Recognizing a Dying Key Fob Battery

Before you go through the hassle of replacing the battery, let’s make sure that’s truly the problem. Here are some telltale signs that your 2003 Hyundai Elantra GT key fob battery might be on its last legs:

Decreased Range: Do you find yourself standing closer and closer to your car to get it to unlock? A weak battery often results in reduced signal strength.
Intermittent Functioning: Is your key fob working sporadically or only at certain angles? This inconsistency can indicate a dying battery.
No Response: This one’s pretty obvious. If pressing the buttons on your key fob elicits absolutely no response from your car, a dead battery is the most likely cause.

Replacing the battery in your 2003 Hyundai Elantra GT key fob is surprisingly simple. Just follow these easy steps:

Gather Your Tools: You’ll only need a few things: a small flat-head screwdriver and a replacement CR2032 battery (easily found at most supermarkets, electronics stores, or online).
Open the Key Fob: Locate the small groove or notch on the side of your key fob. Gently insert the flat-head screwdriver and carefully pry open the casing. Be careful not to force it.

Reassemble the Key Fob: Carefully align the two halves of the key fob and press them together until you hear a click, indicating it’s securely closed.
