Key-less entry for a car?

Question

I am looking to buy a used car. I would really like to have the key-less entry already on the car, but if it isn't, is it possible to add it? How much would it cost?

Thanks for you input.

They do sell kits for keyless entry.  You can also have an aftermarket alarm installed that will also work as a keyless entry.  I would guess about $200 for everything would be pretty close.
