I cringe at the thought of the responses I'm likely to get to this question and fully expect to have a "Duh!" moment, but here goes. I just bought an '09 Genny 3.8 with nav, and I'm curious why I get an incessant dinging sound when I turn the car off and open the door. I've concluded it has it has something to do with the key as it does not happen when the smart key is in the smart key holder. It seems like its a warning to remove the key from the vehicle but as I understand it, the vehicle cannot be locked with the key inside so I'm curious why I need to be warned. I seldom use the smart key holder and find this extremely annoying. Thoughts? Thanks in advance.
