How to Troubleshoot: Volkswagen Unlock Button Not Working

Your Volkswagen’s unlock button is one of the most important features, allowing you to quickly and easily get into your car. However, if the button stops working, it can be a major inconvenience. There are a few possible causes for this issue, and you can usually troubleshoot the problem yourself.

Possible Causes

The most common cause of a Volkswagen unlock button not working is a faulty switch. The switch is located inside the door panel, and it can become damaged over time due to wear and tear. Another possible cause is a problem with the wiring harness. The harness connects the switch to the car’s computer, and if it is damaged, it can prevent the switch from working properly. Finally, a failing battery can also cause the unlock button to stop working.

Troubleshooting Steps

To troubleshoot the problem, you will need to first identify the cause. Here are a few steps to help you do this:

1. Check the switch. The first step is to check the switch itself. To do this, open the door panel and locate the switch. Press the button and see if it makes any noise or feels different than normal. If the switch is not working properly, you will need to replace it.
2. Check the wiring harness. If the switch is working properly, the next step is to check the wiring harness. To do this, use a voltmeter to test the voltage at the switch. If there is no voltage, the wiring harness is likely damaged and will need to be replaced.
3. Check the battery. If the switch and wiring harness are working properly, the final step is to check the battery. To do this, use a voltmeter to test the battery’s voltage. If the battery is not providing enough power, it will need to be replaced.

How to Replace the Unlock Button

If the unlock button is faulty, you will need to replace it. Here are the steps involved:

1. Remove the door panel. To remove the door panel, you will need to first remove the door trim. Once the trim is removed, you will see the screws that hold the door panel in place. Remove these screws and carefully pry the door panel away from the door.
2. Locate the switch. The unlock button switch is located on the inside of the door panel. It is a small, rectangular switch with two terminals.
3. Disconnect the switch. To disconnect the switch, you will need to remove the two screws that hold it in place. Once the screws are removed, the switch can be lifted out of the door panel.
4. Install the new switch. To install the new switch, simply reverse the steps above. Make sure to connect the switch to the correct terminals.
5. Reattach the door panel. Once the new switch is installed, you can reattach the door panel. To do this, simply reverse the steps above.
