Step 1: Find the notch to open the fob
This is the trickiest part because the notch may not be obvious. On some units, there’s a small gap at the top, but for others, you might have to inspect the connection point where the emergency key slides out.

Step 2: Use the screwdriver to pop it open
Slide the flat-tipped screwdriver into the slot and wedge it open. The whole unit should open in half down the middle, revealing a round battery inside.

Step 3: Identify the battery type
Look closely at the battery inside and look for markings on it that will reveal what model the battery is. Buy a brand-new battery of the same kind.

Step 4: Replace the old battery with a new one
The old battery should come out with ease if you pop it out with your finger. The new battery slides right in where the old one was.

Step 5: Snap the fob shut
Now that you have a new key in place, you can close up the key fob. It should click back into place when you squeeze it.
Depending on the quality of the replacement battery you purchased, how often you drive, and if the battery is a proximity key that drains quicker, you might have to replace the battery every five years or so.
