No it is standard on ex and dx
Yes, just got to the Honda website (www.honda.com, then go to OwnerLink) and you can search for accessories specific to your vehicle. The keyless entry system for the 2003 Honda Civic LX coupe costs about $250 without installation; it's $350 installed. The accessories are available for purchase through the Honda online store as well.
I have a 1998 2 door Honda civic and mine doesn't have keyless entry or an anti theft system installed, you can buy an anti theft system and install it, but they can be expensive
No it is not. It's a dealer installed add on. It is standard on the EX but not the LX. If you want it for the 97 Civic LX then you have to buy the transmitter that fits in the cut out part of the stock radio. It's available from Honda dealerships. The installation is a moderate to advanced procedure.
It was an option that was available. Some have it and some don't.
