Why Volkswagen Tiguan Keyless Entry Not Working

Reasons why Volkswagen Tiguan keyless entry not working

Dead battery. The most common reason for a keyless entry system not working is a dead battery in the key fob. To check the battery, remove the key fob from your key ring and look for a small, round, metallic button on the back. Press the button and see if a light comes on. If not, the battery is dead and needs to be replaced.
Faulty key fob. If the battery in the key fob is not the problem, the key fob itself may be faulty. To test the key fob, try using it to lock and unlock the doors of your car. If the key fob does not work, you will need to have it replaced.
Interference. Keyless entry systems can be affected by interference from other electronic devices, such as cell phones, radios, and microwaves. If you are having trouble with your keyless entry system, try moving your car away from any sources of interference.
Damaged key fob. If the key fob has been damaged, it may not be able to communicate with your car’s computer. To check for damage, look for any cracks or breaks in the key fob. If you find any damage, you will need to have the key fob repaired or replaced.
Software problem. In rare cases, a software problem can cause a keyless entry system to stop working. If you have tried all of the other solutions and your keyless entry system is still not working, you may need to have the software in your car’s computer updated.

How to Troubleshoot: Volkswagen Tiguan Keyless Entry Not Working

Your Volkswagen Tiguan’s keyless entry system is a convenient way to get into your car without having to dig your keys out of your pocket. However, if your keyless entry system isn’t working, it can be a major inconvenience.

There are a few things that could be causing your keyless entry system to malfunction. In this article, we’ll walk you through the steps to troubleshoot the problem and get your keyless entry system working again.

Step 1: Check the batteries in your key fob

The most common cause of a keyless entry system not working is a dead battery in the key fob. To check the batteries, remove the key fob from your keychain and look for a small, rectangular slot on the back. Insert a small, thin object (such as a paperclip) into the slot and pry open the back cover.

Once the back cover is open, you’ll see two small batteries. Check to make sure that the batteries are properly inserted and that they’re not corroded. If the batteries are corroded, replace them with new ones.

If the batteries are not the problem, continue to the next step.

Step 2: Test the key fob

Once you’ve checked the batteries in your key fob, it’s time to test the key fob itself. To do this, press the lock button on the key fob. If the lights on your car flash, the key fob is working properly. If the lights don’t flash, the key fob is not working properly and you’ll need to replace it.

Step 3: Check the antenna

The antenna on your Volkswagen Tiguan is responsible for sending and receiving signals from your key fob. If the antenna is damaged, it can prevent your keyless entry system from working properly.

To check the antenna, look for a small, metal strip on the outside of your car. This is the antenna. If the antenna is damaged, you’ll need to have it repaired or replaced.

Step 4: Reset the keyless entry system

If you’ve checked the batteries in your key fob, tested the key fob, and checked the antenna, and your keyless entry system still isn’t working, you may need to reset the system.

To reset the keyless entry system, follow these steps:

1. Turn off your car and remove the key from the ignition.
2. Press and hold the lock button on your key fob for five seconds.
3. Turn the key to the On position and back to the Off position.
4. Press and hold the lock button on your key fob again for five seconds.

Your keyless entry system should now be reset.

Step 5: Take your car to a dealership

If you’ve tried all of the steps above and your keyless entry system still isn’t working, you’ll need to take your car to a dealership. The dealership will be able to diagnose the problem and repair it.

Conclusion

Your Volkswagen Tiguan’s keyless entry system is a convenient feature, but it can be a nuisance when it’s not working properly. By following the steps in this article, you can troubleshoot the problem and get your keyless entry system working again.
