hitrack is an unknown quantity at this point
I'm a wee paranoid of this. So the FOB battery dies....

You use the key to open door, I assume this deactivates the alarm????

You touch the fob to the start button, in essence just use the fob to push the button???

All is good you can drive to home???

Has anyone for S's & Giggles taken the battery out of the fob and just tried this????
