Experiencing trouble programming your 2000 Subaru Key Fob? You’re not alone. Many Subaru owners encounter difficulties when trying to program or reprogram their key fobs, especially with older models like the 2000 Outback. This article delves into common issues, troubleshooting steps, and solutions to get your 2000 Subaru key fob working again.
One Subaru owner recently shared their experience attempting to program a spare, multi-colored button key fob to their newly acquired 2000 Outback. Initially, the car entered programming mode, indicated by a beep after turning the ignition off-on ten times. Following the presumed programming steps – pressing buttons on the fob – three beeps were heard, typically signaling success. However, neither the new nor the original key fob worked afterward, and the car wouldn’t re-enter programming mode. This situation, where the ECU seems “stuck” and unresponsive to key fob programming, is a frustrating problem for 2000 Subaru key fob users.
Several factors could contribute to programming failure with a 2000 Subaru key fob. It’s possible that:
- Incorrect Programming Procedure: Subaru key fob programming sequences can be specific to the model year. Minor deviations from the correct procedure for a 2000 Subaru key fob can lead to failure.
- Fob Compatibility: While some older Subaru fobs with gray buttons and newer colored button fobs might appear interchangeable, compatibility issues can arise. A fob previously programmed to another vehicle should be reprogrammable, but unforeseen conflicts can occur.
- ECU Glitch: Like any electronic control unit, a Subaru’s ECU can experience glitches. Sometimes, the system responsible for key fob recognition and programming might become temporarily unresponsive.
- Receiver Malfunction: In rare cases, the radio receiver in the Subaru, responsible for receiving signals from the 2000 Subaru key fob, could be malfunctioning.
Troubleshooting Steps for Your 2000 Subaru Key Fob:
- Verify Programming Procedure: Double-check the exact key fob programming steps for a 2000 Subaru Outback. Consult your owner’s manual or reliable online resources that specifically detail the process for your model year. Ensure every step is followed precisely.
- Battery Check: While less likely to cause complete programming failure, ensure the batteries in both your original and spare 2000 Subaru key fob are fresh and functioning correctly. Low battery voltage can sometimes lead to erratic behavior.
- Door Switch Check: The programming procedure often involves opening and closing the driver’s door. A faulty door switch might prevent the system from entering or completing the programming sequence.
- ECU Reset Attempt: Try a basic ECU reset. Disconnecting the negative battery terminal for about 15-20 minutes can sometimes clear temporary glitches and allow the system to reset. After reconnecting the battery, retry the programming procedure for your 2000 Subaru key fob.
- Professional Diagnostic Scan: If basic troubleshooting fails, a professional diagnostic scan at a Subaru dealership or a qualified automotive repair shop is recommended. They have specialized tools to communicate with the Subaru’s ECU, diagnose potential issues within the keyless entry system, and potentially reprogram the 2000 Subaru key fob using professional equipment.
Encountering issues with your 2000 Subaru key fob can be inconvenient. By systematically troubleshooting and understanding potential causes, you can increase your chances of resolving the problem and regaining remote access to your Subaru Outback. If DIY attempts are unsuccessful, professional help is readily available to diagnose and fix more complex issues within your Subaru’s keyless entry system.
