Q: What Does a Tesla Car Key Look Like?
A: Tesla car keys come in two types: key fobs shaped like miniature cars and black key cards that fit easily in a wallet.

Tesla car key fobs resemble miniature versions of the car they control. Buttons can be used to open various parts of the vehicle, such as the doors or the front and rear trunks.

On the other hand, key cards are designed to fit in your wallet and can be used to unlock your vehicle. These key cards resemble standard-issue key cards, taking on a flat, rectangular shape, and are typically colored black.
How Does a Tesla Car Key Work?
Tesla key fobs work similarly to those used in other vehicles. Each key fob uses Radio Frequency Identification (RFID) to communicate with the vehicle’s receiver. Buttons are pressed to either lock or unlock the doors or the trunks.
Key cards work similarly at a much shorter range. Each key card also uses RFID technology to unlock the car doors. However, the key card must be brought close to a sensor on the door.
When passive entry mode is activated, the doors will automatically unlock, and the engine will start as soon as the fob or paired phone is within range of the vehicle. All of this happens without pressing a button or interacting with the key.
Some users recommend disabling this feature to secure the vehicle against theft.
