Having to press the button in the central glove box has become an annoyance. Has anyone installed a different solution, I assume its only an electric control?
It's just an electric push switch. You could, if you wanted, run wires from the switch terminals to anywhere else in the cabin - e.g. the plastic surround around the gears.
you can just hold the lock/unlock button on the fob - although when looking at a car this weekend without the Daihatsu fob I couldn't quite figure that out.
