Step-by-Step Guide
Let’s dive into the process of replacing your key fob battery.
1. Identify the Key Fob Type
First, ensure you have the correct key fob. The 2010-2014 Ford Mustang uses a rounded smart key. Confirm this before proceeding.
2. Locate the Split Line
Examine the key fob closely. You will notice a line running around the middle, indicating where the key fob splits apart.
3. Score the Edges
Using a razor blade, carefully score the edges of the key fob. This helps in separating the two halves. Take your time to avoid damaging the fob.
4. Create Separation
Once scored, use a small flathead screwdriver to gently pry the two halves apart. Start at the top where you would attach a key ring. This spot usually offers the best leverage.
5. Open the Key Fob
Continue working your way around the key fob, gently prying it open. Be patient and avoid forcing it. The key fob will eventually pop open.
6. Remove the Battery Cover
With the key fob open, you will see a small battery cover. Remove this cover to access the battery compartment.
7. Replace the Battery
Remove the old CR2032 battery. Note the orientation of the positive side, which should be facing up. Insert the new battery with the positive side up.
8. Reassemble the Key Fob
Replace the battery cover and ensure it is securely in place. Align the two halves of the key fob and press them together until they snap shut.
