The place I got the quote from said they would need the security card
that I got from the dealer (credit card size) and also a valet key.
The way he described it would work is I would leave the car running,
get out of the car, close the door and turn off the car from the remote
transmitter. That way it ensures the car is in neutral when I turn it
back on with the remote transmitter. I will have to check about
whether or not it bypassing the security, but I seem to remember him
saying it would work with the security system (hence the use of the
security card and valet key, I assume).

Does this make any sense? I want to make sure I'm not getting screwed,
plus I would want to make sure they have a warranty on the install,
etc.

Thanks.
