Has anyone or does anyone know if a push button start is actually doable? I have my 2005 RX330 in the shop because of the tumbler in the ignition switch quit on me this morning. While thinking about my wife's Toyota and the push button start, I thought this would be the perfect time to have it done. I don't expect to have the same thing that my wife's vehicle has i.e. Automatic door unlock. But I've been using my valet key because of the cheap plastic that the keyless entry is made of! So at the very least I'd gain using my keyless remote sensor back. Thanks in advance for any light y'all can shed on this matter.
