Such interference can impede the smooth rotation of the key, causing frustration and potentially leaving you stranded.

Some days it starts without a hitch, while on other occasions, it stubbornly refuses to cooperate.

The electrical signals required to initiate the engine’s ignition process might not be consistently reaching their intended destinations, resulting in sporadic starting problems.
