Yesterday's afternoon, I removed the driver door's panel to fix my speaker. I decided to check the key barrel from the inside and didn't see any mechanical linkage from the key to the rest of the locking system. It seems to be just a switch.
I've never experienced a battery so dead, that it can't operate the door lock actuators. In my late Datsun, I was able to unlock doors with battery giving 6~8 volts. In my previous tracker, the doors worked even when the car wouldn't even turn on the dim lights.
However, this Vitara is the first car I've owned with factory installed-BCM controlled power locks.
So, in the unlikely scenario you open the engine hood, raise all windows, step off the car, lock doors, remove the car battery and close the hood... are you officially f****d??
(This, unless the blessed BCM, using some kind of leftover power, unlocks a door when it detects the battery is removed).
These systems are pure evil. :devil:
