Losing or damaging your Chevy key fob can be a frustrating experience. Fortunately, programming a new key fob for your Chevy vehicle can often be done at home, saving you time and money compared to dealership programming. This guide will walk you through the process of how to program a Chevy key fob, explore the differences between OEM and aftermarket fobs, and offer troubleshooting tips based on real-world experiences.
Understanding Chevy Key Fob Programming
Chevy key fobs are more than just simple remote controls; they are integral to your vehicle’s security system. Programming ensures that your key fob is correctly recognized by your car, allowing you to lock, unlock, start the engine (in some models), and utilize other remote features. The process typically involves entering a specific sequence of actions within your vehicle that puts it into programming mode, allowing it to learn the new key fob’s signal.
There are generally two types of key fobs you might consider:
- Original Equipment Manufacturer (OEM) Key Fobs: These are genuine Chevy key fobs, manufactured by or for General Motors. They are designed to work seamlessly with your vehicle’s system.
- Aftermarket Key Fobs: These are manufactured by third-party companies and are often less expensive than OEM fobs. However, as we’ll see, they can sometimes present compatibility or programming issues.
Step-by-Step Guide to Programming an OEM Chevy Key Fob (DIY Method)
While specific steps can vary slightly depending on your Chevy model and year, here’s a general procedure for programming an OEM Chevy key fob yourself. Always consult your owner’s manual for the most accurate instructions for your specific vehicle.
- Get in your Chevy vehicle and close all doors. Ensure all doors are fully closed for the programming sequence to work correctly.
- Insert your existing, already programmed key into the ignition. If you don’t have an existing programmed key, this DIY method might not work, and you may need professional assistance.
- Turn the ignition to the “ON” position. This is the position just before you would start the engine. Do not start the engine. Leave the key in the “ON” position.
- Press and hold the “Unlock” button on the driver’s side door. Keep holding the “Unlock” button down.
- While holding the “Unlock” button, turn the ignition key to the “OFF” position, then back to the “ON” position, three times in rapid succession. This means going ON-OFF-ON-OFF-ON while continuously holding the “Unlock” button.
- Release the “Unlock” button. You should hear the door locks cycle (lock then unlock). This indicates that your Chevy is now in programming mode.
- Immediately take your new, unprogrammed key fob and press and hold both the “Lock” and “Unlock” buttons simultaneously for about 15 seconds.
- After 15 seconds, release both buttons. Again, you should hear the door locks cycle, confirming that the new key fob has been successfully programmed.
- Turn the ignition key to the “OFF” position and remove the key.
- Test your new key fob. Press the buttons to lock and unlock the doors, and if your Chevy model has remote start, test that function as well.
If the programming is successful, your new key fob should now operate all the functions. If you don’t hear the locks cycle at any point, or if the key fob doesn’t work after these steps, repeat the process carefully, ensuring each step is followed precisely.

OEM vs. Aftermarket Key Fobs: Real-World Experiences and Potential Pitfalls
Choosing between an OEM and aftermarket key fob often comes down to price, but as one Chevy owner discovered, cheaper isn’t always better. Their experience highlights crucial differences and potential issues:
- Programming Compatibility: OEM key fobs are designed specifically for your vehicle, increasing the likelihood of successful DIY programming. Aftermarket fobs, while sometimes advertised as compatible, may not always program correctly using the standard in-car procedures.
- Build Quality and Reliability: OEM fobs generally have better build quality. The user in the original forum post noted that their aftermarket fob felt mechanically inferior, with buttons lacking tactile feedback. This can lead to functional problems and a less satisfying user experience.
- “Theft Deterrent” Mode Issues: Attempting to use an incorrectly programmed or incompatible key fob can potentially trigger your Chevy’s “Theft Deterrent” system. In some cases, this might lead to vehicle malfunctions, such as battery drain or starting problems, as experienced by the Chevy Bolt owner. While not always severe, these issues can be inconvenient and stressful.
- Dealer and Locksmith Programming: While some aftermarket fob retailers claim no programming difference between OEM and aftermarket, dealerships and locksmiths often have specialized tools and expertise to program both types. However, some may charge more or express less confidence in programming aftermarket fobs due to potential compatibility uncertainties.
Key Takeaway: While aftermarket key fobs might seem like a budget-friendly option, the potential for programming headaches, reliability issues, and even vehicle system complications makes OEM key fobs a generally safer and more reliable choice.
When to Seek Professional Key Fob Programming
If you encounter any of the following situations, it’s best to seek professional help from a Chevy dealership or a qualified automotive locksmith:
- DIY Programming Fails: If you’ve carefully followed the DIY programming steps multiple times and your new key fob still doesn’t work, professional programming is likely necessary.
- No Existing Programmed Key: The DIY method typically requires an already programmed key. If you’ve lost all your key fobs, you’ll need a professional to program new ones.
- Aftermarket Key Fob Issues: If you’re using an aftermarket key fob and experiencing programming difficulties, a professional might be able to program it, but success isn’t guaranteed. They may recommend switching to an OEM fob for better compatibility.
- “Theft Deterrent” Mode Activation or Other Vehicle Issues: If you suspect your key fob programming attempts have triggered the “Theft Deterrent” system or are causing other vehicle malfunctions, seek professional help immediately to diagnose and resolve the problem.
Conclusion: Choosing the Right Path for Your Chevy Key Fob Programming
Programming a Chevy key fob can be a straightforward process, especially when using an OEM fob and following the correct DIY steps. However, it’s important to be aware of the potential pitfalls of aftermarket fobs and to recognize when professional programming is the more prudent option. Investing in an OEM key fob and, if needed, professional programming services can save you from potential headaches and ensure reliable key fob functionality for your Chevy vehicle.
