Experiencing issues with your Subaru Crosstrek key fob can be frustrating, especially when it suddenly stops working. Imagine returning to your car after a pleasant trip, only to find your key fob refusing to unlock the doors remotely. You’re not alone if you’ve encountered this problem. Many Subaru Crosstrek owners have reported similar experiences where their key fob becomes unresponsive, even after replacing the battery. Let’s explore the common reasons behind a malfunctioning key fob and what steps you can take to resolve it.
One of the first and most common culprits for a non-working key fob is indeed a dead battery. While this might seem obvious, it’s often the simplest fix. If your key fob only works when held directly against the door lock, a depleted battery is highly likely. However, as one Subaru owner discovered after a trip, even a brand new battery doesn’t always solve the problem. They replaced their key fob battery, and while it initially seemed to work, the issue returned shortly after. This indicates that the problem might extend beyond just a simple battery replacement.
If you’ve already replaced the battery and your Subaru Crosstrek key fob is still not working correctly, there could be other underlying issues. One potential problem is corrosion or debris buildup within the key fob itself. Moisture, dust, and everyday grime can accumulate over time, particularly on the plastic membrane and electronic components inside the fob. This buildup can interfere with the electrical contacts and hinder the key fob’s ability to transmit signals effectively. In the original case, a Subaru dealership technician found a “thin white crust” inside the malfunctioning fob, suggesting corrosion as a possible factor.
So, what can you do if a new battery doesn’t solve your Subaru Crosstrek key fob problem? One approach, particularly if you suspect corrosion or dirt, is to carefully clean the key fob’s internal components. Using an electrical contact cleaner, such as CRC electrical cleaner, might help remove any corrosive buildup or debris that’s preventing proper function. To do this, you would need to carefully disassemble the key fob, gently apply the cleaner to the contacts and membrane, and allow it to dry completely before reassembling. However, proceed with caution when disassembling your key fob, especially if you are not comfortable with small electronics. It’s also worth noting the cost factor: replacing a key fob can be expensive, potentially costing around $250, plus additional programming fees that could reach $200 at a dealership. This cost can make DIY cleaning a more attractive first step before considering a full replacement.
If cleaning the key fob doesn’t restore its functionality, or if you’re hesitant to attempt a DIY fix, seeking professional help is the next logical step. Your local Subaru dealership is equipped to diagnose key fob issues and offer solutions, which may include reprogramming the existing fob or replacing it entirely. While the parts and programming costs can be significant, a dealership can ensure the job is done correctly and that your new or reprogrammed key fob works seamlessly with your Subaru Crosstrek. They can also accurately determine if the problem lies with the key fob itself or potentially with the vehicle’s receiver system.
In conclusion, a Subaru Crosstrek key fob that’s not working can stem from various causes, ranging from a simple dead battery to internal corrosion or electronic malfunction. Troubleshooting steps include battery replacement and careful cleaning of internal components. However, if these DIY efforts fail, professional diagnosis and repair from a Subaru dealership are recommended to ensure proper resolution, despite the potential cost. Remember to weigh the cost of professional service against the potential risks and complexities of DIY repairs when dealing with your car’s key fob system.
