How to add an additional master car key if a master key has been lost on Hyundai Sonata?

This procedure is used for adding an additional master key if a master key has been lost. It is necessary to have the ID key, identified by the Hyundai logo, to perform this procedure. If the ID key is lost, the procedure must be completed at a dealer service department or a repair shop equipped with a Hi-Scan diagnostic tool. For 2011 and later models, a Hi-Scan diagnostic tool is required to program the key(s) to the system. First, place the ID key into the ignition lock cylinder and turn it to the On position, then to the Off position. Within ten seconds, insert the key to be added into the ignition lock cylinder and turn it to the On position, then to the Off position; the new key is now registered to work with the immobilizer system. If another key needs to be added, repeat the previous step, noting that only two master keys can be registered.

Hyundai Sonata Car Key

With the Hyundai Sonata Car Key, drivers can quickly unlock their doors and start the engine. The first design for the famous Sonata in the Hyundai family was a metal-blade Car Key that turned the ignition switch and opened the lock. With technological advancement, a fob-based remote keyless entry Car Key appeared, which has extra buttons that allow doors to be secured or released from several yards away. The smart proximity Car Key was introduced in recent model years, which, when kept in a pocket, uses short-range radio signals to determine when the holder comes near, so the sedan can unbolt the doors automatically and allow push-button start. Each new model, as it was developed, required less effort: first twisting the cylinder, then pressing a button, and finally, no touch. Added layers of electronic codes provide added security against theft. No matter what type it is, the Car Key still opens the trunk and glove box and can be coupled with a valet variant that restricts access to the cargo area. Every current Sonata allows owners to store an uncut spare blank for quick duplication, with Hyundai continually improving security so Sonata drivers can enjoy easy yet safeguarded mobility.

If you are looking for affordable high-quality OEM Hyundai Sonata Car Key, then you have come to the prime place. Our website provides a large amount of genuine Hyundai Sonata Car Key at unbeatable prices. All our parts come backed with the manufacturer's warranty.
