You’ve been there. You’re rushing to get to work, you grab your keys, and the car doesn’t start. You try again, and again, but the key just won’t turn. You check the battery, but it’s fine. So what’s the problem? It could be your car key.
Old car keys can become worn, damaged, or simply stop working properly. It’s frustrating, but don’t despair! There are several things you can try to fix an old car key that doesn’t work. We’ll cover some common problems and solutions in this article.
Identifying the Problem with Your Car Key
The first step is to figure out what’s wrong with your key. Here are some common issues:
Key Is Worn or Damaged
Worn or Damaged Car Key
- The Key Blade Is Worn or Bent: This is the most common problem. The key blade can wear down over time, especially if it’s used frequently. It might not be able to fully engage the ignition cylinder.
- The Key Fob Is Damaged: The key fob is the remote part of the key. If it’s damaged, it might not be able to send signals to the car. This could prevent the car from starting, or it might not be able to unlock the doors.
Key Is Not Properly Aligned
The key might be properly working, but it may not be inserted in the right position. This is more common with keys that are worn, have a bent key blade, or if the ignition cylinder is worn.
Key Is Not Receiving Power
Sometimes, the key might be receiving power, but not enough to start the car. This is often a sign that the car’s battery needs to be replaced.
Fixing a Worn or Damaged Key
Here are some solutions to try if your car key is worn or damaged:
1. Clean the Key
- Clean the Key Blade: Use a toothbrush and some rubbing alcohol to clean the key blade. Make sure to scrub both sides of the blade. This can remove dirt, grime, and debris that might be preventing it from turning smoothly.
- Clean the Key Fob: If you have a key fob, you can clean it with a soft cloth and some mild soap. Make sure to avoid getting any moisture inside the fob.
2. Try Replacing the Key Battery
- Find the Battery: The key fob has a small compartment where the battery is located. This compartment is typically hidden behind a small cover or slider.
- Replace the Battery: Once you’ve found the battery, gently pry it out with a flathead screwdriver. Make sure you replace it with a new, fresh battery of the correct size and type. Refer to the key fob’s documentation if you need help.
3. Adjust or Replace the Key Blade
- Try to Straighten the Key Blade: If the key blade is bent, you can try to gently straighten it with a pair of pliers. However, be careful not to bend the blade too much, as this could damage it further.
- Replace the Key Blade: If you can’t straighten the key blade, you’ll need to replace it. You can get a new key blade from an automotive locksmith or a key shop. Make sure to get a key blade that is compatible with your car.
Dealing with a Key Not Properly Aligned
If your key is not properly aligned, it might need a little bit of adjustment. It’s important to note that some keys are designed to be aligned in specific ways, while others are not.
1. Adjust the Key Blade
If your key blade is not aligned correctly, you can try to adjust it. This is a bit more complex, and we recommend you seek out the expertise of a professional locksmith or a key shop.
2. Clean the Ignition Cylinder
A dirty ignition cylinder could be preventing the key from properly aligning. Use a can of compressed air to remove dust and debris from the ignition cylinder. Be careful not to get any moisture inside the cylinder.
Handling Keys Not Receiving Power
If the key isn’t receiving power, it may be a sign of a more serious issue. Here’s what to check:
1. Car Battery
- Check the Battery: The first thing to check is the battery in your car. If the battery is dead or weak, it might not be providing enough power to the key.
- Replace the Battery: If the battery is dead, you can replace it with a new one. If you’re not comfortable replacing the battery yourself, take it to a mechanic.
2. Car’s Electrical System
- Check the Electrical System: If the battery is fine, there might be an issue with the car’s electrical system. This could be caused by a faulty fuse or a problem with the car’s wiring.
- Get Professional Help: If you suspect there’s a problem with the car’s electrical system, take it to a mechanic.
Tips and Precautions
- Be Careful Handling the Key: Be careful when handling the key, especially the key blade. If you bend or damage the blade, it could make the problem worse.
- Don’t Force the Key: If the key doesn’t turn easily, don’t force it. This could damage the ignition cylinder.
- Consider Using a Professional Locksmith: If you’re not comfortable working with car keys, consider taking your car to a professional locksmith. They have the tools and expertise to fix your key or replace it.
