment I expected to pop in for 15-20 mins and ended up there for 45. She had said that they would look at the logs and see when the car fob was last used. I had to leave there using the app for keyless driving. But that's a pain in the ass waiting for the app to load. What should I expect? Will they replace the key fob if they find that I did indeed drive here with the key fob working and not keyless driving? I'm like what the heck it was working when I handed it to you and all I needed was to get a new casing because the button cover came off.
