Wanted to get a duplicate key made. The store said they could not cut a spare key because a chip inside was required. That is, the chip or sensor had to be in proximity of the car for they key to work. I don't agree (for this car).
I used the extra key that came with the car. It has no buttons and also no battery. I left the buttoned+batteried key in the house and went out to the car with the non-electronic spare key. The car started okay. The spare key has an oversized handle on it but no way to open to replace a battery.
Does this car's keys actually have a sensor or chip that prevents copies from being used to drive the car? This car does not have keyless entry. You either use the key to open the door or the buttons on the master key to activate the radio to move the solenoid. There is no Start Engine button in the dashboard. The car is started using the traditionally positioned ignition key component in the steering column.
