For smart car owners w/ battery disconnect inside the car
Here's a way to lock the car for flat towing when the battery disconnect switch is installed under the dashboard. It requires 2 FOBs:
1) sit in the car's driver seat, with both doors rear gate/window closed.
2) lock the doors then open the driver-side door.
3) Follow your flat towing set up instructions - except stop when you get to using the battery disconnect switch.
4) with the 2nd FOB in hand, press the lock button. It will lock the doors - BUT - because the driver door is open it will then unlock the door after about a half second. This means that you have about a half second after pressing the lock button on the 2nd FOB to disconnect the battery using the battery disconnect switch.
5) complete your flat towing set up instructions
6) exit the car and close the driver door
If done right the car will be locked.
Why the 2nd FOB? From what I can tell, when the FOB is in the ignition switch the lock button on it is disabled, but the lock button on the FOB in your hand will still work.
Notes:
a) After locking the doors the FOB won't function after the battery is disconnected. You will need a key or a key blank to manually unlock the driver door to reenter the car.
b) If you reenter the car after the battery is disconnected, you will not be able to lock the door afterwards. You will need to perform the "After Towing" instructions and then repeat steps 1 through 6.
This is where my battery disconnect switch is located in the car.
