Ok let me be the one decenting voice here. (comming from a mechanic) I hate these things, yes it is a nice feature but be prepaired for trouble down the road. They can cause starting issues or lack of starting issues. I have also been working under the hood, doing eletrical problems and have had them start. The quality of install has alot to do with the functionality of the system but, I have removed more of them than I have installed. I will also tell you that if I get hurt as a result of one of these systems malfunctioning I will own you and the installer. This has been proven here in Va already.
If it is too much of an inconvience to walk out to start your car a few mins. before you leave the house you may want to look at your priorities.
This is all my opinion but I would recomend not installing one.
