Identifying Your Chevy Key Fob Type
Identifying the type of key fob you have for your Chevy vehicle is crucial before you can replace its battery. Chevy has employed various key fob designs over the years, and each type may have unique steps for battery replacement.
To determine your key fob type, follow these steps:
- Examine the physical appearance: Observe the shape, size, and button arrangement of your key fob. Different Chevy models and years feature distinct key fob designs, so the physical characteristics can provide clues about its type.
- Check the key ring attachment: Notice how the key fob attaches to your keychain. Some key fobs use a traditional metal ring, while others employ a more modern clip-on mechanism. The attachment method can further narrow down your key fob type.
- Refer to your vehicle’s owner’s manual: The owner’s manual typically includes a section dedicated to key fob information. It should provide a detailed description of the key fob type used for your specific Chevy model and year. Consulting the manual can give you the most accurate identification.

Identifying the battery compartment on your Chevy key fob is crucial for a successful battery replacement. The location of this compartment may vary slightly depending on the model and year of your Chevrolet vehicle. Here are detailed steps to guide you in finding the battery compartment:
Step 1: Inspect the Sides
Carefully examine the sides of your key fob. You may find a small indentation or release button on one of the edges. Press or slide the button to release the battery cover.
Step 2: Check the Back
If there is no release button on the sides, check the back of the key fob. Look for a small screw or a latch that secures the battery cover. Use a small screwdriver or a coin to loosen the screw or disengage the latch.
Step 3: Remove the Key
In some key fobs, you might need to remove the metal key blade before accessing the battery. Locate the small button or lever at the base of the key blade and press it to release the key.
Step 4: Separate the Fob
Once you have removed the key or released the cover, carefully separate the two halves of the key fob. Be gentle to avoid damaging the internal components.
Step 5: Identify the Battery
Inside the battery compartment, you will find a small, coin-shaped battery. The battery may be secured in a holder or have a film covering its terminals. Carefully remove the old battery and note its size, voltage, and positive and negative terminals. Refer to the following table for common battery types used in Chevy key fobs:
Battery Type Voltage CR2025 3V CR2032 3V CR1632 3V Removing the Old Battery
Locate the small button on the back of the key fob. Press and hold the button to release the metal key blade.
With the key blade removed, slide the plastic cover apart at the seam. Be careful not to damage the buttons or internal components.
Identify the small, round battery inside the housing. Use a flathead screwdriver or a pick tool to gently pry the battery out of its compartment.
Inspect the battery for any signs of damage or corrosion. If the battery is damaged, replace it with a new one of the same size and type. Refer to the table below for the specific battery required for your Chevy key fob.

Inserting the New Battery
With the circuit board and battery holder removed, it’s time to insert the new battery. Here’s a step-by-step guide:
1. Check Battery Orientation
Before inserting the battery, check its orientation. The positive (+) terminal should be facing up or towards the circuit board.
2. Slide in the Battery
Carefully slide the new battery into the battery holder. Ensure it fits snugly in place.
3. Secure the Battery
Using a small screwdriver or pry tool, gently push down on the battery terminals to secure it in place.
4. Check the Polarity
Double-check that the battery is inserted with the correct polarity. The positive terminal (+) should be facing away from the circuit board.
5. Test the Key Fob
Once the battery is inserted, put the circuit board back into the key fob housing and press any button. If the key fob lights up or functions correctly, the battery is installed properly.
6. Replace the Battery Cover
Locate the battery cover and carefully snap it back into place.
7. Reset the Key Fob (Optional)
In some cases, resetting the key fob may be necessary after replacing the battery. Refer to your vehicle’s user manual for specific instructions on resetting.
Note: For CR batteries, the positive terminal is usually the larger end with the “+” symbol, while the negative terminal is the smaller end.
Closing the Key Fob Casing
1. Match the alignment marks on the two halves of the key fob casing. Ensure that the casing is aligned correctly to prevent any gaps or misalignment.
2. Gently press along the edges of the casing to snap it back together. Start from one corner and work your way around, applying even pressure to ensure a secure closure.
3. Ensure a snug fit by pressing down firmly on the casing until you hear or feel a click, indicating that it is securely closed.
4. Check for any gaps or loose areas in the casing. If any, apply additional pressure to ensure a tight fit.
5. Double-check that the buttons are functioning properly after closing the casing. Press each button to ensure they activate the intended function.
6. Inspect the key fob for any damage or loose components. If you notice anything unusual, re-open the casing and check for any misalignment or loose parts.
7. Confirm that the key fob is fully closed and securely assembled. If necessary, readjust the alignment or apply additional pressure to ensure a secure fit.
8. **Additional Considerations for Advanced Key Fobs:**
Certain advanced key fobs may have additional features or components that require special attention when closing the casing:
Component Additional Steps Proximity Sensor Ensure the sensor is properly aligned and positioned within the casing before closing. Emergency Key Insert the emergency key into the designated slot in the casing before snapping it closed. Integrated Display Check for any loose connections or misalignment of the display before closing the casing. By following these detailed steps, you can ensure that your Chevy key fob casing is securely closed, protecting the battery and ensuring proper functionality.
Reattaching the Physical Key (If Removed)
If you’ve removed the physical key from the fob, you’ll need to reattach it before using it. Here’s a step-by-step guide on how to do this:
- Locate the small hole on the side of the key fob, near the base.
- Insert the metal key into the hole and push gently until you feel it click into place.
- Slide the key back into the fob until it snaps securely into position.
Additional Tips:
- Ensure that the key is fully inserted and clicked into place to prevent it from coming loose.
- If you have difficulty inserting the key, try applying a small amount of pressure while pushing it into the hole.
- If the key still won’t insert, check for any debris or obstructions in the hole and remove them gently using a small tool like a toothpick or needle.
Step Action 1 Locate the small hole on the side of the key fob. 2 Insert the metal key into the hole and push gently. 3 Slide the key back into the fob until it snaps into position. Testing the Key Fob Functionality
To ensure that the key fob battery needs replacing, follow these steps:
- Check the key fob’s range: Attempt to lock and unlock your vehicle from a distance. If the range is diminished, the battery may be weak.
- Observe the LED indicator: When pressing the key fob buttons, the LED light should illuminate brightly. If the light is dim or not visible, it suggests a battery issue.
- Test multiple buttons: Press each button on the key fob (lock, unlock, trunk, etc.). If some buttons do not function while others do, it may indicate a battery problem.
- Inspect the battery contacts: Look for any signs of corrosion or damage on the battery contacts inside the key fob. Clean any debris or corrosion with a cotton swab and rubbing alcohol.
- Use a multimeter: If you have a multimeter, you can measure the voltage of the battery. A fully charged battery should read around 3 volts. Less than 2.5 volts indicates a low battery.
- Try a spare key fob (if available): If you have a spare key fob, try using it to operate your vehicle. If the spare key fob works, the issue likely lies with the battery in your primary key fob.
