Gather Your Supplies
Before you begin, ensure you have the following:
- New CR2032 battery: This is the type of battery used in most Audi A5 key fobs. You can find these at most electronics stores or online.
- Small flat-head screwdriver: This is needed to pry open the key fob.
- Optional: A small, non-metallic object: This can be helpful for pushing out the old battery.
Identifying Your Key Fob Type
Audi A5 key fobs come in various designs, but the battery replacement process is generally similar. Here’s a quick overview:
- Keyless Entry Key Fob: This is the most common type, featuring a single button for unlocking and locking the car.
- Keyless Entry and Push-to-Start Key Fob: This version includes a button for starting the car and may have additional buttons for trunk release or other features.
Opening the Key Fob
Locate the seam on the key fob. This is usually a thin line running around the perimeter. Use your flat-head screwdriver to carefully pry open the seam. Start at one end and gently work your way around the fob. Be careful not to apply too much pressure, as you don’t want to damage the key fob.
Removing the Old Battery
Once the key fob is open, you’ll see the old battery. It’s typically held in place by a small spring or clip. Use your fingers or the small, non-metallic object to gently push the battery out of its housing.
Inserting the New Battery
Take the new CR2032 battery and align it correctly within the key fob housing. Ensure the positive (+) side of the battery faces the correct direction. You’ll usually find a small diagram or marking inside the key fob indicating the correct orientation.
Closing the Key Fob
Carefully snap the two halves of the key fob back together. Ensure they are securely aligned and closed. If the key fob doesn’t close easily, double-check that the battery is properly inserted and the key fob is aligned correctly.
Testing the Battery
Once the key fob is closed, test the new battery by pressing the unlock and lock buttons. The key fob should respond as usual. If it doesn’t, double-check the battery orientation and ensure the key fob is properly closed.
Additional Tips
- Battery Life: CR2032 batteries typically last for 1-2 years, depending on usage.
- Key Fob Malfunctions: If your key fob still doesn’t work after replacing the battery, there may be a more serious issue with the key fob itself. Consult your local Audi dealer or a qualified automotive locksmith for further assistance.
- Storing Your Key Fob: When not in use, try to store your key fob in a cool, dry place to prolong the battery life.
Beyond Battery Replacement
While changing the battery is a common fix, other issues can cause key fob problems. Here are some additional troubleshooting steps:
- Check the Key Fob’s Range: If the key fob works intermittently, it might be a range issue. Try moving closer to your car and testing the key fob again.
- Clean the Key Fob: Dirt and grime can build up on the key fob’s buttons, affecting its functionality. Use a soft cloth and mild soap to clean the key fob, ensuring it’s completely dry before using it.
- Check the Car’s Battery: A weak car battery can sometimes interfere with the key fob’s signal. Make sure your car’s battery is in good condition.
