Why Your Subaru Key Fob Is Not Working: Common Reasons

3 minute read

Experiencing a Subaru key fob not working issue can be more than a minor inconvenience for Subaru owners. The key fob is an essential tool for modern vehicles, providing easy access and security. When it fails to function, it can disrupt your daily routine and raise concerns about vehicle accessibility and safety.

Haynes Manuals: Your Guide to Resolving Subaru Key Issues

Turning to Haynes Manuals can be your best action when confronted with a Subaru key fob not working. Our extensive range of Automotive Manuals, including Subaru Repair Manuals, provides detailed and user-friendly instructions for diagnosing and fixing key fob issues. Whether you're a hands-on car owner or someone seeking knowledge before consulting a professional, our guides cover a broad spectrum of problems and solutions tailored specifically to Subaru vehicles.

Dead or Weak Battery

A common reason for your Subaru key fob malfunctioning is a dead or weak battery. Key fobs rely on a small battery to transmit signals to your vehicle. Over time, these batteries can lose power, causing the key fob to become unresponsive. Replacing the battery is a simple and effective solution. It's advisable to check the battery's condition periodically and replace it when necessary to ensure your key fob functions correctly. This straightforward maintenance step can save you from the inconvenience of a non-working key fob.

Key Fob Damage

Physical damage to your key fob can render it inoperative. Accidental drops, exposure to moisture, or other forms of impact can result in internal damage that disrupts the key fob's ability to communicate with your Subaru. In such cases, replacing the damaged key fob is usually the most viable solution. Protecting your key fob from physical damage is important to maintain its functionality.

Signal Interference

Signal interference is another culprit behind a malfunctioning key fob. Electronic devices and physical structures like buildings can interfere with the key fob's signal transmission. When faced with signal issues, try using the key fob from different angles or locations to see if the problem persists. Sometimes, a change in positioning or environment can help overcome signal interference and restore normal key fob operation.

Programming Issues

Programming problems can disrupt the synchronization between your key fob and your Subaru's keyless entry system. This may occur after a battery replacement or due to a malfunction in the vehicle's programming. You must typically re-sync the key fob with your car to address this issue. This straightforward process can often resolve programming-related key fob problems.

Faulty Keyless Entry System

Sometimes, the key fob's malfunction may be attributed to a faulty keyless entry system within your Subaru. This is a more complex issue that may require professional diagnosis and repair. When all other solutions fail to restore the key fob's functionality, it's essential to have the keyless entry system thoroughly examined and repaired by a qualified technician.
