Do you have issues opening your Audi doors with the remote keyless entry? If you own an Audi, then you are aware that one of the most useful features of the car is the keyless entry system. All you need is a push of a button, and you can lock or unlock your doors even if the key fob is still in your pocket. But what happens when this system suddenly stops working?
The keyless entry system, also referred to as Advanced Key, is used in Audi cars. It consists of sensors and the key fob. Each of these components is very important, and if they fail, you will be locked out of your car or unable to start your Audi. Here are the steps to follow if your Audi keyless entry system has developed some issues and how to get it repaired by a professional.
Causes and Solution For Audi Keyless Entry Failures
- Replace the Key Fob Battery: The first thing you should do is to check whether the battery of the key fob is low or dead and replace it if possible. This is an easy and inexpensive fix that often resolves the problem. It is very important that you use the correct battery type for your Audi model. After installing the new keyless entry system, try to use it to ensure that it is functioning effectively.
- Check Signal Interference: If your keyless entry is not working in some areas, it is advised that you move away from systems such as electronic gates, security systems, or any other device that may be interfering with the keyless entry. When you are distant from the interference, check if the system has resumed its function. If it works, then interference was probably the problem.
- Use Secondary Key Fob: If you have another keyless entry fob, try to use it to see if the problem is with the first fob or the car’s system. As soon as you notice that the backup key fob is responding well, you should check the condition of the primary key fob and fix whatever issues it has, whether it needs a new battery or replacement.
- Reset the System: In some cases, keyless entry issues can be solved by resetting the system. Attempt to lock and unlock the car using the buttons on the key fob. If the problem continues, the car battery should be turned off for a few minutes and then connected again to possibly reboot the system.
- Check Car Battery: If your Audi does not start or if it experiences some electrical issues, it is wise to check the battery of the car. The keyless entry system can be affected by a weak or a dying battery. In case the battery is dead or its capacity is low, try replacing it and see if your keyless entry will work.
- Clean Door Handle Sensors: Sometimes, the sensors in the door handles get dirty, covered with grime, or iced, and, therefore, cannot pick up the signal from the key fob. It is advisable to clean the handles with a cloth to remove any dirt that may be on the surface. During cold weather, one needs to make sure that there is no ice accumulation on the sensors.
- Contact a Mechanic: If you have applied some of the above methods and you notice that your keyless entry system is still not working, it is advisable to take your Audi car to a professional Audi mechanic. They can perform tests to determine whether it is an electrical issue or a sensor-related problem.
