Have had the 3LR for about 6 weeks. When I picked it up, Tesla gave me two RFID cards and we set it up on my phone. I subsequently successfully added my wife's phone. Once or twice, my Tesla phone App has not been running and the car has asked me to use the RFID key and this has worked fine. I have named that key. However, I note that when I use it to unlock the vehicle, it is described in the car control screen as "Unknown Key" even though it seems to work fine.
However, yesterday, the time came to use the second key and it does nothing. It does not unlock the vehicle and if the vehicle is unlocked and I try to drive, swiping behind the cup holders does nothing. I tried to name what seems to be this second key. That works but the key still does nothing. So I tried deleting that key, which is also described as "Unknown key" using the other (first) key and that worked. Then I tried adding back that second key but the car does not detect swiping it. So, it seems this second card is defective in some way even though it looks in perfect condition with no damage.
Is there some special step I have missed in trying to get this key to work or does it seem like it has just failed in some way and the car RFID readers just cannot "see" it?
Also, is it normal for these cards to be listed as "Unknown key" on the car screen?
Thanks for any assistance,
Dave
