I still dont understand whats wrong with putting a key in a door to unlock it.
Also, there was something sticky with the door lock. If I used the key instead of the fob, sometimes the anti-theft system would not disarm and the only way I found to disarm it was to use the fob to turn that alarm off. Grrrr. Fobs lasted about 3 years and cost $100 to replace/reprogram.
My current car (a Miata) has a key only to unlock the door in the event of a dead battery. It has a pushbutton instead of the traditional ignition key, so the key is pretty useless outside of a dead battery.
All remote unlock is doing is adding an unnecessary insecure remote layer on top of that for convenience.
