Ignition Key Lock Cylinder
What is an Ignition Lock Cylinder and where is it Located?
The ignition lock cylinder is where it all starts – it’s the actual part that you insert the key into to power the vehicle. In addition, an ignition lock cylinder also serves as a vehicle’s most basic theft deterrent because it makes it harder for other people to drive it without the proper key having been inserted into it.
Your vehicle’s ignition key lock cylinder is mounted either in the steering column, on the dash, or the center console. Most ignition lock cylinders have four positions: off, accessory, start, and on. When you turn and hold the key at the “start” position, power is supplied from your vehicle’s battery to the starter motor to start the engine. Once started and the key is released, the key will then return to the “on” position as a result of the “start” position being spring loaded, power supply to the starter is cut, and this then allows for all of the vehicle’s electronics and accessories to be powered. The “accessory” position of the lock cylinder allows for power to be supplied to other accessories such as the radio without powering the components necessary for the vehicle to run. So while the ignition switch is essentially responsible for making the electrical connection that makes all of this possible, theignition lock cylinder is what actually gets it all started by activating the switch.
The lock cylinder is a fairly simple mechanical device. Within the ignition cylinder is a series of springs and different size tumblers; the notches of your key will line up with these tumblers. When the correct key is inserted, the cylinder is able to rotate within the housing, allowing for it to activate the ignition switch. Some applications have the lock cylinder and switch incorporated into a single unit rather than simply being connected to each other, and many vehicles use a small transponder chip inside the key as part of the vehicle’s anti-theft system. Vehicles that use these anti-theft key chips may need additional programming for the new lock cylinder to work and replacement is generally a bit trickier. Most ignition lock cylinders however can be replaced using simple hand tools and a little bit of mechanical ability.
Ignition Lock Cylinder Failure
A properly functioning ignition lock cylinder is often taken for granted, only to be thought of once it begins to cause issue. Lock cylinders can fail for a variety of reasons, including age and countless key cycles which can take their toll on the lock cylinder. Often, the tumblers can stick preventing the key from turning the cylinder, which may result in a bent or broken key. Other times the tumblers or the key can wear down allowing for the cylinder to turn freely which poses problems because in this case any key may be able to turn the cylinder, or you may be able to simply remove the key while the car is turned on. Attempted theft can also leave a cylinder inoperable or missing. No matter what the cause is, a malfunctioning ignition key lock cylinder can be a major inconvenience, and may result in an inoperative vehicle. It’s a wise move to address any problems with your lock cylinder before it leaves you stranded.
