Under normal circumstances, the lifespan of a standard remote car key is typically 2-3 years, depending on the actual frequency of use. Different car models may also vary, making it difficult to determine the exact replacement time. If the owner uses the car key more frequently, the battery can be replaced earlier. Method for replacing car key battery: First, pop out the key head and locate the side with a notch, which is where the battery cover can be opened. Precautions for using car keys: Do not place the car key together with electronic devices that emit radiation.

What Causes the Squeaking Sound When Opening the Car Door?

Squeaking sounds when opening the car door are mainly caused by wear and deformation of the door hinges and limiters, as well as dust and dirt adhering to the gaps. Due to years of opening and closing, the door hinges and limiters are prone to wear, and dust can accumulate inside, leading to vibrations and noise during the door operation. Over time, the door hinges may rust or deform. After cleaning the grease and dirt from the surfaces of the door hinges, limiter arms, limiter pins, and connecting brackets, it is advisable to apply a specialized lubricant for lubrication. The door and body are connected via hinges, and it is normal for hinges to produce noise after prolonged use. It is recommended to apply lubricant every 2 to 3 months for regular maintenance.

Can 98 and 95 be mixed?

It is best not to mix 98 and 95. It is better not to mix different grades of gasoline. If the owner previously added 98 gasoline, the next time they refuel, they should also add 98 gasoline. In special circumstances, adding 95 gasoline once is not a big problem, but doing so for a long time will cause engine knocking, increase engine carbon deposits, and increase fuel consumption. If the owner wants to change the gasoline grade, it is best to use the gasoline in the car's fuel tank until the fuel gauge light comes on before refueling, or directly extract it and then switch to another grade of gasoline, rather than mixing them directly.
