1. Troubleshooting:
* Identify the exact problem: Is it just sticky when turning, or does it sometimes fail to turn at all? Does it feel rough, or is there a clicking sound? This helps determine the severity and potential causes.
* Check the key: Make sure your key isn't damaged or worn. A slightly bent or worn key can exacerbate a sticky switch. Try a spare key if you have one.
* Check the steering wheel lock: Ensure the steering wheel isn't locked. Try gently jiggling the wheel while attempting to turn the key.
2. Simple Solutions (Try these FIRST):
* Penetrating Lubricant: This is your first line of attack. Apply a *small amount* of a quality penetrating lubricant like WD-40 (though this is a temporary solution) or *preferably* a dedicated contact cleaner (like DeoxIT) directly into the keyhole. Work the key in and out gently several times to distribute the lubricant. Let it sit for a few minutes before trying again. Avoid excessive lubrication; it can attract dirt. Use compressed air to blow out excess.
* Graphite Lubricant: A dry graphite lubricant, applied sparingly, is a better long-term solution than WD-40. It lubricates without attracting dirt and grime.
3. More Involved Solutions (If simple solutions fail):
* Cleaning: If the lubricant doesn't help, the switch may need a thorough cleaning. This often requires removing the ignition switch bezel (the plastic trim around the ignition). You can find detailed instructions on YouTube by searching "2000 Ford Focus ignition switch removal." Once removed, carefully clean the switch contacts with contact cleaner and a small brush. Pay close attention to the tumbler mechanism. Reassemble carefully.
* Ignition Switch Replacement: This is the most likely solution if cleaning doesn't work. Replacing the ignition switch is a more involved job that often requires specialized tools and knowledge of automotive electronics. You'll need a new ignition switch (ensure you get the correct part number for your vehicle). Again, YouTube videos are a valuable resource. Caution: Incorrect installation can lead to electrical issues or even immobilizer problems. Consider this job only if you're comfortable with automotive repair or if you plan to take it to a qualified mechanic.
Important Considerations:
* Safety: Disconnect the negative battery cable before attempting any repair work on the ignition system. This prevents accidental shorts and protects you from electrical shock.
* Complexity: Working on the ignition system can be complex. If you're not comfortable with automotive repair, take your car to a qualified mechanic. Improper repair can lead to further damage or even safety hazards.
* Immobilizer System: The 2000 Ford Focus might have an immobilizer system. Replacing the ignition switch may require reprogramming the system, which usually necessitates a trip to a dealership or a specialized auto locksmith.
Remember to always consult your owner's manual or a repair manual specific to your 2000 Ford Focus for detailed instructions and diagrams before attempting any repair. YouTube videos can be helpful, but always cross-reference information with reputable sources.
