Picture this: you’re rushing to get to work, reach for your 2018 VW Tiguan key fob, and… nothing. Your car key is unresponsive, leaving you stranded. Before you panic and call for a tow, consider this: your key fob battery might just need replacing.
Replacing the battery in your 2018 VW Tiguan key fob is a simple process that can be done at home in a matter of minutes, saving you the time and expense of a trip to the dealership.
Identifying a Dying Key Fob Battery
Before you start digging around for a replacement battery, it’s a good idea to confirm that a low battery is actually the culprit. Here are a few telltale signs:
- Decreased Range: Are you finding yourself having to stand closer to your Tiguan to lock or unlock the doors? This could be an early indication of a weakening battery.
- Intermittent Functioning: Is your key fob working sporadically, requiring multiple button presses to get a response? This is another common sign of a dying battery.
- Warning Lights and Messages: Some VW Tiguans may display warning messages on the dashboard or sound an alarm if the key fob battery is low.
What You’ll Need for the Replacement
Fortunately, replacing your 2018 VW Tiguan key fob battery doesn’t require any special tools or technical expertise. Here’s what you’ll need:
- A New CR2032 Battery: This is the standard battery type for most 2018 VW Tiguan key fobs. You can find them at most hardware stores, auto parts stores, and online retailers.
- A Small Flathead Screwdriver: This will be used to pry open the key fob casing.
