Remote controls for car keys require a power source. Most car keys use batteries in the form of button cells for this purpose. However, some manufacturers such as BMW use rechargeable batteries in their remote controls. These batteries are permanently soldered to the circuit board and usually charge while driving. In case of a defective BMW battery, the car key owner cannot change the battery by himself. He must open the case, remove the defective battery and solder in a new battery.
To do this, you need some experience and dexterity to be able to perform a battery change for car keys. However, we will be happy to put you in touch with a car key repair service near you.
