Lost your key fob or need to program a new one for your 2002 Chevy Blazer? Don’t worry, programming your key fob at home is easier than you might think. This guide provides straightforward, step-by-step instructions to get your key fob working quickly, saving you a trip to the dealership.
Before you begin, gather all the key fobs you plan to use with your 2002 Chevrolet Blazer. This programming procedure will erase all previously programmed remotes, so you’ll need to program all of them in one session.
Here’s how to program your 2002 Chevy Blazer key fob:
-
Prepare Your Vehicle: Ensure all doors of your Chevy Blazer are fully closed. Insert your key into the ignition, but do not turn it on yet.
-
Initiate Programming Mode: Press and hold the UNLOCK button located on the driver’s side door panel. Keep holding it throughout the next steps until instructed to release.
-
Cycle the Ignition: While holding the UNLOCK button, quickly turn the ignition key from the OFF position to the ON position and back to OFF twice in rapid succession. “ON” is the position just before you would start the engine, and “OFF” is the position where you can remove the key. Do not start the engine.
-
Release the Unlock Button: Release the UNLOCK button on the door panel. If you’ve successfully entered programming mode, the door locks will cycle, locking and then unlocking, indicating the system is ready for programming.
- Troubleshooting Tip: If the door locks cycle before you release the UNLOCK button, the programming mode has not been correctly initiated. You’ll need to repeat steps 1 through 4 again, ensuring you hold the UNLOCK button until instructed. If the locks continue to cycle prematurely, double-check that you’re following the procedure correctly. If issues persist, there might be a malfunction in your vehicle’s keyless entry system.
-
Program Your Key Fobs: Take the first key fob you want to program. Simultaneously press and hold both the LOCK and UNLOCK buttons on the key fob. Continue holding both buttons until the Chevy Blazer responds by cycling the door locks again. This might take up to 5 minutes, especially when programming a new, unprogrammed remote. A previously paired remote will usually program much faster.
-
Program Additional Remotes: If you have more key fobs to program, repeat step 5 for each additional remote immediately after the previous one is programmed.
-
Exit Programming Mode: Turn the ignition key to the ON position. This action will exit the key fob programming mode.
-
Test Your Remotes: Remove the key from the ignition and test all programmed key fobs to ensure they are working correctly with your 2002 Chevy Blazer.
By following these steps, you should be able to successfully program your 2002 Chevy Blazer key fob. If you’re still experiencing difficulties or need a replacement key fob, visit Keylessentryremotefob.com for a wide selection of key fobs and remotes for various vehicles.
