Why Volkswagen Keyless Entry Not Working

Dead or Weak Battery

The most common reason for a keyless entry system not working is a dead or weak battery in the key fob. If the battery is too low, the key fob will not be able to send a signal to the car, and the keyless entry system will not work. To check the battery, look for a small, round, flat battery in the back of the key fob. If the battery is bulging or corroded, it needs to be replaced. You can usually find replacement batteries at most hardware stores or online.

Improper Installation

If the keyless entry system was not installed correctly, it may not work properly. Make sure that the system was installed by a qualified technician. If you are not sure whether the system was installed correctly, have a qualified technician take a look at it.

Damaged Key Fob

The key fob itself can be damaged, which can prevent it from working properly. If the key fob is dropped, it can damage the internal components. If the key fob is exposed to water or other liquids, it can also damage the internal components. If you think the key fob may be damaged, you can try replacing it. You can usually find replacement key fobs at most Volkswagen dealerships or online.

Interference

Other electronic devices, such as cell phones, can interfere with the keyless entry system. If you are having trouble with your keyless entry system, try turning off your cell phone and see if that fixes the problem. You can also try moving your car away from other electronic devices.

Software Problems

In some cases, the keyless entry system may not work properly due to a software problem. If you are having trouble with your keyless entry system, you can try updating the software. You can usually find software updates at your Volkswagen dealership or online.

What to Do If Your Volkswagen Keyless Entry Isn’t Working

Your Volkswagen keyless entry system is a convenient way to get into your car without having to take your keys out of your pocket. But what happens when it stops working? Here are some things you can do to troubleshoot the problem:

1. Check the battery in your key fob. This is the most common cause of keyless entry problems. If the battery is low, your key fob may not be able to communicate with your car. To check the battery, look for a small door on the back of your key fob. Inside, you’ll find a small battery. If the battery is corroded or looks old, replace it with a new one.
2. Try reprogramming your key fob. If your key fob is still not working after you replace the battery, you may need to reprogram it. To do this, follow the instructions in your car’s owner’s manual.
3. Check the antenna in your car. The antenna is located in the rear window of your car. If the antenna is damaged, it may not be able to communicate with your key fob. To check the antenna, look for a small black box on the inside of your rear window. If the box is damaged, you’ll need to have it replaced.
4. Take your car to a dealership. If you’ve tried all of the above steps and your keyless entry system is still not working, you may need to take your car to a dealership. The dealership can diagnose the problem and make the necessary repairs.

Preventative Measures You Can Take to Avoid Keyless Entry Problems

There are a few things you can do to help prevent keyless entry problems:

Keep your key fob away from water and other liquids. Water and other liquids can damage the battery in your key fob, which can lead to keyless entry problems.
Don’t drop your key fob. Dropping your key fob can damage the internal components, which can also lead to keyless entry problems.
Don’t expose your key fob to extreme heat or cold. Extreme heat and cold can damage the battery in your key fob, which can lead to keyless entry problems.
Keep your key fob in a safe place. If you lose your key fob, someone else could use it to gain access to your car. To avoid this, keep your key fob in a safe place, such as your purse or pocket.

By following these tips, you can help prevent keyless entry problems and keep your car safe.
