Volkswagen Polo Key Fob Not Working

Not being able to use your key fob to lock, unlock, or start your vehicle can be a major inconvenience. This guide will help you troubleshoot the issue and potentially resolve it so that you can get back to using your key fob as intended.

The steps outlined in this guide are designed to help you quickly and easily diagnose the problem. However, if you are unable to resolve the issue on your own, it is always best to have your vehicle serviced by a qualified Volkswagen technician.

Why Volkswagen Polo Key Fob Not Working

Dead Battery

The most common reason for a Volkswagen Polo key fob not working is a dead battery. The key fob battery is a small, round, coin-shaped battery that powers the key fob’s electronic components. When the battery dies, the key fob will no longer be able to send a signal to the car, and the car will not be able to be unlocked or started.

Low Battery

A low battery can also cause problems with a Volkswagen Polo key fob. When the battery is low, the key fob may not be able to send a strong enough signal to the car, and the car may not be able to be unlocked or started.

Faulty Key Fob

In some cases, a Volkswagen Polo key fob may stop working due to a fault with the key fob itself. This could be caused by a damaged circuit board, a broken antenna, or a faulty chip.

Interference

In some cases, a Volkswagen Polo key fob may stop working due to interference from other electronic devices. This could be caused by a nearby cell phone, a radio, or a microwave oven.

Damaged Key Fob

A Volkswagen Polo key fob may also stop working if it is damaged. This could be caused by dropping the key fob, getting it wet, or exposing it to extreme heat or cold.

Troubleshooting a Faulty Key Fob

If you’re experiencing any of the symptoms listed above, you can try troubleshooting the key fob yourself. Here are a few things you can check:

Check the battery. The most common cause of a key fob not working is a low battery. To check the battery, open the key fob and look for a small, round battery. If the battery is corroded or damaged, replace it with a new one.
Clean the key fob. If the battery is good, the next thing you can try is cleaning the key fob. Sometimes, dirt or debris can get in the way of the key fob’s sensors, preventing it from working properly. To clean the key fob, use a soft cloth to wipe it down.
Reprogram the key fob. If cleaning the key fob doesn’t work, you may need to reprogram it. To reprogram the key fob, follow the instructions in your Volkswagen Polo owner’s manual.
