How long does the new car key battery need to replaced?

The battery of the remote control key of the car can be used for about two to three years under normal circumstances. When the power is out, it can be replaced by after sales.
1. In general, the remote control key will not suddenly run out of power, but will be indirect. You can only open the door when you find that you need to be very close to the car, or there is no response when you press the key several times, then you should consider changing the battery.
2. If the time limit is exceeded, the signal is likely to be weak, but the specific time of power consumption is also related to the storage at ordinary times. For example, if we put it close to the mobile phone or computer TV, the battery will consume a lot, because it will send some electronic waves to the outside at any time.
3. The car key is not a secret accessory, the battery is our common button battery, but improper operation will cause circuit board damage, please be careful operation.

Everyone knows that the brake pads must be replaced when they are worn out, but if they are not found in time to continue using the car, they will wear out the brake disc as well. The brake pads are fixed...
