Lost or need to replace your 1999 Chevy Blazer Key Fob? Don’t worry, programming a new key fob for your 1999 Chevrolet Blazer can often be done right at home without a trip to the dealership. This guide provides you with easy-to-follow, step-by-step instructions to program your 1999 Chevy Blazer key fob, saving you time and money.
Step-by-Step Guide to Program Your 1999 Chevy Blazer Key Fob
Before you begin, ensure you have a compatible key fob for your 1999 Chevrolet Blazer. You can typically find these online or at automotive parts stores. Let’s get started with the programming process:
-
Prepare Your Vehicle: Begin by closing all the doors on your 1999 Chevy Blazer. Make sure all doors are completely shut for the programming sequence to work correctly. Insert your key into the ignition, but do not turn it on yet.
-
Initiate Programming Mode: This step is crucial for entering the programming mode. Press and HOLD the UNLOCK button located on the driver’s side door panel. Keep holding this button down throughout the next steps until instructed to release it.
-
Cycle the Ignition: While holding the UNLOCK button, quickly turn the ignition key from the OFF position to the ON position, and then back to OFF, twice in rapid succession. The “ON” position is just before you would start the engine, and “OFF” is where you can remove the key. Do not start the engine.
-
Release the Unlock Button: After cycling the ignition twice, RELEASE the UNLOCK button on the door. If you have successfully entered programming mode, the door locks will cycle from lock to unlock automatically. This lock cycling is your confirmation that the vehicle is ready to learn the new key fob.

Troubleshooting Tip: If the door locks cycle before you release the UNLOCK button, it indicates that the programming mode was not correctly initiated. In this case, you will need to repeat the process from step one, paying close attention to the timing and button presses. If the locks continuously cycle prematurely, double-check that you are following the steps precisely, or there might be an issue with your Blazer’s keyless entry system.
-
Program the First Key Fob: Now, take the first key fob you want to program for your 1999 Chevy Blazer. Press and hold down both the LOCK and UNLOCK buttons simultaneously on the key fob. Continue holding both buttons until the vehicle responds by cycling the door locks again. It’s important to note that when programming a brand new, unprogrammed key fob, this step might take up to 5 minutes for the vehicle to recognize it. If you are reprogramming a key fob that was previously paired with the vehicle, the response will be much faster.
-
Program Additional Key Fobs (Optional): If you have additional key fobs (new or existing) that you want to program for your 1999 Chevy Blazer, repeat step 5 for each additional key fob. This is the time to program all the remotes you want to use with your vehicle.
-
Exit Programming Mode: To finalize the programming and exit programming mode, simply turn the ignition key to the ON position. You do not need to start the engine, just turn the key to the “ON” position as you would before starting.
-
Test Your Key Fobs: Programming is now complete! Remove the key from the ignition and test all of your programmed key fobs to ensure they are working correctly. Test all buttons – LOCK, UNLOCK, and any other function buttons your key fob may have – to confirm proper operation.
By following these straightforward steps, you should be able to successfully program your 1999 Chevy Blazer key fob. Enjoy the convenience of your working remote!
