Experiencing issues with your 1999 Subaru Forester Key Fob can be a frustrating inconvenience. If your remote isn’t unlocking your doors or setting off the alarm as expected, don’t worry, you’re not alone. Many owners of this classic SUV encounter similar problems. Before you rush to a mechanic or consider expensive replacements, there are several straightforward troubleshooting steps you can take yourself. This guide will walk you through some common culprits and easy fixes to get your 1999 Subaru Forester key fob working again.
Common Issues and Quick Fixes
Often, key fob problems stem from simple oversights or easily resolvable issues. Let’s explore some of the first things you should check to diagnose and potentially fix your malfunctioning key fob.
Check the Fuses
A blown fuse is a surprisingly common cause of key fob malfunctions. Your Subaru Forester’s electrical system relies on fuses to protect various circuits, and it’s possible that a fuse related to the remote keyless entry system has failed.
How to check your fuses:
- Locate the fuse box: Typically, fuse boxes are located in the engine compartment and under the dashboard. Consult your owner’s manual for the exact locations in your 1999 Subaru Forester.
- Identify the correct fuse: Refer to the fuse box diagram (usually printed on the fuse box cover or in your owner’s manual) to find the fuse associated with the keyless entry system, remote door locks, or security system.
- Inspect the fuse: Carefully remove the fuse using a fuse puller (often found in the fuse box itself). Hold the fuse up to the light and look for a broken wire inside the fuse. If the wire is broken, the fuse is blown.
- Replace the fuse: If you find a blown fuse, replace it with a new fuse of the same amperage rating. You can usually purchase replacement fuses at any auto parts store.
Even if you’ve checked fuses before, it’s worth double-checking specifically for the key fob system. A simple fuse replacement might be all it takes to restore your key fob’s functionality.
Replace the Key Fob Battery
The most frequent cause of a non-working key fob is a dead or weak battery. Key fob batteries, like any battery, have a limited lifespan and will eventually need replacement. This is a simple and inexpensive fix that you can easily do at home.
How to replace your key fob battery:
- Identify your key fob battery type: Open your key fob casing. The battery type is usually printed directly on the battery itself. Common types include CR2032, CR1620, or CR2025.
- Open the key fob: Depending on your key fob design, you may need a small Phillips head screwdriver or a thin flathead screwdriver to carefully pry open the casing. Look for small screws or a notch to insert a screwdriver.
- Remove the old battery: Gently remove the old battery. Take note of the battery orientation (+ and – sides).
- Install the new battery: Insert the new battery, ensuring it’s in the correct orientation.
- Reassemble the key fob: Carefully snap the key fob casing back together and replace any screws.
After replacing the battery, test your key fob to see if it now works. This is often the quickest and easiest solution to key fob problems.
Inspect the Security System Control Module
If fuses and the battery are not the issue, the problem might be related to the security system control module. This module is responsible for receiving the signal from your key fob and activating the door locks and alarm system.
How to inspect the control module:
- Locate the control module: The location of the security system control module can vary, but it’s often found under the dashboard, near the steering column, or behind the glove compartment. Searching online forums specific to the 1999 Subaru Forester can provide more precise location information. Look for a module box that may have a label indicating it’s the security or alarm system module.
- Check for loose connections: Once you locate the module, visually inspect it for any loose or disconnected wires. Gently wiggle the connectors to ensure they are securely plugged in.
- Look for damage: Examine the module and wiring for any signs of physical damage, such as cuts, frayed wires, or corrosion.
In the original forum post, the user mentioned finding their module under the dash and discovering cut siren wires. While cut siren wires might affect the alarm sound, it’s also possible other wiring issues could impact the key fob’s ability to communicate with the system. If you notice any obvious wiring problems, attempt to repair them if you are comfortable doing so, or consult a professional.
Locate and Test the Programming Button
Many older Subaru models, including the 1999 Forester, have a programming button that can be used to program new key fobs or reset the system. This button is often hidden and can be easily overlooked.
How to find and test the programming button:
- Search for the button: The programming button is typically a small, recessed button, often white or black plastic. It’s commonly located under the dashboard on the driver’s side, near the hood release lever. It might be mounted on a bracket or tucked away. Refer to your owner’s manual or online forums for specific locations for the 1999 Forester. The original forum post mentions finding a small white plastic button under the dash near the engine latch pull.
- Test the button: Once you locate the button, try pressing it. Sometimes, simply pressing this button can reset the system or put it into programming mode (though specific programming procedures vary). Refer to your owner’s manual or search online for “1999 Subaru Forester key fob programming” to find specific instructions that may involve using this button in combination with key and door lock actions.
Finding and testing this button is crucial because it’s often a key step in programming new key fobs if battery and fuse checks don’t resolve the issue. It’s also possible the button itself is stuck or malfunctioning, which could prevent proper key fob operation.
Still Having Trouble?
If you’ve tried these troubleshooting steps and your 1999 Subaru Forester key fob is still not working, it might be time to seek further assistance. Consider these next steps:
- Consult your owner’s manual: Your owner’s manual is a valuable resource that may contain specific troubleshooting steps or programming instructions for your key fob and security system.
- Search online forums: Online Subaru Forester forums are a wealth of information. Other owners may have experienced similar issues and shared solutions. Search for threads related to “1999 Subaru Forester key fob problems” or “key fob programming.”
- Contact a professional: If you’re not comfortable working on your car’s electrical system or if the problem persists, take your Subaru Forester to a qualified mechanic or a dealership service center. They have specialized tools and expertise to diagnose and repair more complex key fob and security system issues.
Troubleshooting your 1999 Subaru Forester key fob can often be a process of elimination. By starting with these simple checks and systematically investigating potential causes, you increase your chances of resolving the problem yourself and avoiding unnecessary expenses. Remember to be patient and persistent, and you’ll likely get your key fob working again.
