Sorry for the delay responding to your answer. You were right on the money. The dealer confirms that it's probably the key, so I ordered one. It'll be here next weekend. They say I'll need to get it activated, so we'll do that at the same time. Thanks again for the help,

Don

PS - What goes wrong with the key, is it the metal or something inside the remote control?
