How to Change the Battery in VW Key Fob

• Open the VW key fob using a flathead screwdriver
• Remove the old battery, noting its orientation
• Insert a new CR2032 battery with the positive side facing up
• Reassemble the fob and test it to ensure it’s working properly

Why Does Your VW Key Fob Need a New Battery?

Your VW key fob contains a small battery that powers its remote functions, including locking/unlocking the doors, starting the car, and activating the alarm. Over time, the battery inside the key fob will naturally lose its charge, leading to weaker or no response from the fob. If your VW key fob buttons are unresponsive, the key fob light is dim, or the signal is weaker than usual, it’s likely time for a battery change.

Replacing the battery in your VW key fob will restore its functionality, saving you time and money, and you won’t have to visit a dealership.

Tools You’ll Need to Change the Battery in Your VW Key Fob

Before you begin replacing the battery, make sure you have the following tools:

• Flathead screwdriver: To open the key fob without damaging it.
• New CR2032 battery: This is the most common battery for VW key fobs.
• Small, soft cloth (optional): To wipe away any dirt or debris from the key fob.

These are all the tools you’ll need to complete the process.

Step-by-Step Guide to Changing the Battery in Your VW Key Fob

Changing the battery in your VW key fob is simple, and with the following instructions, you can get the job done quickly.

Step 1: Open the VW Key Fob

Start by locating the seam where the two halves of your key fob meet. Most VW key fobs have a small groove along the edge where you can pry them open. Use the flathead screwdriver to gently insert into the groove. Twist the screwdriver slightly to help separate the two halves.

Be careful not to damage the key fob’s casing as you open it. Some models may also feature a metal key that needs to be removed before opening the fob. Slide it out carefully and set it aside.

Once the fob is open, you should see the internal components, including the battery.

Step 2: Remove the Old Battery

The battery inside your VW key fob is typically a CR2032 coin cell battery. Carefully remove the old battery from its compartment. Take note of the battery’s orientation before removing it – this is crucial for inserting the new battery correctly.

The positive side of the battery (the side with the plus sign) should face up, and the negative side faces down toward the key fob’s internal components.

Step 3: Insert the New Battery

Now that the old battery is removed, take your new CR2032 battery and insert it into the compartment. Make sure the positive side of the battery is facing up, and gently press the battery into place.

It’s important to use the exact same type of battery to ensure proper functionality. Other battery types may not fit properly, or they could cause the key fob to malfunction.

Step 4: Reassemble the Key Fob

Once the new battery is securely in place, it’s time to close the key fob. Align the two halves of the fob and press them together until you hear a clicking sound, indicating that the key fob is properly sealed.

If your fob contains screws, use a small screwdriver to reattach them. Otherwise, the fob should snap together without the need for any screws.

Step 5: Test the Key Fob

With the key fob reassembled, test it to make sure it works properly. Stand close to your car and press the lock/unlock button to see if the fob responds. The lights on the fob should blink, and the car should lock/unlock.

If the fob doesn’t work immediately, double-check the battery’s orientation. If the battery is installed correctly, but the fob still isn’t working, try using another battery or check for debris inside the key fob.

Troubleshooting: What to Do if the Key Fob Still Doesn’t Work

If your VW key fob isn’t working after you’ve replaced the battery, don’t worry – there are a few things you can check.

1. Double-Check the Battery Orientation

The most common cause of a non-working key fob after a battery replacement is incorrect battery orientation. Make sure the positive side is facing up.

2. Check for Dirt or Debris

Sometimes, dirt or debris can get inside the key fob and interfere with the battery’s connection. Use a soft cloth to gently clean the inside of the key fob.

3. Test the New Battery

It’s possible that the new battery is faulty. Try replacing it with another CR2032 battery to rule out a defective part.

4. Reprogram the Key Fob

In some cases, the key fob may need to be reprogrammed after the battery replacement. If your fob still isn’t working, refer to your VW owner’s manual for instructions on how to reprogram the key fob, or visit a dealership for assistance.

Maintenance Tips for Your VW Key Fob

To keep your VW key fob in good working condition and extend its lifespan, follow these tips:

• Replace the battery every 1-2 years: Regular battery replacements will help keep your key fob functioning properly.
• Clean your key fob: Wipe your key fob regularly to remove dirt and grime, which can interfere with its functionality.
• Avoid moisture: Water and moisture can damage the internal components of your key fob, so keep it away from wet environments.
• Store the key fob properly: Avoid dropping or mishandling your key fob, as physical damage can cause it to malfunction.
