Common Causes of Subaru Key Fob Problems
Several factors can contribute to a malfunctioning Subaru key fob. Understanding these causes can help you diagnose the problem more effectively.
Dead Battery
As mentioned earlier, a dead battery is the most common reason for key fob failure. Over time, the battery’s power depletes, rendering the fob useless. A quick battery replacement usually solves the problem.
Key Fob Programming Issues
Sometimes, the key fob might lose its programming, preventing it from communicating with your Subaru’s system. This can happen due to various reasons, including electrical interference or a weak key fob battery. Reprogramming the key fob can restore its functionality.

Faulty Key Fob
Internal damage to the key fob, such as a broken circuit or damaged components, can also cause it to stop working. Physical damage from dropping the fob or exposure to moisture can contribute to this issue. In such cases, you might need a key fob replacement.
Receiver Issues
The receiver in your Subaru, responsible for receiving signals from the key fob, can also malfunction. If the receiver is faulty, it won’t be able to detect the key fob’s signal, preventing the car from unlocking or starting.
Keyless Entry System Malfunction
In some cases, the entire keyless entry system in your Subaru might be malfunctioning. This could be due to a blown fuse, wiring problems, or a faulty control module. Diagnosing and repairing this issue often requires professional expertise.
