This comprehensive guide will walk you through everything you need to know about your 2007 Toyota Highlander key fob, specifically part number 89742-42120.
Understanding Your Key Fob: More Than Just Unlocking Doors
The 89742-42120 key fob isn’t just a remote to lock and unlock your Highlander; it’s a sophisticated piece of technology that communicates with your vehicle’s immobilizer system. This system ensures only your key fob can start your car, adding an extra layer of security.
Common Issues with a 2007 Toyota Highlander Key Fob
Like any electronic device, your key fob can experience wear and tear. Here are some common problems:
- Decreased Range: If you find yourself standing closer and closer to your car to unlock it, the battery in your key fob is likely dying.
- Unresponsive Buttons: Over time, the buttons on your key fob can wear out. This is often indicated by needing to press a button multiple times to get it to work.
- Key Fob Programming Errors: After replacing the battery, you might experience issues with the key fob communicating with your car. This usually requires reprogramming.
Troubleshooting Tips: Before You Head to the Dealer
Before you spend money at a dealership, try these troubleshooting tips:
- Replace the Battery: This is the easiest and often the most effective solution for many key fob issues. You can find the correct battery type in your owner’s manual.
- Reprogram Your Key Fob: Instructions for reprogramming your key fob are often found in your owner’s manual. It’s a relatively straightforward process.
- Check for Interference: Other electronic devices or signals can sometimes interfere with your key fob’s signal.
When to See a Professional
If troubleshooting doesn’t solve the problem, it’s best to consult a professional locksmith or dealership. They have the expertise and tools to diagnose and fix more complex key fob issues, such as:
- Damaged Key Fob: Physical damage from drops or water can render your key fob useless.
- Internal Component Failure: Issues with the key fob’s internal circuitry will likely require professional repair or replacement.
- Immobilizer System Malfunction: Problems with the car’s immobilizer system itself will necessitate a visit to a qualified mechanic.
Choosing the Right Replacement Key Fob
If your key fob is beyond repair, you’ll need a replacement. Here are a few options:
- Dealership: You can get an OEM (Original Equipment Manufacturer) key fob from the dealership, guaranteeing compatibility. However, this is often the most expensive option.
- Locksmith: Many locksmiths can provide and program OEM or aftermarket key fobs at a lower cost than dealerships.
- Online Retailers: Online marketplaces offer various key fobs, but exercise caution. Ensure you choose a reputable seller and confirm the key fob’s compatibility with your specific Highlander model.
Keeping Your Key Fob in Top Shape
Here are some tips to prolong the life of your key fob:
- Handle with Care: Avoid dropping your key fob or exposing it to extreme temperatures or moisture.
- Use a Protective Case: A case can help protect your key fob from everyday wear and tear.
- Replace the Battery Regularly: Don’t wait for your battery to die completely. Replacing it every year or two can prevent unexpected issues.
