You’re locked out of your car, and your plastic car key is broken. It’s a frustrating situation, but don’t panic! This guide will help you understand the common problems with broken plastic car keys, provide step-by-step solutions, and offer expert advice to get you back on the road.
Common Causes of Broken Car Keys
The plastic housing of your car key is designed to protect the internal electronic components, but it’s susceptible to damage from wear and tear, accidental drops, and even exposure to extreme temperatures. Some common causes of broken plastic car keys include:
- Key Fob Cracks: Cracks can appear on the key fob’s surface, often stemming from the key being dropped or squeezed.
- Broken Key Blade: The key blade itself can break if it’s bent or forced into the lock.
- Worn Plastic Housing: Over time, the plastic housing can become worn and brittle, making it more prone to breakage.
- Internal Component Failure: The electronic components inside the key fob can malfunction, leading to the housing being damaged.
Identifying the Issue
Before diving into a fix, it’s essential to identify the exact problem with your key.
- Inspect the Key Fob: Look for cracks, chips, or other visible damage to the plastic housing. Check if the key blade is broken or bent.
- Test Key Functionality: Try to use the key to unlock your car. If the key doesn’t work, the problem might be with the internal electronics or a broken blade.
Fixing a Broken Plastic Car Key
Once you’ve identified the issue, you can proceed with the appropriate solution.
1. Fixing a Cracked or Chipped Key Fob
- Super Glue or Epoxy: For minor cracks or chips, applying a strong adhesive like super glue or epoxy can temporarily repair the damage.
- Epoxy Putty: For larger cracks or gaps, you can use epoxy putty to fill the void and reinforce the plastic.
Expert Tip: “If you’re using epoxy, make sure to carefully clean the area and allow it to fully cure before using the key.” – Mark Johnson, Automotive Technician
2. Fixing a Broken Key Blade
- Replace the Blade: If the key blade is broken, you’ll need to replace it. You can purchase a replacement blade at most auto parts stores or online.
- Key Blade Cutting: Once you have the replacement blade, you’ll need to get it cut to match your car’s lock. You can take the blade to a local locksmith or an auto parts store that offers key cutting services.
Expert Tip: “Always ensure the new blade is cut by a qualified professional to avoid damage to your car’s lock.” – Sarah Lee, Locksmith
3. Replacing the Plastic Housing
- Purchase a New Housing: If the entire plastic housing is damaged or worn, you can purchase a replacement housing for your car key online or at an auto parts store.
- Transfer Components: Carefully transfer the key blade, battery, and electronic components from your old housing to the new one.
Expert Tip: “Be careful when transferring the electronic components to avoid damaging them. If you’re not comfortable with this, consider taking it to a locksmith or a specialized key repair shop.” – Richard Smith, Automotive Specialist
4. Repairing Internal Components
If the internal components of your key fob are malfunctioning, it’s best to take it to a qualified locksmith or a specialized key repair shop. They have the tools and expertise to diagnose and repair the issue.
Preventing Future Breakage
Here are some tips to help prevent your car key from breaking in the future:
- Handle with Care: Treat your car key with care and avoid dropping or squeezing it.
- Keep it Clean: Dust and dirt can accumulate on the key fob, potentially causing damage to the plastic housing. Clean it regularly with a soft cloth and mild soap.
- Store Properly: Store your car key in a safe and dry place when not in use.
What to Do if the Key Still Doesn’t Work
If you’ve tried all of these solutions, and your car key still doesn’t work, you may need to replace the key fob entirely. You can contact your car dealership or a specialized key repair shop for a replacement.
