You need to contact Tesla's after-sales service department and provide the vehicle's user manual and vehicle registration certificate for replacement. The replacement process takes approximately 30 working days. Below is additional information about Tesla: 1. Introduction: Tesla is an American electric vehicle and energy company, primarily manufacturing electric vehicles, solar panels, and energy storage equipment. The company's headquarters is in Palo Alto, and it was founded on July 1, 2003, by Martin Eberhard and Marc Tarpenning. The company was named Tesla Motors at its inception to honor the physicist. 2. Tesla Card Key: Owners typically use a smartphone app to unlock the Model 3, while the backup key is a credit card-sized plastic card. If the smartphone app is unavailable, the owner's phone is lost or out of battery, the card can be used to swipe the front door handle to enter the vehicle and then start the ignition.

I've talked to a few friends who drive Tesla Model 3 about this, and replacing a lost or damaged card key isn't actually too troublesome. First, you need to contact Tesla Service Center, such as making an appointment through the mobile app or official website. They'll help you order a new card, which typically costs a few hundred to around a thousand yuan, depending on the model. After receiving the new card, you'll need to pair it using the car's system by opening the key settings in the Tesla App and following the step-by-step instructions, which takes about 10 minutes. Don't forget that keeping a backup phone key is very useful—if you lose the card, you can still unlock the car with your phone. The whole process might take a day or two, so it's advisable not to wait until an emergency. Taking action early can prevent inconvenience when you're out and about.

What to Do When the Car Electronic Lock Doesn't Work?

Solutions for a car electronic lock that doesn't work: 1. The battery might be dead—replace the battery; 2. The car might be in a strong magnetic or electric field environment, which can interfere with the electronic lock's signal, causing it to malfunction; 3. The remote control buttons might be damaged, or there could be a circuit issue. Remote control keys have a limited lifespan, so button or circuit damage can affect normal operation—replace the remote control; 4. There might be an issue with the internal motor or wiring of the electronic lock, requiring professional repair. Car electronic locks come in various forms, including electronic key-type locks, button-type locks, and touch-type locks. Currently, the most common is the electronic key-type lock, which contains an electronic circuit inside the key that stores a password and communicates with the main control circuit through various means such as light, electricity, and magnetism.

What is the reason for the slight friction sound when turning the steering wheel of the Mistra?

The reasons for the slight friction sound when turning the steering wheel of the Mistra are as follows: The friction sound when turning the steering wheel is due to the fixed bracket connected to the steering wheel. When the steering wheel turns, it must rotate against the fixed bracket behind it, which requires bearings to complete. The sound is generated by the friction between the two disc-like bearing surfaces due to insufficient lubrication. Adding some lubricating oil can solve the problem. Relevant information is introduced as follows: When turning, avoid turning the steering wheel to the extreme, which can to some extent protect the steering wheel. At the same time, the owner should regularly check the tie rod to effectively reduce minor faults such as steering wheel vibration.
