BlueTooth headset disabling remote key?
I've got an iPhone and a Motorola BT headset. For reasons not clear to me, if I have the headset and phone on my remote will not lock or unlock the doors but will work in the ignition. Doesn't make sense to me as I believe the remote key is IR and BlueTooth is RF. If I turn the head set and phone off the key works fine. Has anybody seen this? thanks.

The key is actually both RF and infrared. It uses RF to lock/unlock doors and open the trunk, and IR to open/close the windows/sunroof when you point it at the IR receiver. (The IR receiver is the little square block on the outside drivers door handle)
I have a Motorola phone and a Jawbone bluetooth headset and have not seen that problem in either of my cars. Very interesting...
Can you borrow another headset and/or phone to test it out?

Pretty strange still if the door locks do not work with the phone on the cradle, sounds more like the phone kit is confusing the CAN-bus or something.
