Yes, my key (2008 GM) is just a button activated radio transmitter (315 Mhz) with no proximity sensor on the vehicle side. Once the key is inserted in the ignition, however, the pass-key system does verify the chip code.
I would just as soon get rid of all the electronic stuff and go back to mechanical fuel injection and no ecm, personally.
