Default Bypass immobilizer

2006 Lexus IS 250. Has fault 2799 related to immobilizer. Is there any way to bypass the immobilizer?

B2799 results in a communication problem between the key and the smart key ecu. It can be as simple as the key losing its programming (have it reprogrammed at a locksmith, or the dealer), wiring issues (usually rats chewing on them), or a failing smart key ecu (which will require a replacement). I don't believe this car can be bypassed like older cars can, there's a reason many remote start solutions for this car don't work properly.
