Programming Your 2006 Lexus GS300 Key Fob: DIY Instructions
This programming sequence is designed for adding a new remote or reprogramming an existing one due to malfunction or replacement. Ensure you have your new key fob and are ready to follow each step precisely.
-
Preparation is Key: Begin with the driver’s door open and all other doors closed. Make sure the key is removed from the ignition switch.
-
Initiate the Sequence: Insert the key into the ignition switch, and then immediately remove it. This action signals the start of the programming process.
-
Door Lock Switch Activation (Part 1): Locate the vehicle’s door lock control switch on the driver’s side door panel. Press the “LOCK” and “UNLOCK” buttons alternately, a total of 5 times, at approximately 1-second intervals. This rhythmic pressing is crucial for entering programming mode.
-
Open and Close Driver’s Door: Close the driver’s door and then reopen it. This step further prepares the vehicle to receive the new key fob information.
-
Door Lock Switch Activation (Part 2): Repeat the door lock switch sequence. Press the “LOCK” and “UNLOCK” buttons alternately 5 more times at 1-second intervals, just as you did in step 3.
-
Ignition Key Insertion: Insert the key back into the ignition switch.
-
Select Programming Mode: This step determines whether you are adding a key, erasing old keys, or checking the number of registered keys.
- Turn the ignition switch to the “ON” position and then immediately back to “OFF” once to program a new key remote transmitter code while keeping the original codes.
- Turn the ignition switch “ON” and “OFF” twice to program a new key remote transmitter code and erase any previously stored codes. If you are replacing a lost key, this is the recommended mode for security.
- Turn the ignition switch “ON” and “OFF” three times to check how many key remote transmitters are currently registered to your vehicle.
- Turn the ignition switch “ON” and “OFF” five times to erase all registered key codes. This option is useful if you are unsure who might have access to old keys.
-
Confirmation and Key Registration: Remove the key from the ignition switch. At this point, the system should automatically lock and unlock the vehicle doors a certain number of times to confirm the selected mode. It will lock/unlock once, twice, or five times depending on the mode chosen in step 7. It may also lock/unlock slowly one to four times to indicate the number of key remote transmitters currently registered.
-
Synchronize Remote Buttons: Immediately press and release both the “LOCK” and “UNLOCK” buttons on your new key fob simultaneously.
-
Finalize Programming: Press and hold any button on the key remote transmitter for at least 1 second. This action registers the key fob with your 2006 Lexus GS300.
-
Programming Additional Remotes (If Needed): If you have more key fobs to program, repeat step 9 and 10 for each additional remote within 40 seconds. Remember that a maximum of 4 key remote transmitters can be programmed to your Lexus GS300.
-
Exit Programming Mode: To exit the programming mode, simply close the driver’s door or insert the ignition key.

Important Notes:
- Year Verification: While these instructions are generally for 1998-2005 Lexus GS300 models and are likely applicable to the 2006 model, always double-check your vehicle’s owner’s manual for the most accurate procedure. Lexus models can have variations, and confirming the correct steps for your specific 2006 GS300 is recommended.
- Diagnostic Programming: It’s important to note that for some later Lexus GS models (specifically 2007-2009 mentioned in some resources), key fob programming might require specialized diagnostic equipment. If these DIY instructions do not work for your 2006 Lexus GS300, it is possible that your specific model year or trim requires professional programming.
- Professional Assistance: If you encounter difficulties or are unsure about any step, it’s always best to consult a professional automotive locksmith specializing in Lexus vehicles or your local Lexus dealership. They have the expertise and tools to program your key fob correctly.
By following these detailed steps, you should be able to program your 2006 Lexus GS300 key fob successfully. This DIY approach can be a convenient way to regain access to keyless entry and vehicle security features.
