What car uses a card-style key?
2 Answers
The backup unlocking key for the Tesla Model 3 is a card resembling a bank card. The Tesla Model 3 does not come with a traditional car key but instead utilizes a smartphone for control. Below are some relevant details about Tesla: 1. The Tesla Model 3 is positioned as a mid-size sedan. It features a 4-door, 5-seat sedan design with no exhaust pipe at the rear and a front-mounted trunk. The car is equipped with a single-speed transmission delivering 462 horsepower, a total motor torque of 639 Nm, and a maximum power output of 340 kW, achieving 0-100 km/h acceleration in just 5.6 seconds. 2. At startup, the Model 3 has a creep function that allows it to move slowly without pressing the accelerator. Combined with a finely tuned accelerator pedal, it helps drivers precisely control power output, making it very user-friendly for beginners. During low to medium-speed driving, the Model 3's motor noise is exceptionally well-suppressed, with almost none of the annoying 'whistling' sounds common in ordinary electric vehicles. 3. The Model 3 employs an EPS electric power steering system with two main features: variable damping and variable steering ratio. While these features may not be considered cutting-edge technology today, Tesla engineers have finely tuned the entire system to be very linear and smooth. Tesla also provides a 4-year or 80,000 km vehicle warranty and an 8-year or 192,000 km battery warranty.
As an ordinary person who has driven for several years, I find the card car key incredibly convenient. It's like a credit card-sized smart key, commonly used in premium models from Mercedes-Benz, Tesla, and Lexus. I once drove a Mercedes-Benz C-Class, and the card key could simply be kept in my wallet—just a light touch near the door would automatically unlock it, saving me the hassle of digging through pockets for keys. When shopping or working with lots of items, this small design is particularly thoughtful, unlike traditional keys that might tear pockets. However, you must be careful not to lose it, as it can be tricky if it falls inside the car and locks you out. This feature is becoming more common, mainly in luxury brands pursuing a tech-savvy image—like the Tesla Model 3, which popularized it—but it's still rare in mid-range or budget cars. Overall, it enhances quality of life, and I recommend considering it when choosing a car.
