I am having a problem with the keys for my new (to me) 05 convertible. Most of the time it starts and runs good. But on a couple of occasitions it has acted very strange, starting up, but not idling. It will die unless I push the gas petal a little. All the gauges shut down and it won't hardly move in gear. It has throw at least 6 different trouble codes, some of which I'm told are related to this system. The last time this happened was last night. Today it is running good so far.
Would having another key made fix this problem? Is there an bypass on this so I can just start without the security system?
