If your Subaru key fob won’t unlock your car, you’re not alone. This is a common issue that can be caused by a variety of factors, from a dead battery to a faulty key fob. Let’s explore some common reasons why your Subaru key fob might not be working and provide effective solutions to get you back on the road.
Why Your Subaru Key Fob Won’t Unlock
There are several reasons why your Subaru key fob might not unlock your car. Identifying the root cause is crucial for finding the right solution.
Dead Key Fob Battery
One of the most common culprits is a dead key fob battery. If your key fob’s battery is depleted, it won’t have enough power to transmit the unlock signal to your car. This is often accompanied by a dim or non-existent LED light on the fob when you press a button.
Key Fob Programming Issues
Sometimes, the issue isn’t the battery, but the programming of the key fob itself. The connection between the key fob and your car’s receiver can be disrupted, leading to unlocking problems. This can happen after a battery replacement or other electrical work on the car.
Keyless Entry System Malfunction
The problem may not be with your key fob at all, but rather with the car’s keyless entry system. A faulty receiver or wiring issue within the car can prevent the fob’s signal from being received.
Signal Interference
In some cases, external signal interference can prevent your key fob from working correctly. Radio waves from other devices, such as cell phones or security systems, can sometimes disrupt the communication between the fob and the car.
Troubleshooting Your Subaru Key Fob
Here are some steps to troubleshoot your Subaru key fob issue:
- Check the key fob battery: Try replacing the battery with a new one. This is often the simplest and most effective solution.
- Try the spare key fob: If you have a spare key fob, see if it works. If the spare fob unlocks the car, you know the problem lies with the original fob and not the car’s system.
- Try unlocking manually: Use the physical key hidden inside the key fob to unlock the driver’s side door. This can bypass the keyless entry system and help you determine if the issue is with the fob or the car’s receiver. 2015 subaru fob mechanical key wont unlock
- Check for signal interference: Move away from any potential sources of interference, such as electronic devices or large metal objects. Try unlocking the car again in a different location.
How do I know if my key fob needs reprogramming?
If replacing the battery doesn’t solve the problem and your spare fob isn’t working either, it’s possible your key fob needs reprogramming.
