How much it cost to get the keylock reprogram or have my car locks programed

What is your question?

The problems is I took my car to Suss Buick because they said the keylock worked but it needed to be reprogram to my car. They said after an hour that there was a problem and it would cost me more to find out what the was is. My problem is that when I put the car in drive all the doors unlock and they stay that way I have to manually lock them when I get out of the car.
