First, the central locking system only deadlocks when the car has been locked with the key either manually from outside the car, or with the remote buttons on the fob. So if you've left passengers or kids inside the vehicle...you should NEVER lock them inside. Not only because of the double lock feature...but because 30 seconds later, as soon as something moves inside the car, the interior motion sensor will set off the alarm...now not only are they locked inside the car...but they are going deaf from the alarm going off. Alway let remaining passengers use the central lock button to secure themselves if leaving them inside the car or push the door pins down manually (drivers door must be closed to push door pin down).

If the car has been locked using the central lock/unlock button on the center console, or if you have the auto lock @ 5 MPH enabled, or if you've manually pushed the door pins...then the car is only single locked & two pulls of the interior door handles should open the doors.

I can't think of any situation where you'd have kids in car seats and you'd lose all electrical power except in an accident...and in that case,the central locking system is designed to unlock all doors, turn on the interior lights, and turn on the emergency flashers.

In the situation you're in now...car parked in your garage/driveway...unlock the drivers door, pop the hood, connect jumper cables or a battery charger to the jump start posts in the engine bay...this will provide enough juice to unlock the vehicle. Once the double lock has been disabled...and you still don't have a good battery but still need to secure the car...you can now lock the car manually by either pushing all the door pins down manually & locking the drivers door with the key or using any door except driver's...manually push down all the door pins and exit one of those doors last. Again the driver's door won't lock while its open.

Even if you have a small battery charger that can be inserted into a cig or 12 volt outlet...this will even provide enough power to use the remote fob to unlock your doors.
