Tesla provides you with two Model 3 key cards, designed to fit in your wallet. Model 3 reads a key card only when placed within very close proximity (a few cm) to one of its card readers. Card readers are located on the driver's side door pillar and on the center console. To use a key card to unlock or lock Model 3, position the card as illustrated and tap it against the card reader located below the Autopilot camera on the driver's side door pillar. When Model 3 detects the key card, the exterior lights flash, the mirrors unfold or fold (if equipped with the premium package and Fold Mirrors is on), and the doors unlock or lock.
