A broken car key plastic can be a frustrating experience. Not only does it make your key look worn, but it can also make it difficult to use. Fortunately, you can often fix a broken car key plastic yourself without having to pay a locksmith. In this article, we’ll guide you through the steps on how to repair your car key plastic, from basic fixes to more advanced techniques.
Assessing the Damage
Before you attempt any repairs, you need to assess the damage to your car key plastic. There are a few common issues you might encounter, including:
- Cracked or broken key casing: This is the most common issue. The plastic casing around your car key may crack or break if you drop the key or accidentally apply too much pressure.
- Missing or damaged key teeth: The metal teeth of your car key can get bent or damaged, making it impossible to unlock or start your car.
- Worn or faded key buttons: If your key has buttons for remote functions, they may become worn or faded over time, making them difficult to press.
Fixing a Cracked or Broken Key Casing
For a cracked or broken key casing, you have a few options:
1. Use Super Glue or Epoxy
- Gather materials: Super glue, epoxy, rubber gloves, and a small brush or toothpick.
- Clean the surfaces: Clean the broken pieces thoroughly using a damp cloth. Let them dry completely.
- Apply adhesive: Using the brush or toothpick, apply a thin layer of super glue or epoxy to the broken edges.
- Clamp the pieces together: Clamp the broken pieces together and allow the glue or epoxy to dry completely. This may take several hours depending on the adhesive.
2. Replace the Key Casing
If the crack is too severe or the plastic is too damaged, replacing the entire key casing might be your best option. You can get a replacement key casing from:
- Dealership: This is the most expensive option but guarantees a genuine part.
- Online retailers: Numerous websites sell replacement key casings for various car models at cheaper prices.
- Local locksmith: Some locksmiths offer replacement key casings.
3. 3D Printing a New Casing
For more advanced users, you can consider 3D printing a new key casing if the original one is beyond repair. This requires access to a 3D printer and a 3D model of your specific key.

Fixing Missing or Damaged Key Teeth
For damaged key teeth, you have two options:
1. File the Teeth
- Use a fine-grit file: Carefully file down the damaged teeth to match the shape of the remaining teeth. This requires patience and a steady hand.
- Test fit: Test the key in the car’s lock and file down any remaining rough spots.
2. Replace the Key Blade
- Visit a locksmith: Most locksmiths can cut a new key blade for your existing key.
- Remove the existing key blade: Remove the existing key blade from the casing. This often requires a small screwdriver or a specialized key tool.
- Install the new blade: Install the new key blade into the casing and ensure it sits securely.
Fixing Worn or Faded Key Buttons
- Clean the buttons: Use a cotton swab dipped in rubbing alcohol to clean the key buttons.
- Replace the buttons: If the buttons are severely worn or faded, you can replace them with new ones. Contact your car dealership or look for replacement buttons online.
Prevention Tips
- Protect your key: Store your car key in a safe place away from heat, moisture, and extreme temperatures.
- Avoid dropping your key: Handle your car key with care to prevent damage to the plastic casing.
- Clean your key regularly: Clean your car key regularly to prevent dirt and grime from accumulating.
Expert Tip: “Regularly cleaning your key buttons can extend their lifespan and improve their functionality.” – Sarah Jones, Automotive Technician
