89070-48020 full replacement key.
Compatible with 1999, 2000, 2001, 2002, 2003 RX300
Key includes remote fob with battery and 4C transmitter chip.
Ships within 2 business days via USPS.
If you are interested we also have a programming service for the RX300 that programs a key to your ECU.
Our key is fully tested.
The 4C chips that are installed in most keys on the market now are defective either missing coding or unreadable.
We use these same keys for our programming services we offer and test each 4C chip in every key.
If you’ve tried to program a key in the past using your master key and it didn’t work, it’s most likely the chip was defective, even if you purchased a new key.
This key will need to be manually programmed if you have lost your master key. The key will have to be programmed directly to the ECU. Check out our programming service if you have lost all keys to your vehicle.
Don’t hesitate to reach out if you have any other questions, we are always here to help!
