Help with RFID card

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

Suggest you log a service fault within your app so that you are in the que. You can always cancel if a solution is uncovered.

Sounds like the card is unserviceable - if you request service in the app they should replace it under warranty.

The "Unknown Key" thing is normal, at least for the keys that come with the cars delivered this year.
"Unknown Key" is the default name for a key. Go into the key screen and rename it. The second key that does not work is defective. Tesla should replace it or buy a new key pack of 2 from Tesla for $35 US

I had this issue in my car for about the first year of ownership. Renaming the cards in the menu made no difference, nor did deleting them and adding them back. I think a software update at some point fixed it, I haven’t noticed the problem since.
 
I booked a mobile visit on the weekend. They messaged me Monday morning to say that supplying a new card was not a problem. Hopefully they will save the mobile person a drive and just post it. However, the appointment is still there so we'll see. Anyway, prompt, efficient and effective service!
