1999 Chevy Venture 6 cyl Front Wheel Drive Automatic

I just got my van out the transmission shop yesterday and when I put it into drive my doors no longer lock automatically and when I use the keypad to lock and unlock the doors the horn no longer beeps and the lights no longer flash what do I need to do?
