Programming Guide for 2004 Lexus RX330 Keyless Entry Remote Fob

Important Notice: These steps program only the remote functions (lock/unlock/trunk) of your keyless entry remote. The ignition key chip (immobilizer) requires professional programming with specialized diagnostic equipment and is not covered in this guide.

Programming Procedure:

  • Step 1: Initial Setup Ensure the driver’s door is open and unlocked. All other doors must be closed. The key should be out of the ignition.
  • Step 2: Begin Key Insertions Within 5 seconds, perform the following: A. Insert the key into the ignition (do not turn it) and then remove it. B. Repeat the insertion and removal once more.
  • Step 3: Door Sequence Within 40 seconds, perform the following steps: A. Close then open the driver’s door. B. Close then open the driver’s door again. C. Insert the key into the ignition (do not turn it) and then remove it.
  • Step 4: Enter Programming Mode Within 40 seconds, perform the next sequence: A. Close then open the driver’s door. B. Close then open the driver’s door again. C. Insert the key into the ignition and leave it in. D. Close the driver’s door. E. Turn the ignition to ON (do not start the engine), then back to OFF. F. Remove the key from the ignition.
  • Step 5: Confirm Entry into Programming Mode Within 3 seconds, the power door locks should cycle (lock then unlock) automatically. If they do not, repeat the process from Step 1.
  • Step 6: Program Remote(s) Within 40 seconds of the locks cycling: A. Press and hold the LOCK and UNLOCK buttons on the remote simultaneously for 1.5 seconds. B. Immediately after, press and hold the LOCK button alone for 2 seconds. C. The door locks should lock then unlock once to confirm successful programming. If the locks cycle twice, the remote was not accepted—repeat steps A and B. D. Repeat steps A–C for each additional remote.
  • Step 7: Exit Programming Mode Open the driver’s door to complete the programming process.

Note on Ignition Key Programming:

  • These steps do not program the transponder chip inside the key head. If you need to start the engine with a new key, it must be programmed using professional tools by a qualified technician.
