Can the Chery Tiggo 8 use a mobile app to replace the key?

Chery Tiggo 8 cannot use a mobile app to replace the key. Currently, in terms of mobile security, it does not support replacing the remote key. It may gradually be replaced in the future. Concept of car keys: A key refers to a tool for unlocking. A car key is a tool for switching the car on and off. Modern car keys use chips, which are part of a magnetic chip system. The ignition lock cylinder's reading coil reads the key's chip; each chip has fixed digital information. Advantages of remote keys: Remote keys allow unlocking and locking the car from a distance without inserting the key into the lock. The biggest advantage is that, regardless of day or night, there's no need to locate the lock hole—unlocking and locking can be done conveniently from a distance. The key emits a weak radio wave, which is received by the car's antenna. The electronic control unit (ECU) identifies the signal code, and the system's actuator (motor or electromagnetic coil) performs the lock/unlock action. The system mainly consists of a transmitter and a receiver.

What is the reason for slight body shaking after replacing the outer CV joint?

Go to the repair shop to check if the chassis components are not securely fastened. Introduction to outer CV joint: The constant velocity joint, commonly known as the CV joint, is divided into inner and outer CV joints. A steel shaft connects the inner and outer CV joints, collectively called the driveshaft. As the name suggests, it is a rotating shaft that transmits power and ensures equal speed transmission during steering. Its faults can be identified by sudden acceleration and turning maneuvers. Lifespan of outer CV joint: It can last over 200,000 kilometers. However, if the dust cover of the outer CV joint is damaged during vehicle maintenance, allowing large amounts of dust to enter the joint while driving, its lifespan may be reduced to just a few months. Therefore, it is essential to regularly inspect the CV joint dust cover for damage.

Should I Replace My 7-Year-Old Car?

For cars that have been driven for seven or eight years, as long as they haven't been involved in major accidents, they are generally still drivable. Whether you need to replace it depends on your personal financial situation or usage needs. Conditions for Replacement: From an age perspective, the car can still be driven. However, if the mileage is too high and the condition isn't great, and your financial situation allows, then you can consider replacing it with a new car. Replacement Advice: Unless you absolutely must replace it, it's better not to change a car that's only been driven for six or seven years. Although cars are relatively affordable now, upgrading to better configurations still requires a down payment of tens of thousands, and buying a new car outright costs hundreds of thousands. It might be wiser to save that money for other purposes. After all, a car is just a means of transportation—as long as it runs and has air conditioning, that's sufficient.
