Understanding Your Key Fob
The Ford Mustang remote key fob from 1994 to 2009 comes in two versions: a four-button and a three-button variant. Regardless of the version you have, the process for replacing the battery is the same. The key fob is designed to be durable, but over time, the battery will need replacing.
Tools You Will Need
- Razor blade
- Small flat-head screwdriver
- CR2032 coin battery
These tools are essential for safely opening the key fob and replacing the battery. You can find the CR2032 coin battery easily online or at a local store.
Step-by-Step Battery Replacement
Step 1: Identifying the Separation Line
First, examine the edges of your key fob. You will notice a line running around the perimeter. This is where the two halves of the key fob separate. The key to accessing the battery is to carefully open these halves.
Step 2: Scoring the Edges
Take your razor blade and gently score along the separation line. This will help in creating a gap for leverage. Be cautious while doing this to avoid damaging the internal components.
Step 3: Finding Leverage Points
The best place to start leveraging is near the keychain attachment point at the top of the fob. Continue scoring around the edges until you can insert a small flat-head screwdriver into the gap.
Step 4: Prying Open the Key Fob
Once you have a gap, use the flat-head screwdriver to gently pry the two halves apart. You may need to score a bit more around the edges to fully separate the fob. Be patient and work slowly to avoid breaking the plastic.
Step 5: Accessing the Battery
After prying open the key fob, you will see the circuit board and the battery. The battery is usually on the side without the circuit board. The negative side of the battery, which lacks lettering, should be facing up.
Step 6: Removing the Old Battery
Use the small flat-head screwdriver or a paperclip to gently lift the old battery out of its compartment. Be careful not to damage any surrounding components.
Step 7: Inserting the New Battery
Take your new CR2032 coin battery and place it in the compartment with the positive side (the side with lettering) facing down. Ensure it is seated properly.
Step 8: Reassembling the Key Fob
Once the new battery is in place, snap the two halves of the key fob back together. Make sure they are securely attached and there are no gaps.
