How can I replace the car key button battery without going to the 4S store

The car owner went to the 4S store and was told that the car key didn't have a signal because the battery was out of power. It cost more than 100 to replace a small battery. Later, he checked the price of the small battery CR2032 on the Internet, and could buy a board for 20 yuan. There were about six different models. After all, the service at the 4S store was very good, but it was really expensive. Can we replace the battery of the car key ourselves?

Of course, it is possible, and it is not difficult to replace the car key battery, as long as you master the skills, it is very simple. Generally, the mechanical key rod hidden in the smart key may be the tool to open the car key housing. We should carefully observe the structure.

In addition, the common button batteries cr2025 and CR2032 are relatively easy to obtain in the market. Today's advanced smart remote keys cannot resist strong collisions and knocks. The car keys are integrated with ceramic chips and induction coils with different functions. Their common problem is that they are fragile. The ceramic structure will make them more vulnerable to damage. Therefore, we should treat our car keys well in the process of use.
