How can I get an image of my newly owned 1998 Lexus GS 300 immobiliser and ignit

What is your question?

I recently bought a 1998 Lexus GS 300 that have been parked for almost 3 year and its immobiliser and the complete ignition are all gone missing from previous technicians i suppose,also red light keeps blinking. So please I need a clear image of how my 1998 Lexus GS 300 immobiliser and ignition and key fob looks like so that I can get an exact replace and begin to enjoy my ride.

What makes this problem better or worse?

Is worst because there's no immobiliser and I don't have an idea of how it looks like so as to be able to get the exact type to replace

How long has your 1998 Lexus GS300 had this problem?

After a month of purchase
