It’s a common scenario: you approach your Chevrolet, press the unlock button on your key fob, and nothing happens. A malfunctioning key fob can be frustrating and inconvenient. Before you rush to the dealership or assume the worst, know that many key fob issues are easily resolvable at home. This guide will walk you through troubleshooting steps and solutions to get your Chevrolet key fob working again.
Common Reasons Why Your Chevy Key Fob Stopped Working
Understanding why your Chevy key fob isn’t working is the first step towards fixing it. Here are the most frequent culprits:
1. Dead or Low Battery
The most common reason for a key fob malfunction is a dead or weak battery. Chevrolet key fobs, like most keyless entry remotes, are powered by a small coin cell battery, typically a CR2032 or DL2032 type. These batteries have a lifespan of about 3 years, but heavy usage or extreme temperatures can shorten their life. When the battery starts to weaken, you might notice a reduced range, meaning you need to be closer to your car for the fob to work. Eventually, it will stop working altogether.
2. Key Fob Circuitry Issues
While less frequent than battery problems, issues within the key fob’s internal circuitry can also cause it to fail. This could be due to physical damage from drops, exposure to moisture, or even corrosion over time. If you’ve noticed your key fob has been damaged or exposed to liquids, internal circuitry problems are a possible cause.
3. Car Alarm System Problems
In some cases, a deactivated or malfunctioning car alarm system can interfere with key fob operation. Modern car alarms and keyless entry systems are integrated, and issues with the alarm can sometimes prevent the key fob signals from being recognized by your Chevy.
How to Troubleshoot and Fix a Chevy Key Fob
Before assuming a serious problem, try these simple troubleshooting steps:
1. Battery Replacement: The First Step
Replacing the battery is the easiest and most often successful fix.
- Identify the Battery Type: Check your owner’s manual or open the key fob (usually by gently prying it apart with a small screwdriver or coin) to identify the correct battery type (CR2032 or DL2032).
- Purchase a New Battery: These batteries are widely available at drugstores, supermarkets, and online retailers.
- Replace the Battery: Carefully remove the old battery and install the new one, ensuring the polarity (+ and – signs) is correct.
- Test the Key Fob: After replacement, test the key fob buttons to see if it now operates your Chevy’s locks and other functions.
2. Check for Button Issues
Sometimes, the buttons on your key fob can become sticky or jammed due to dirt, debris, or wear and tear.
- Inspect the Buttons: Visually check if any buttons appear stuck or are not moving freely.
- Clean the Buttons: Use compressed air or a soft brush to clean around the buttons. You can also gently use a cotton swab lightly dampened with isopropyl alcohol to clean around the button edges.
- Press the Buttons Repeatedly: Sometimes, repeatedly pressing a button can dislodge any minor obstructions.
3. Ensure Key Fob and Car Connection
While less likely with modern key fobs, ensure there’s no obstruction between your key fob and the car, especially if you’re experiencing range issues. Try using the key fob closer to the vehicle.
4. Reprogramming Your Chevy Key Fob
If a battery replacement doesn’t work, or if your key fob seems to be functioning erratically, reprogramming might be necessary. Here are a couple of methods:
Method 1: Key Cycling Reprogramming
This method is often outlined in Chevy owner’s manuals.
- Insert and Turn Key: Insert your Chevy key into the ignition.
- Cycle Ignition: Turn the ignition to the “ON” position ten times in quick succession (within 10 seconds), leaving it in the “ON” position on the tenth turn.
- Turn Off Ignition: Turn the key to the “OFF” position.
- Press Accelerator: Within 5 seconds, press the accelerator pedal down five times.
- Turn Ignition On Again: Within 10 seconds, turn the key back to the “ON” position and then remove it.
- Press Accelerator Once: Press the accelerator pedal down once.
- Turn Ignition Off and Remove Key: Turn the key to the “OFF” position and remove it within 5 seconds. You should hear a chime or door lock sound indicating programming mode is exited.
- Test New Remote: Press a button on your key fob. The car doors should lock or unlock, confirming successful programming.
Method 2: Programming with Two Working Keys
This method is used when adding a new key fob and requires two already working keys.
- Insert First Working Key: Insert your first working key into the ignition and turn it to the “ON” position.
- Insert Second Working Key: Within 5 seconds, remove the first key and insert your second working key, turning it to the “ON” position.
- Turn Off Ignition (Second Key): Within 10 seconds, turn the second key back to the “OFF” position and remove it.
- Press Accelerator Pedal: Within 5 seconds, press the accelerator pedal down five times.
- Insert First Working Key Again: Within 10 seconds, insert the first working key back into the ignition and turn it to the “ON” position.
- Press Accelerator Pedal Once: Within 5 seconds, press the accelerator pedal down once.
- Turn Off Ignition (First Key) and Remove: Turn the first key to the “OFF” position and remove it from the ignition.
- Test New Remote: Press the lock or unlock button on your new key fob. The car should respond, indicating successful programming.
Important Note: Programming procedures can vary slightly between Chevy models and years. Always consult your owner’s manual for the most accurate instructions for your specific vehicle.
When to Consider Key Fob Replacement
If troubleshooting and reprogramming don’t resolve the issue, your Chevy key fob itself might be faulty. Consider replacement if:
- Physical Damage: The key fob is visibly cracked, broken, or water-damaged.
- Circuitry Failure Suspected: Even after battery replacement, the fob remains unresponsive, suggesting internal electronic failure.
- Button Wear and Tear: Buttons are excessively worn or damaged, affecting their function.
Chevy Key Fob Replacement Cost and Options
The cost of replacing a Chevy key fob can vary.
- Dealership: Dealerships can program and sell you a new key fob, but this is generally the most expensive option, ranging from $70 to $200 or more, including programming fees.
- Automotive Locksmith: Locksmiths specializing in automotive keys often offer key fob replacement and programming services at potentially lower prices than dealerships.
- Online Retailers & DIY Programming: You can purchase aftermarket key fobs online, often at a lower cost. However, programming these yourself can be complex and may require special tools or diagnostic equipment, depending on your Chevy model. Some online retailers may offer programming instructions or services.

Key Fob Repair vs. Replacement
While some specialized services might offer key fob repair, in most cases, replacement is the more practical and reliable solution. Key fobs are not designed for easy repair, and internal component fixes can be unreliable. Replacing the entire fob ensures you get a fully functional and warrantied unit.
Conclusion
A non-working Chevy key fob can be a minor inconvenience or a major headache. Fortunately, many issues are easily resolved with simple troubleshooting steps like battery replacement or reprogramming. By following this guide, you can confidently diagnose and potentially fix your “Chevrolet Key Fob Not Working” problem and avoid unnecessary trips to the mechanic. If you’ve exhausted these steps and your key fob remains unresponsive, consider professional replacement options to regain full keyless entry functionality for your Chevrolet.
