Frequently Asked Questions
1. How do I verify if my original Lexus key is a "G Board"?
You must open your keyless entry remote case and inspect the internal circuit board. It should be stamped with the letter "G" or the number "0020". If it has "AG", this remote will not work.
2. Why is professional programming required for this push-to-start key?
Lexus smart proximity remote systems use encrypted 8A chips that must be synchronized via the vehicle's OBD2 port using specialized diagnostic tools to ensure security.
3. Does it include the battery and emergency blade?
Yes. This replacement key includes a pre-installed CR2032 lithium battery and an uncut LXP90 high-security blade ready for cutting.
⚠️ Critical Fitment Notice
This proximity key is strictly for G-Board (0020) systems. It is NOT interchangeable with the "AG" board version despite sharing the same FCC ID. Verify your board ID before ordering. Professional programming is mandatory.
