When we took delivery of our Model S Plaid last August, we were given two key fobs and two key cards. We use the key fob routinely, as the mobile key is too iffy to rely on consistently. Sometimes, though, the key fob will not start the car although it opened the door. When that happens, the mobile key does not start the car, either. We have to take a key card out of a wallet and rub it over the wireless phone charger pad to start the car. Sometimes this will happen at every stop on a multiple errand run.
We've owned an EV since 2015. It's hard to accept that seven years later, with two new EVs in the garage, we still find getting into and starting our cars something of a crap shoot. Only our 2018 Honda Odyssey always lets us in and starts up without a contest of wills.
