Experiencing issues with your Subaru Key Fob Remote Start? As auto repair experts at keyfobx.com, we understand the frustration. If your Subaru’s remote start system suddenly stops working, even if it functioned perfectly before, several factors could be at play. Let’s diagnose and troubleshoot common problems to get your remote start back in action.
First, ensure all preconditions for remote start are met. Are all doors, the hatch, and the hood completely closed and securely locked? Is your Subaru confirmed to be in “Park”? Remote start systems are designed with safety in mind and will not engage if any of these conditions are not satisfied. A seemingly minor sensor issue related to these components could prevent the remote start command from being processed.
When you attempt to remote start, observe the feedback from your vehicle. You mentioned “the lights come on”—how many times do they flash? Also, you hear the horn—how many times does it sound? These signals are crucial for diagnosing the problem.
Are you using the correct key fob sequence? Refer to your owner’s manual, but generally, it involves pressing the lock button, followed by a specific sequence to initiate remote start.
Are you receiving proper feedback from your key fob and vehicle at each step of this process? Incorrect feedback, or no feedback at all, points to different potential issues.
Your Subaru manual indicates that new standalone transmitters can be registered to your vehicle, assuming the remote start system itself is functioning correctly. This might be relevant if you suspect a key fob malfunction.
If these basic troubleshooting steps don’t resolve the issue, a simple battery reset might help. Before considering purchasing a new remote, try disconnecting your Subaru’s battery. Discharge any residual electrical charge in the system by pressing the brake pedal for a few seconds. Then, reconnect the battery and manually start your vehicle once with the key. Afterward, attempt to use the remote start again.
While a battery reset may not always be the solution, especially if the remote start hasn’t been used recently and the vehicle has been started manually multiple times since the issue arose, it’s a worthwhile step to try. If none of these steps work, further professional diagnosis may be required to pinpoint sensor faults or deeper system issues.
