Identifying the Correct Battery for Your 2016 VW Jetta Key Fob
Using the correct battery is essential for the proper function of your key fob. The 2016 VW Jetta typically uses a CR2032 3V lithium battery. This battery is readily available at most electronics stores, pharmacies, and online retailers. While it might be tempting to use a similar-looking battery, it’s crucial to stick with the CR2032 to ensure compatibility and avoid potential damage to your key fob.
What happens if you use the wrong battery? “Using an incorrect battery can lead to voltage inconsistencies which could damage the key fob’s circuitry,” warns automotive electronics expert, Dr. Emily Carter, PhD. She adds, “Always double-check the battery type before installation.”
