Hi, everyone, I just bought a flip key of eBay and trying to program the key, searching, and tried a lot of ways, I found out below those 2 ways are working for 2004 lexus rx330

Programming Procedure for transponder

1. First, close all doors
2. Insert master Toyota key in and out of the ignition cylinder 4 times. On the 5th time leave the master key in the ignition cylinder
3. Open and close drivers side door 6 times
4. Remove the master key from the ignition cylinder.
5. Verify that security light on the information display is solid, indicating that the car successfully entered programming mode
6. Insert new chip key
7. Watch security light blinking for about 60 seconds
8. When the security light goes out, your new key is successfully programmed
9. Remove the new key from the ignition cylinder
10. And finally, verify that your new key is able to deactivate anti-theft system: security indicator light on the information display should disappear when inserting properly programmed key into the ignition cylinder
