That must be new or I completely missed it when looking. For, likely, the last 10 or so years of working I had a security key card for access to where I worked at major corporations. They always provided a similar plastic holder and cloth-like neck thingie. I just put it in my wallet and, for the most part, just backed into the wall sensor. Worked fine. The problem I have with the M3 key cards is they are, essentially, the last resort to accessing your car. I don't view them as anything to be surrendered to valet parkers or service centers. I did purchase one key fob and put in in a "RoyalFox Genuine 3 Buttons Leather Key Fob case Cover for Tesla Model X, Car Remote Key Pouch Bag with Key Rings Kit Keychain Holder Metal Hook Black " which works great. On the key fob itself there is a pin where a wire loop connects to the ring for house keys etc. One click on the 'roof' locks the car, 2 clicks on the roof unlock. Pressing, and holding, the trunk opens the charge port, a quick press on the trunk or frunk opens them. Yeah, Tesla should have given 2 of them to purchasers with case.I got the "Seven Sparta Key Card Holder for Tesla Model 3 Silicone Key Chain(Black)" from Amazon. I just wanted some type of case to put the key card in when the car goes to the body shop for Due Bill paint repairs.
Probably always a good idea after the car has been out of your possession to check the devices authorized to access your car when you get it back.
My personal feeling is the RFID cards are the last line of defense, so to speak. I don't plan to give mine to anybody. Is it worth $150 for the option of keeping them with you at all times? That's a personal choice. Unless the mechanic knows about the RFID card sensor he will have trouble with it. The roof on the case is marked for lock/unlock. They will still have to dangle it on the area behind the cup holders. Either way, unless whoever wants to access your car knows how to access your car, it'll be painful. The place where I go that has a valet only I just leave the keyfob in the cup holder for him.Awesome idea - thanks for the tip.
Any recommendations on what "key" to leave the Tesla approved body shop - key card or key fob ?? I haven't decided yet, but they will have the car for about 2 weeks correcting the many paint defects documented on my "Due Bill".
