Is there a way to reset an LCD screen?
If set by a pot adjust the voltage through the entire range to see if the lcd character matrix/dots become visible. Standard HD44780 displays dont have a hardware reset pin. They can be reset in software, but that should not be necessary as they are reset when power is switched on.
What should I do if my ignition switch is not working?
How To Fix It: After ensuring the rest of the electrical system is intact, such as fuses, relays, and circuits, replace the ignition switch. The transponder antenna surrounds the ignition cylinder. If it doesn’t recognize the transponder key, it doesn’t allow the engine to run.
What happens if you have an incorrect ignition code?
The chip in the key transmits a specific code, of which there are millions. If this code matches the ones programmed into the vehicle, engine starting is enabled. An incorrect key code, such as from an unprogrammed key or damaged key, would prevent engine starting. Code “confusion,” such as having multiple keys can also occur, preventing ignition.
