Kia Optima Ignition Switch

The Kia Optima Ignition Switch allows the driver to bring the sedan to life while controlling components and holding down the steering column. Early models of the sedan relied on a column-mounted Ignition Switch connected to a lock cylinder requiring the appropriate mechanical key for power to flow to the starter, fuel, and component circuits. It turned to ACC, ON, or START, routing battery current to each system. This traditional unit also locked the wheel and shifter in the OFF position to prevent theft. From the late 2000s, many versions of the Kia Optima were equipped with a push-button Ignition Switch coupled with a smart fob. The transponder code in the smart fob communicates with the computer, and if the brake is pressed and the gear selector is in Park position, the engine will start with a tap, leaving pockets empty of dangling keys. The push-button design eliminates fragile tumblers and reduces the likelihood of jamming, but both Ignition Switch types are subject to wear and tear, so there is the possibility of no-crank conditions or sudden shutdown if contacts become worn and fail during vibration. Whichever style is fitted, the Ignition Switch is the critical gatekeeper of the electrical power and engine operation for every Kia Optima, including the current Kia Optima lineup.

If you're in search of top-notch, reasonably priced OEM Kia Optima Ignition Switch, then you've found the perfect spot. Our website boasts an extensive inventory of Kia Optima Ignition Switch, all priced at the market's premier price.
