The most common reasons include a blown fuse, poorly connected parts, and worn wires. Like all electronics, a fuse is present in the keyless system for safety purposes. If there is a high voltage on the ignition system end, the fuse will blow to protect the components from damage. It will disconnect the ignition system from the sensor.
