Can it be equipped with a car remote control?
It can be equipped, but it depends on the complexity of the car anti-theft system. Remote control prices may vary. The car remote control key not only has remote control function, but also has anti-theft function. Each remote control key will have a “password”, and this “password” will also be in the car’s anti-theft system.

After the matching is completed, the new remote control key can be activated, and the lost key will become invalid immediately. Even if someone picks up your lost key, he can only open your car door through mechanical unlocking, but it is impossible to start your vehicle.
It is relatively complicated to match a car remote control key. Both 4S shops and large repair shops can do it. The difference lies in the price. Maintenance shops outside can basically cost a few hundred yuan. The price of a 4S shop is It usually costs about a thousand yuan, and it also takes some time.

Car remote control battery
Car remote control battery model
1. Button-type CR2016 model battery
It is used in today’s car key remote control The efficiency is very high and it is almost one of the most versatile car remote control batteries. The battery voltage of this type of battery is 3V. Generally, car key batteries use 9V for power supply, so all three batteries must be replaced every time the battery is replaced. Such as: remote control for Guangmoto, Toyota, Volkswagen, Mazda and other models. CR2016 specifications are: battery diameter is 20mm, thickness is 1.6mm.
2. Button-type CR2025 model battery
The usage rate is much lower than CR2016. But some car keys will still be used. The thickness is relatively thicker than that of 2016, but the power storage is relatively high. CR2025 specifications are: battery diameter 20mm, thickness 2.5mm. This type of battery is also commonly used in audio remote controls.
3. Button-type CR2032 battery
The voltage is also 3V, but the capacity is about 200mah, so its thickness is twice that of CR2016;
