Step-by-Step Guide to Replacing Battery
Follow these steps to safely replace the battery in your Acura key fob:
1. Pop open the key fob casing
First, locate the small notch or slot on the side of the key fob. Insert a flathead screwdriver into this slot and gently pry apart the two halves of the plastic casing. This will expose the internal circuit board and battery.
2. Remove the old battery
Use the screwdriver to gently pry up the battery from its holder, being careful not to damage the copper contact points. Discard the depleted battery properly.
3. Install the new battery
Align the new battery’s positive + side facing up in the battery compartment, matching the original battery orientation. Firmly press it into place. Refit the two casing halves.
4. Reset and test the key fob
After reassembling the shell, press any button on the key fob to resynchronize it with your Acura. Test that the lock/unlock buttons work. If the car does not respond, you may need to reset by following the owner’s manual for your specific Acura model.
