This is for the newer immo system (AAAA). Starting with 2020 and newer cars, Lexus switched to the newer system. On the original key, you can check Page 4 line of data with a transponder tester. This key is correct if P4 line of data is AAAA. If your P4 line of data is A9A9, this key will not work for you.
