Before detailing the different alternatives available to you, here is a short intro to explain the role and functions of the immobilizer in your Lexus GS. This electronic element appeared 30 years ago and aims to prevent the theft of your Lexus GS. Indeed, thanks to a transponder and an antenna (coil) included in the key, and, a immobilisation control box included in the ECU and a reception antenna on the neiman, your Lexus GS will go each time you place the key in the ignition, it checks that the code emitted by your key is actually the one expected by your immobilization box.

Indeed, with your vehicle you should have a spare key (which you should try and which should start your Lexus GS), but if you don’t have it you should at least have the “code card”, it contains the start code. Thanks to this code, you will still be able to start your vehicle by entering it manually. To do this, turn on the ignition, use your centralized button to enter the digits, several quick presses (example: 2 for digit 2) then a stop of one and a half seconds to confirm the digit and resume, repeat the process until you have entered the entire code.
