Is there any charge in your car battery

The AAA roadside service offers a pre-paid locksmith that will drive to your location and try to unlock it. If you or a passenger (that is, someone riding with you) in your car has an AAA membership, they can call the toll free number for assistance in obtaining road side assistance, or even a tow, if it becomes necessary to have it towed to a dealer for service.

It only has one switch to lock and unlock both or all rite seeing how u dont say what model if so when that switch goes i believe it controls all

Might have a seat switch to prevent access if windows are down. climb into drivers start car roll up windows open door or unlock it

How to adjust door locks and locate the central locking button. NOTE: If your vehicle is equipped with Comfort Access you can unlock all doors by grabbing the front passenger door handle regardless if you have "Driver's Door" as your setting. Also, some vehicles have Comfort Access sensors integrated into all door handles(i.e. X5) while some will only have the front passenger doors (i.e. 3 series)
