What to Do When the Spare Car Key Won't Start the Engine?
1 Answers
Here are the solutions when the spare car key fails to start the engine: 1. Check if there are any signal interference sources around the vehicle, such as a wireless MP3 player, and unplug it if present; 2. When inspecting the vehicle's wireless signal issues, determine if any wireless signal devices have been installed; 3. The issue might be due to insufficient battery power—try replacing the battery. Alternatively, the circuit board inside the key might be faulty, requiring repair at a service center. A car key is a tool used to start and operate the vehicle. Modern car keys use chips as part of a magnetic chip system. The ignition lock cylinder's reading coil will scan the key's chip, which contains fixed digital information.
