3. Broken Internal Components
If a remote is dropped frequently, internal solder joints can split. Particularly, the connections in between the battery terminal and the circuit board are susceptible to snapping, which cuts off power to the gadget totally.
4. Signal Interference
Periodically, the remote is perfectly functional, but external aspects avoid it from interacting with the car. Big power lines, radio towers, or even other electronic gadgets in a pocket can interfere with the RF signal.
