VW Tiguan Key Fob Not Working After Battery Change

If your VW Tiguan key fob isn’t working after a battery change, you’re not alone. This is a surprisingly common issue, but thankfully, there are usually simple solutions. This article will guide you through the most common causes and solutions, helping you get back on the road quickly.

Common Reasons for VW Tiguan Key Fob Malfunction After Battery Change

Several factors can cause your VW Tiguan key fob to stop working after replacing the battery. Here’s a breakdown of the most common culprits:

• Incorrect Battery Installation: It might seem obvious, but double-check that the new battery is correctly oriented in the key fob. A reversed battery won’t provide power.
• Dead New Battery: Sometimes, new batteries can be faulty or have a short shelf life. Test the new battery with a multimeter to ensure it has the correct voltage.
• Key Fob Needs Resynchronization: After a battery change, the key fob sometimes needs to be resynchronized with your Tiguan’s immobilizer system.
• Damaged Key Fob: While less common, dropping the key fob during the battery change process could damage internal components.

How to Fix a VW Tiguan Key Fob Not Working After Battery Change

Here are some steps to troubleshoot and fix a non-responsive key fob:

1. Verify Battery Installation: Open the key fob and ensure the new battery is installed correctly, matching the positive (+) and negative (-) terminals. If you’re unsure, refer to your owner’s manual or search online for instructions specific to your Tiguan model year.
