Recognizing a Dying Key Fob Battery in Your 2017 VW Passat

Before you rush to replace your key fob battery, it’s essential to confirm that it’s the actual culprit. Here are some telltale signs that your 2017 VW Passat key fob battery might be nearing its end:

• Decreased Remote Range: Do you find yourself standing closer to your Passat than usual to lock or unlock the doors? A weak battery often results in a significantly reduced remote control range.
• Intermittent Key Fob Functionality: Is your key fob working sporadically or only responding after multiple attempts? This inconsistency is another common indicator of a failing battery.
• Dashboard Warning Light: Some VW Passats might display a warning message on the dashboard, such as “Key Fob Battery Low,” signaling the need for a replacement.
• Difficulty Starting the Engine: In certain situations, a critically low key fob battery might interfere with the vehicle’s immobilizer system, making it challenging to start the engine.

Don’t fret if you’ve determined that your key fob battery needs replacing. It’s a simple process that you can handle with a few basic tools. Here’s a step-by-step guide to get you started:

1. Gather Your Supplies: You’ll need a new CR2032 battery, a small flat-head screwdriver or a plastic pry tool, and your 2017 VW Passat key fob.

3. Open the Battery Compartment: Carefully insert the flat-head screwdriver or pry tool into the slot and gently pry open the battery compartment cover.

4. Remove the Old Battery: Gently remove the old CR2032 battery from the compartment. Note the battery’s orientation for proper replacement.
