Why Replace the Key Fob Battery?
The key fob battery is responsible for transmitting signals to your Jetta, allowing you to lock and unlock the doors remotely. If the battery is weak or dead, you may face difficulties in accessing your car. Therefore, it is crucial to replace the key fob battery promptly to avoid any inconvenience or potential lockout situations.
Determining the Battery Type
Before replacing the key fob battery, you need to identify the appropriate battery type. The 2021 Jetta key fob typically uses a CR2032 battery, but it is always advisable to consult your owner’s manual or contact the dealership to confirm the correct battery type for your specific model.
Gathering the Required Tools
Once you have confirmed the battery type, gather the necessary tools for the replacement process. You will need a small flathead screwdriver, a replacement CR2032 battery, and a clean cloth to prevent any damage to the key fob.
Replacing the Key Fob Battery
Begin by locating the small notch on the side of the key fob. Insert the flathead screwdriver into the notch and gently twist it to separate the key fob’s two halves. Be careful not to apply excessive force to prevent any damage.
Removing the Old Battery
Once the key fob is open, you will find the old battery. Carefully remove the old battery by gently prying it out using the flathead screwdriver. Be cautious not to damage any other components within the key fob during this process.
Inserting the New Battery
Take the replacement CR2032 battery and insert it into the designated slot within the key fob. Ensure that the positive side of the battery is facing upwards. Press the battery firmly to secure it in place.
Reassembling the Key Fob
Now that the new battery is in place, it’s time to reassemble the key fob. Align the two halves of the key fob and gently press them together until they snap back into place. Take care not to misalign any buttons or damage the key fob during this step.
Testing the Key Fob
Once the key fob is reassembled, test it by pressing the lock and unlock buttons. If the buttons respond as expected, congratulations! You have successfully replaced the key fob battery. If not, double-check the battery installation and reassemble the key fob again.
