Auto or Standard? Standard is weary because you'd need a clutch bypass. Cars have had immobilizer in them for a LONG time, this isn't something new. My 01 Pathfinder had one. You can install them.
And for most remote car starters, you can't drive the car in the remote start mode, you normally have to turn off and on again with your normal key.
IMO just save yourself alot of money/hassle and start the car and let it warm up BEFORE you drive it. Just walk outside and turn it on.
