Opening the door of a 2021 Hyundai Elantra
 

The battery in the key fob of your new Hyundai vehicle should last for years, but you may have to open it once or twice if it stops responding. It’s a quick enough process, so our service team at Sid Dillon put together a quick and simple guide covering everything you need to know. Then be sure to check out our service department for all of your Omaha auto needs


How to Open a Hyundai Key Fob

First up, you’ll have to know how to open the Hyundai key fob. Here’s how that works:

  • For Newer Models: Remove the metal key in your key fob by pressing and holding the metal tab or button, then use it to open the back cover by inserting it into the small opening and turning it either direction.
  • For Older Models: Use a coin or a flat blade screwdriver to pop open the key fob from the small notch or indent along the outside.

You can now follow these steps:

  1. Carefully lift the circuit board to expose the battery.
  2. Check the battery type and buy a replacement – most Hyundai models use a CR2032 battery.
  3. Insert the Hyundai key fob battery replacement, ensuring as you do that all the appropriate connections are contacted by the new battery.
  4. If you needed to remove the metal key for a newer model, replace it when your key fob is back together.

How to Program a Hyundai Key Fob

Programming a Hyundai key fob is just as simple when you follow these steps:

  1. Get in your Hyundai and close all the doors.
  2. Use the key to turn your vehicle to the ignition’s “ACC” (accessory) position
  3. Hold the key fob’s “open” or “unlock” button until your vehicle’s light flashes.

Keep in mind that this only works when you’re replacing the old battery. If you have a brand-new key fob, drop by our Sid Dillon showroom to have it programmed.
