Lost or need a spare key fob for your 2004 Lexus RX330? Don’t want to pay dealership prices for a replacement and programming? You’re in luck! Programming a new key fob for your 2004 Lexus RX330 can be done relatively easily at home with the right instructions. This guide will walk you through the step-by-step procedures for programming both the transponder chip and the remote functions of your 2004 Lexus Rx330 Key Fob, saving you time and money.
Programming Your 2004 Lexus RX330 Transponder Key
The transponder chip is essential for starting your Lexus RX330. It’s a security feature that communicates with your car’s immobilizer system. Here’s how to program it:
Step-by-Step Transponder Programming Procedure
- Ensure all doors are closed. This is crucial for the system to enter programming mode correctly.
- Insert your existing, programmed master Toyota key into the ignition cylinder and remove it four times in quick succession. On the fifth insertion, leave the master key in the ignition cylinder. This action signals to the car that you intend to program a new key.
- Open and close the driver’s side door six times. Make sure to fully open and close the door each time. This further confirms your intention to enter programming mode.
- Remove the master key from the ignition cylinder. At this point, your car should be ready to learn a new transponder code.
- Verify entry into programming mode. Look at the security indicator light on your information display. It should be illuminated solid, not blinking. This solid light confirms that your 2004 Lexus RX330 has successfully entered transponder key programming mode.
- Insert the new, unprogrammed chip key into the ignition cylinder. This is the key you are trying to program to your vehicle.
- Wait for the security light to blink. The security light will now begin to blink. Allow it to blink for approximately 60 seconds. This is the system programming the new transponder chip.
- Observe the security light. After about 60 seconds, the security light will turn off. This indicates that the new key has been successfully programmed to the immobilizer system of your 2004 Lexus RX330.
- Remove the new key from the ignition cylinder. The programming process for the transponder chip is now complete.
- Test the new key. Insert the newly programmed key into the ignition cylinder. The security indicator light on the information display should disappear when the key is properly inserted. This confirms that the new key can deactivate the anti-theft system and start your vehicle.
Programming Your 2004 Lexus RX330 Remote
Once the transponder chip is programmed, you’ll want to program the remote functions (lock, unlock, panic) of your new 2004 Lexus RX330 key fob. Here’s how:
Step-by-Step Remote Programming Procedure
- Start with the key removed from the ignition. Ensure the key is out of the ignition cylinder. Unlock and open the driver’s door. Make sure all other doors are closed during this process.
- Perform key insertion and removal cycle twice within 5 seconds. Insert the key into the ignition (do NOT turn it) and immediately pull it out. Repeat this insert and remove action one more time within 5 seconds. This quick key cycling initiates the remote programming sequence.
- Execute door close and open cycle twice within 40 seconds. Close, then open the driver’s door. Repeat this close and open action one more time within 40 seconds. This door cycling further prepares the system for remote programming.
- Perform another door close and open cycle and key insertion within 40 seconds. Close, then open the driver’s door two more times. After the second door opening, insert the key into the ignition cylinder and leave it in the ignition (do NOT turn it). Then, close the driver’s door.
- Cycle the ignition and remove the key. Turn the ignition to the “ON” position, then immediately back to the “OFF” position (Do NOT start or crank the engine). Remove the key from the ignition cylinder.
- Check for door lock cycle. Within 3 seconds of removing the key, the power door locks should automatically lock and then unlock. This lock and unlock cycle indicates that your 2004 Lexus RX330 has successfully entered remote programming mode. If the door locks do not cycle, return to step 1 and repeat the procedure.
- Program the remote. Within 40 seconds of the door lock cycle:
- A. Press and hold both the lock and unlock buttons on the remote simultaneously for about 1.5 seconds.
- B. Immediately after releasing both buttons, press and hold the lock button by itself. Within 10 seconds of performing these button presses, the door locks should lock and then unlock once. This single lock/unlock cycle confirms successful programming of the remote. If the door locks cycle twice, it indicates the remote was not accepted. In this case, repeat steps A and B in step 6 again.
- Repeat steps A and B for each additional remote you wish to program. You can program multiple remotes using this procedure.
- Exit programming mode. Open the driver’s door to exit the remote programming mode.
By following these steps, you should be able to successfully program a new key fob for your 2004 Lexus RX330. Enjoy the convenience of your new key!
