Who can help me with programing a remote control for my '99 Buick Park Avenue Ultra? I have instructions but they say "close door and locks will lock". That does not happen, doors lock only when shifter is moved to "R" or "D" and the only way to get locked is to push lock button or move shifter to gear. Then nothing happens when I attempt the programing. Any suggestions. I am about to go to dealer but they want $50. Thanks. buc59
