Step-by-Step Guide

Follow these steps to replace the battery in your Acura TLX key fob:

Remove the Internal Key

The first step is to remove the internal key from the key fob. Flip the key fob over and locate the small lever. Push the lever up while holding it, and then remove the internal key.

Open the Key Fob

Next, you need to open the key fob. Flip the key fob to the back and find the space between the metal keyring and the edge of the back cover. Insert the flat-head screwdriver into this space.

Push the screwdriver down until it feels secure. Once it’s in place, twist the screwdriver gently but firmly until you hear a pop. This action will create an opening in the key fob.

Separate the Key Fob Halves

With the initial opening made, insert the screwdriver further into the gap. Twist it all the way down to separate the two halves of the key fob completely.

Remove the Old Battery

Now that the key fob is open, you can remove the old battery. Use the corner of the flat-head screwdriver to get under the battery. Gently twist the screwdriver to pop the battery out.

Insert the New Battery

Take the new CR2032 battery and ensure the positive side with the text is facing up. Position the battery into place and click it down securely.

Reassemble the Key Fob

After the new battery is in place, reassemble the key fob. Align the two halves and click them back together. Finally, insert the internal key back into the fob.
