Types of Batteries Used in Volkswagen Key Fobs
Volkswagen key fobs use different types of batteries depending on the model and the year of the vehicle. Here are the most common types of batteries used:
- CR2032: This is the most common type of battery used in Volkswagen key fobs. It is a lithium coin cell battery with a diameter of 20mm and a thickness of 3.2mm.

Battery Lifespan and Replacement
The lifespan of a Volkswagen key fob battery can vary depending on factors such as usage frequency and the type of battery used. Generally, you can expect a lithium coin cell battery like the CR2032 to last anywhere between one to three years. However, factors such as extreme temperatures or prolonged exposure to moisture can shorten the battery’s lifespan.
When the battery in your Volkswagen key fob starts to run low, you may notice a decrease in the remote’s range or that it takes multiple attempts to unlock or lock your vehicle. It’s a good idea to replace the battery as soon as you notice these signs to prevent any inconvenience or potential lockouts.
Replacing the battery in a Volkswagen key fob is a relatively simple process. Here’s a step-by-step guide:
- Locate the battery compartment on your key fob. It is usually located on the backside and can be opened with a small screwdriver or coin.
- Remove the old battery from the compartment. Pay attention to the battery orientation (positive side up) to ensure proper installation.
- Insert the new battery into the compartment with the correct orientation.
- Close the battery compartment securely.
It’s important to handle the battery with care and avoid touching the contacts with your fingers to prevent any corrosion or interference with its performance. If you’re unsure about the replacement process, it’s recommended to consult your vehicle’s owner’s manual or seek assistance from a professional.
Other Tips and Considerations
Here are some additional tips and considerations regarding Volkswagen key fob batteries:
