Tools You’ll Need
Before you begin, gather the following tools:

Identifying Your Citroen C4 Key Fob Type
The first step is to identify the specific type of key fob you have. There are two common types:
- Type 1: This type has a single button on the key fob, typically a “lock” button.
- Type 2: This type has multiple buttons, usually including “lock,” “unlock,” and “trunk release.”
The process for changing the battery may vary slightly depending on the type of key fob you have.
Changing the Battery in a Type 1 Key Fob
Here’s how to change the battery in a Type 1 Citroen C4 key fob:
1. Locate the seam: Look for a small seam or groove running around the perimeter of the key fob. This is where the key fob will split open.
2. Insert the screwdriver: Gently insert the flathead screwdriver into the seam. Be careful not to apply too much force, as you don’t want to damage the key fob.
3. Pry open the key fob: Using the screwdriver as a lever, carefully pry open the key fob along the seam. You should hear a slight click as the two halves separate.
4. Remove the old battery: The battery will be visible inside the key fob. Carefully lift it out of its housing.
5. Insert the new battery: Align the new CR2032 battery with the positive (+) and negative (-) terminals inside the key fob. Gently press the battery into place.
6. Close the key fob: Once the new battery is secure, snap the two halves of the key fob back together. You should hear a satisfying click as the two halves lock together.
Changing the Battery in a Type 2 Key Fob
Changing the battery in a Type 2 Citroen C4 key fob is very similar to the Type 1 process, but with a few minor differences:
1. Locate the seam: Look for a small seam or groove running along the side of the key fob.
2. Insert the screwdriver: Gently insert the flathead screwdriver into the seam.
3. Pry open the key fob: Using the screwdriver as a lever, carefully pry open the key fob along the seam. It may take a little more effort to open this type of fob.
4. Remove the old battery: The battery will be visible inside the key fob. Carefully lift it out of its housing.
5. Insert the new battery: Align the new CR2032 battery with the positive (+) and negative (-) terminals inside the key fob. Gently press the battery into place.
6. Close the key fob: Once the new battery is secure, snap the two halves of the key fob back together. You should hear a satisfying click as the two halves lock together.
Troubleshooting Tips
If you’re having trouble changing the battery, here are a few troubleshooting tips:
- Check the battery type: Make sure you’re using the correct type of battery (CR2032). Using the wrong type of battery can damage the key fob.
- Use the right tool: Using a screwdriver that is too large or too small can damage the key fob. A small flathead screwdriver is the best choice for this task.
- Be patient: If the key fob is difficult to open, don’t force it. Gently apply pressure and work your way around the seam.
- Consult your owner’s manual: Your Citroen C4 owner’s manual may have specific instructions for changing the battery in your key fob.
Testing the New Battery
Once you’ve replaced the battery, it’s important to test it to make sure it’s working properly. Try the following:
- Press the buttons: Press the “lock,” “unlock,” and “trunk release” buttons (if applicable) to see if they are working.
- Test the keyless entry: If your key fob has keyless entry, try unlocking and locking your car to see if it responds.
- Check the range: Walk away from your car and see how far you can go before the key fob stops working. The range should be at least 10-15 feet.
Key Fob Battery Life and Maintenance
A new CR2032 battery should last for several months, but the exact lifespan will depend on how often you use the key fob. Here are a few tips to help extend the life of your key fob battery:
- Avoid extreme temperatures: Heat and cold can shorten the lifespan of a battery. Try to keep your key fob out of direct sunlight and extreme temperatures.
- Don’t leave the key fob in the car: If you leave your key fob in the car, it will be exposed to extreme temperatures, which can drain the battery faster.
- Replace the battery regularly: Even if the key fob is still working, it’s a good idea to replace the battery every 6-12 months to ensure optimal performance.
Beyond the Basics: When to Seek Professional Help
While changing a key fob battery is a simple task, there are times when it’s best to seek professional help. Here are a few scenarios where you should contact a Citroen dealership or a qualified automotive locksmith:
- The key fob won’t open: If you can’t open the key fob to access the battery, it may be damaged. A professional can help you open the key fob safely.
- The key fob doesn’t work after replacing the battery: If you’ve replaced the battery but the key fob still doesn’t work, there may be a more serious problem with the key fob or the car’s electronics.
- The key fob is damaged: If the key fob is cracked, broken, or water-damaged, it may need to be repaired or replaced.
