It’s a frustrating moment every car owner dreads: you’re in a hurry, you go to start your car, and suddenly – snap! Your key breaks off right in your key fob. Now you’re left with a broken key fob and a key stuck either in the ignition or completely separated. Don’t panic, you’re not alone, and there are several ways to address this common car key problem.
This guide, brought to you by the automotive experts at keyfobprog.com, will walk you through the steps you can take when your key breaks off your key fob. We’ll cover DIY fixes, replacement options, and how to get back on the road quickly and affordably.
Understanding Why Your Key Fob Broke
Before we jump into solutions, let’s briefly understand why this happens. Car key fobs, especially older ones, can become brittle over time due to wear and tear, temperature changes, and the constant twisting motion of starting your car. The point where the metal key blade connects to the plastic fob housing is a common weak spot.
Immediate Actions When Your Key Breaks
- Don’t Force Anything: If the key is stuck in the ignition, do not try to force it out. This could cause further damage to your ignition system.
- Assess the Damage: Carefully examine the broken key fob and the key blade. Is the blade still in the ignition? Is the damage to the plastic housing, the metal key, or both?
- Gather the Pieces: Collect all parts of your broken key fob. You might be able to reuse some components.
DIY Fixes and Replacement Options
Depending on the extent of the damage and your comfort level with DIY repairs, you have a few options:
1. DIY Key Fob Repair with a Replacement Shell
This is often the most cost-effective solution if the electronic components of your key fob are still working and only the plastic shell is damaged. You can purchase a replacement key fob shell online, and swap the internal parts from your old fob into the new one.

Websites like AliExpress offer a wide variety of replacement key fob shells for different car models, often at very reasonable prices. For example, if you drive a Chevrolet Cruze, you can find shells specifically designed for your car.
Steps for DIY Shell Replacement:
- Purchase a compatible replacement shell: Ensure it matches your car make, model, and the number of buttons on your original fob.
- Carefully open your old key fob: You may need a small screwdriver or prying tool.
- Transfer the internal components: Gently remove the circuit board, transponder chip (if separate), and battery from your old shell and place them into the new shell.
- Swap the key blade: If your new shell comes with a blank key blade, you’ll need to either swap the blade from your old fob (if it’s undamaged) or get the new blank blade cut to match your car’s key.
- Reassemble the new key fob: Close the replacement shell securely.

2. Buying a Complete Replacement Key Fob
If the damage is more extensive, or you’re not comfortable with DIY repairs, you can purchase a complete replacement key fob. This option typically involves buying a new key fob with a blank key blade, getting the blade cut, and then programming the new fob to work with your car.

You can find replacement key fobs online, at dealerships, or from locksmiths. When purchasing online, ensure compatibility with your car’s make, model, year, and features (like remote start or proximity entry).
Key Cutting and Programming:
-
Key Cutting: You’ll need to get the new key blade cut to match your car’s ignition. This can be done at a dealership, a locksmith, or some hardware stores.
-
Key Programming: Modern car keys often need to be programmed to communicate with your car’s immobilizer system. Some vehicles allow for DIY programming if you have an existing working key. The original article mentions a DIY programming method for Chevrolet Cruze vehicles:
“Get in the car, close the doors, put the old, programmed fob in the ignition and turn it to on for a second then then off again. Remove the old key. Within 10 seconds, put the new fob in the ignition and turn it to on then off again. It should now be programmed.”
However, for many vehicles, especially newer models, programming requires specialized equipment and may need to be done by a dealer or a locksmith. If you don’t have a working key, the process can be more complex and time-consuming, potentially taking up to 30 minutes using a specific procedure outlined in the original article.
3. Aftermarket and Local Locksmith Solutions
Consider checking with local hardware stores or automotive locksmiths. They may offer aftermarket key fob solutions or replacement services. Locksmiths often provide key cutting and programming services as well, and can be a convenient alternative to dealerships.
Cost Considerations
The cost to fix your broken key fob will vary depending on the chosen solution:
- DIY Shell Replacement: The cheapest option, typically costing just the price of the replacement shell (often under $20).
- Complete Replacement Fob (Online Purchase): Mid-range cost, with the fob itself costing anywhere from $20 to $100+, plus key cutting and potential programming fees.
- Dealership or Locksmith Replacement: Generally the most expensive option, potentially costing $200 or more, but offers convenience and professional service.
Conclusion
Having your key break off your key fob is a frustrating but resolvable issue. By understanding your options – from DIY repairs with replacement shells to professional replacement services – you can choose the best solution for your needs and budget. Remember to always prioritize getting a functional key fob to ensure the security and convenience of your vehicle. Don’t let a broken key fob leave you stranded!
