Owning a 2018 VW Tiguan comes with many perks, but discovering a dead key fob can quickly turn into a frustrating experience. If you find yourself stranded with a lifeless key fob, don’t panic! This guide provides practical solutions to help you get back on the road and understand the ins and outs of your VW Tiguan’s keyless entry system.
Common Causes of a Dead Key Fob
Before delving into the solutions, let’s understand the usual suspects behind a dead key fob:
- Depleted Battery: The most common culprit is a drained key fob battery. Over time, the battery loses its charge, rendering the key fob useless.
- Key Fob Programming Issues: Occasionally, the key fob might lose its programming, preventing it from communicating with your Tiguan.
- Internal Key Fob Damage: Physical damage from drops, water exposure, or wear and tear can also lead to a malfunctioning key fob.
How to Start Your 2018 VW Tiguan with a Dead Key Fob
1. Check and Replace the Key Fob Battery
This is the first and easiest solution to try. Most 2018 VW Tiguan key fobs use a CR2032 battery. You can usually find this battery type at most convenience stores or auto parts shops.
To replace the battery:
- Locate the small slot on the back of your key fob.
- Use a flat-head screwdriver or a coin to pry open the key fob casing.
- Carefully remove the old battery and replace it with the new CR2032 battery, ensuring the positive (+) side faces up.
- Snap the key fob casing back together.
After replacing the battery, try starting your car. If it doesn’t work, move on to the next solution.
“Many people overlook the simplest solution – a dead battery. Always check and replace the battery first before assuming a more complex issue,” advises John Miller, Senior Automotive Electrician at Miller’s Auto Solutions.
2. Use the Mechanical Key
Your 2018 VW Tiguan key fob comes with a hidden mechanical key. You can use this key to unlock your car door manually and start the ignition.
To access the mechanical key:
- Locate the small release button on your key fob.
- Press the button to release the mechanical key.
Use the key to unlock the driver’s side door and insert it into the ignition cylinder to start your car.
3. Contact a Locksmith or Dealership
If replacing the battery and using the mechanical key doesn’t work, you might be dealing with a more complex issue, such as Key Fob Programming problems or internal damage. In such cases, it’s best to contact a qualified locksmith or your VW dealership for assistance. They have the expertise and specialized tools to diagnose and resolve the issue effectively.
Preventing Future Dead Key Fob Situations
- Regular Battery Replacement: Consider replacing your key fob battery every 2-3 years as a preventative measure.
- Handle with Care: Avoid dropping your key fob or exposing it to extreme temperatures or water.
- Keep a Spare Key: Always have a spare key fob readily available in case of emergencies.
Conclusion
A dead key fob can be an inconvenience, but understanding the potential causes and solutions can help you overcome this challenge with minimal hassle. Remember to start with the simplest solution – checking the battery – and if necessary, don’t hesitate to seek professional assistance from a locksmith or dealership. By following these tips, you can get back on the road quickly and prevent similar situations from occurring in the future.
