What to Do If Your Volkswagen Spare Key Isn’t Working

Your Volkswagen spare key is a valuable asset, but what happens if it stops working? Here are a few things you can do to troubleshoot the issue:

1. Check the battery. The most common reason for a spare key to stop working is a dead battery. To check the battery, open the key fob and look for a small, round battery. If the battery is corroded or has leaked, it will need to be replaced.
2. Clean the key fob. If the battery is good, the next step is to clean the key fob. Over time, dirt and grime can build up on the key fob, which can interfere with its ability to communicate with the car. To clean the key fob, use a soft cloth to wipe it down. You can also use a small amount of rubbing alcohol to clean the contacts.
3. Reprogram the key fob. If cleaning the key fob doesn’t work, you may need to reprogram it. To reprogram the key fob, you will need to use a Volkswagen diagnostic tool. You can find a Volkswagen diagnostic tool at most auto parts stores.
4. Replace the key fob. If you have tried all of the above steps and your spare key still isn’t working, you may need to replace it. You can purchase a new key fob from your local Volkswagen dealer.

Preventative Measures

You can take a few steps to help prevent your Volkswagen spare key from malfunctioning:

Keep the key fob clean. Dirt and grime can build up on the key fob and interfere with its ability to communicate with the car. To prevent this, make sure to clean the key fob regularly.
Don’t expose the key fob to extreme temperatures. Extreme temperatures can damage the battery in the key fob. Avoid leaving the key fob in direct sunlight or in extreme cold.
Don’t drop the key fob. Dropping the key fob can damage the internal components. Be careful not to drop the key fob.
