This is my 5th complaint and involves, again, the key card. This is the used key card the El Paso Tesla Dealer was kind enough to give me, and help me program, when one of the original key cards, less than a year old, stopped working. (Tesla wanted me to pay $45 for 2 new key cards) The used key card stopped functioning so I planned to call Tesla and have them ‘reprogram it’…something that must be done while I am in the car. I went on a last-minute trip and took my spare, barely-used key card. I also had my phone but didn’t realize I’d not re-downloaded the Tesla app when I recently troubleshot my phone. Later in the day I parked at CIty of Rocks State Park in NM, still without connectivity, and locked the car with the ‘good’ key card. Then I misplaced the key card! I called one of my 2 backup drivers and asked her to unlock and start my car for me. Her App did not allow her to do so, even though it showed the location of my car at City of Rocks…it said ‘move closer to the car’. (She lives in CA). I had to get a ride to Wifi, download the Tesla App, and when I tried using it to unlock the car, it said ‘you must be closer to the car’. When I got to the car, I was able to unlock and start it using the phone key. After arriving home, I used my App to get Roadside assistance and asked for a phone call when they texted to confirm my location. I explained that I didn’t need service, just needed help re-programing my defective card. (I had since found the good card!) The woman on the other end was helpful but it was difficult for her also. We ended up removing the defective key from my profile, though it required a lot of work and also required the ‘good’ key card. I have to call Tesla on Monday (it was Sunday) to get the card re-programmed. Had my difficulty been in a high-traffic or unsafe area I would have been in trouble. The ‘backup’ drivers on my App are there for emergency access to my car, supposedly from any location.
