Why Does My 2006 Toyota Camry Key Fob Keep Unprogramming?

Faulty Ignition Switch: Problems with the ignition switch can sometimes prevent the key fob from communicating properly with the car’s computer, leading to unprogramming.
Wiring Issues: Damaged or corroded wiring in the car’s electrical system can disrupt the connection between the key fob and the car’s computer, resulting in unprogramming.
