How to Program Keyless Entry Remotes in a Hyundai Sonata

The keyless entry system in your Hyundai Sonata is part of the factory alarm system. If you have to replace a lost or damaged remote control, reprogramming will be necessary. The remote control is important because it not only locks and unlocks the doors, but also sets and disarms the factory alarm when you open or close your car doors. The new remotes are available at any Hyundai dealer. While they will program it for you, you can do it yourself and save a programming fee.

Step 1

Locate the fuse panel under the dash on the driver’s side of the car. Just below is the factory alarm system control module. Open the cover of the alarm system control module and locate the memory switch inside.

Step 2

Verify that the switch is in the “Off” position; if not, change it to the “Off” position. This is important so that the system understands what you want it to do when it goes into programming mode.

Step 3

Insert the key into your Sonata’s ignition and turn the key to the “On” position. Wait 60 seconds, then move the memory switch inside the control module to “Set.”

Step 4

Press and hold the “Lock” button on your remote for a full minute. This allows the remote control and the control module to communicate and synchronize. Release the “Lock” button and turn the memory switch on the control module back to the “Off” position.
