Lost your key fob or need to program a new one for your 2002 Chevy Impala? You’re in luck! Programming your key fob at home is possible, and we’ll show you two methods to get the job done. Whether you have access to a Tech2 scan tool or not, follow these step-by-step instructions to program your 2002 Impala key fob quickly and easily.
Method 1: Key Fob Programming Without a Tech2 Scan Tool
This method is your go-to if you don’t have access to a professional scan tool like a Tech2. It utilizes your car’s radio system to enter programming mode. Here’s how:
-
Get Inside: Enter your 2002 Impala and ensure you are in the driver’s seat. Insert your ignition key into the ignition switch.
-
Turn the Key to “On”: Turn your key to the “On” position. This will power the car’s electronics, but do not start the engine.
-
Access Radio Settings: Locate the “DISP” button on your car radio. Press and hold the “DISP” button for approximately five seconds. You should see the settings menu appear on the radio display.
-
Navigate to “FOB PROG”: Use the “Up” or “Down” arrow buttons on your radio to scroll through the settings menu options. Continue pressing until you find the “FOB PROG” (Fob Program) option displayed.
-
Initiate Programming: Once “FOB PROG” is highlighted, press the “DISP” button again to select it. The radio display should now show “PUSH FOB”.
-
Activate Key Fob: Immediately take your key fob and simultaneously press and hold both the “Lock” and “Unlock” buttons. Keep holding them for about 15 seconds, or until you hear the car chime. The chime indicates successful programming of the key fob.
-
Program Additional Fobs (If Needed): If you have more key fobs to program, quickly repeat steps 4, 5, and 6 for each additional fob.
-
Exit Programming Mode: To exit the programming mode, use the “Up” or “Down” arrow buttons on the radio again to scroll through the settings until you find the “Exit” command. Press the “DISP” button to select “Exit”. You should hear another chime, confirming that you have exited the programming mode.
Method 2: Key Fob Programming with a Tech2 Scan Tool
If you have access to a Tech2 scan tool, this method offers a more direct and potentially quicker programming process. This method requires a scan tool to interface with your vehicle’s computer system.
Important Note: When using a scan tool, remember that all key fobs you want to work with your 2002 Impala must be programmed in a single session. Starting the programming sequence will erase any previously programmed key fobs. You can program up to four key fobs in total. Ensure you are not near other vehicles in keyless entry programming mode to avoid accidentally programming your fob to the wrong car.
-
Connect the Scan Tool: Install and connect your Tech2 scan tool to your 2002 Chevy Impala’s diagnostic port.
-
Navigate to Key Fob Programming: Use the Tech2 scan tool to navigate through the menus. Typically, you’ll go to: Vehicle Control System -> Computer Integrating System -> Module Setup -> BCM (Body Control Module) -> Program Key Fobs. Menu names may slightly vary based on your specific scan tool software version.
-
Start Programming: Once you’ve reached the “Program Key Fobs” menu, select or press the “START” soft key on the Tech2 scan tool to begin the programming sequence.
-
Activate Key Fob for Scan Tool Recognition: Take the key fob you wish to program. Simultaneously press and hold the “LOCK” and “UNLOCK” buttons on the fob. Hold them down for 5 to 10 seconds.
-
Confirm Programming on Scan Tool: After holding the buttons, the Tech2 scan tool should indicate that the transmitter (key fob) is programmed. Follow the on-screen prompts on the scan tool.
-
Repeat for Additional Fobs: If you have more key fobs to program, repeat steps 4 and 5 for each additional key fob, up to a maximum of four.
-
Disconnect and Verify: Once you have programmed all desired key fobs, remove the Tech2 scan tool from your Impala. Test each key fob to ensure it correctly operates the door locks and other remote functions of your 2002 Chevy Impala.
By following either of these methods, you should be able to successfully program your 2002 Chevy Impala key fobs and regain full remote access to your vehicle. Choose the method that best suits your available tools and enjoy the convenience of your keyless entry system!
