How much would it be to have a keyless entry unit installed in my Honda Accord?

My car is a 2002 Honda Accord LX and I plan to have a Honda dealership install it.|||Do it yourself for $49.95 per remote plus about $10 shipping. Keyless remote entry was standard on the 2002 Accord LX and you can program it in yourself. I have used this company a few times and found them to be reliable.
