Secure Takeover for 4th generation Lexus GS?

I have been looking into remote starts for my car, but what I have seen so far is that no manufacturers seem to have an option for secure Takeover on my 2013 GS450h. Do any of you guys know of a product that supports this? I don't like the idea of having to shut down the car and then start it again any time I remote start it.

It is possible but not recommended. There are two reasons that all bypass module manufactures make their solutions shutdown the remote started engine as soon as a door is opened. The main reason was that the vehicles computer gets upset and might set some codes. The other reason is that it is possible to remote start the vehicle, unlock the doors and then get in and drive away without the Smart-Key. If you realize you don't have the Smart-Key with you after you park and exit the vehicle, you are SOL. Anyway here is a link to the early Fortin solution that uses an EVO-ALL and an INT-SL+ bypass module : http://fortin.ca/download/3431/evo-all_ig_reg_bi_toy_gs350-gs460-2009-2012_pts_a_3431.pdf Not positive that it will work on your 2013 GS450h. The guide only lists up to 2012 and I've never tried it.Soldering is fun!

2012 is the previous generation, which I also owned and installed a remote start on. That previous generation did allow for secure takeover and I got it working perfectly with an EVO-ALL. However, the the new generation GS, I don't know if it is possible, and I sure hope someone has a trick to make it work because I'm going to miss that feature if I can't have it.
