When the ignition switch is turned to lock, the electrical power from the battery is cut off from the engine. The electrical circuits that power components such as headlights and radios are also turned off. Finally, a mechanical device called a neutral safety switch that prevents a car from being started unless it’s in “park” or “neutral” positions is activated.
The act of locking the ignition is a form of security for an automobile. It prevents someone from stealing the car by hot-wiring it. Locking the ignition, or locking the engine open, is accomplished by engaging the brake pedal and turning the key to the lock position. This locks not only the starter but also any door that may have been left unlocked before driving off.
A person can know their ignition switch is locked when they turn the key in the ignition and the car does not start. When the key is turned, if there is a click noise it indicates that the switch is in a position that locks or unlocks the steering wheel.
The car key is turned on when the key is inserted into the ignition and then rotated. The turning of the key activates a switch that sends a signal to the starter motor and initiates cranking. The starter motor’s job is to spin up the engine, which in turn begins spinning its pistons, creating compression and drawing fuel from the gas tank.
The four positions in the ignition switch are ON START, OFF STOP, ACCESSORY and RUN. When the key is placed in ON START, the engine starts and can be turned off by pressing and holding the button on the electronic device. The OFF STOP position shuts off the engine and stops battery usage when not in use. The ACCESSORY position switches certain devices such as electronic cigarette chargers on and off. The RUN position shuts down all non-essential electrical components to conserve energy.
The term “steering wheel lock” refers to when a driver cannot rotate the steering wheel at all. This problem can be caused by a variety of factors, such as a failed turn signal switch, a faulty bearing in the steering column, or a defective power-assisted rack and pinion module. The specific cause of the steering wheel lock will dictate the appropriate course of action for correcting it.
If you notice that your car key isn’t turning in the ignition, you may want to take it to a locksmith or auto mechanic. It is possible for this to indicate a problem with the lock cylinder. The lock cylinder is usually composed of many small pins which are connected with springs which rotate when the key is inserted.
