card key dimensions are 85.60 mm in length and 53.98 mm in width. The length-to-width ratio is 4:3, with a thickness similar to or slightly thinner than a credit card. Card Key: The Tesla Model 3 comes with two card keys. Swiping this card over the induction area below the B-pillar camera can unlock or lock the vehicle. The card key serves as a backup or can be used when carrying a phone is inconvenient. The disadvantage of the card key is that it's relatively easy to lose. Physical Key: The Tesla Model 3 and Model Y do not come with a physical key by default, but they are available for purchase on Tesla's official Taobao store and website. The physical key includes functions such as unlocking, locking, and opening the front/rear trunk. This key can be purchased separately and paired with the vehicle by the owner, which is much more convenient than traditional automakers that require visiting a dealership for key pairing.

I've always found Tesla's card key incredibly practical. Its dimensions match a standard card size, approximately 85.6mm long and 54mm wide. This compact size is so convenient—I always slip it into my wallet or pocket for easy carrying, without worrying about the bulkiness or clothes-scratching issues of traditional metal keys. The ultra-thin design aligns with Tesla's minimalist style—just a quick swipe near the B-pillar to unlock the car with lightning-fast response. The size clearly considers daily carry needs, allowing discreet handling in stores or other public settings. However, the small form factor may increase misplacement risks, so I recommend attaching a small labeled tape marker or pairing it with the mobile app's backup key function for added security. Overall, this portable design simplifies driving while reducing physical burdens.

The compact design also conserves resources, being eco-friendly and durable. However, protect it from moisture or magnetic fields, and use the app to quickly deactivate if lost. New owners should practice the tapping position. This minimalist approach simplifies life while aligning with modern lifestyles.

The card key measures 85.6mm by 54mm, exactly the size of a credit card. I've seen this specification allows easy integration of NFC chip communication.

Compared to the app key, it's more durable without signal dependency issues. The size selection emphasizes practicality while maintaining aesthetic appeal.

Last month during a trip, I stored it with my passport – a quick tap unlocked the car in seconds, saving both time and hassle. Its compact size makes carrying effortless, though it might occasionally slip out when bending over or kept in pockets, but it's usually retrievable. I recommend storing it in a fixed spot like a wallet to avoid the frustration of misplacement. This practical size truly enhances the overall driving experience.

The card key is fixed at 85.6x54mm with a credit card-style design, which I often use for secure and convenient access.
