Tesla does have a key. Here are the features of Tesla: 1. Ultra-long driving range; 2. Multiple charging methods; 3. Tesla's autonomous driving. Taking the 2021 Tesla Model S as an example: 1. Body dimensions: length 4975mm, width 1964mm, height 1445mm, wheelbase 2960mm, trunk capacity 793l, curb weight 2069kg. 2. Power: The 2021 Tesla Model S is equipped with a rear permanent magnet AC motor, with a maximum horsepower of 617ps, maximum power of 493kw, maximum torque of 755nm, matched with a 1-speed fixed gear ratio transmission.

I've been driving a Tesla for several years, and it completely lacks the traditional metal key fob. It primarily relies on the Tesla App as the main key: after downloading the app and logging into your account, the car automatically senses and unlocks. You just step on the brake to start driving—super convenient. They also provide a key card, about the size of a credit card, which you tap on the B-pillar to unlock the door, perfect for emergencies. If you opt for the top-tier version, you can purchase an additional remote key fob, which looks like a small square. However, I usually depend on the phone app—it allows remote activation of the air conditioning to preheat the car or check its location, which is incredibly practical. Tesla's digital key system represents a major advancement in automotive technology, reducing the hassle of physical keys and being a bit more environmentally friendly.

As a Model Y owner, using the Tesla key is super convenient in daily life. The main feature is the mobile app control: the car door unlocks as you approach, and it starts as soon as you turn the steering wheel after sitting inside. I keep the key card in my wallet as a backup, and if there's an issue with the app, I just tap it on the B-pillar. The Tesla key design is simple and efficient, and the app also allows setting who has driving permissions or remotely locking the car, eliminating the hassle of finding a physical key. Occasionally, when a friend borrows the car, I can easily share temporary access via the app—it's incredibly effortless. The era of smart keys is truly amazing; once you've experienced it, there's no going back.

Tesla's Digital Key System: The core is the Bluetooth-enabled mobile app, which allows automatic door unlocking via near-field connection, supplemented by an encrypted key card as a backup. From a security perspective, it's excellent—the app requires a phone password or biometric authentication to unlock, reducing theft risks. If the card is lost, it can be deactivated and reissued to prevent misuse. A potential concern is the possibility of hacking, but Tesla employs robust encryption technology, making it more secure and harder to replicate than traditional keys. Owners are advised to secure their devices with locks to ensure account safety and peace of mind.
