I had the same thing happen to me yesterday. Today the car won't start at all and the battery is fine. Locks continue to lock and unlock as if the car was possessed. Help would be most appreciated!
try disconnecting the battery
Try disconnecting the alternator, could be the diode pack
Assuming the battery is good, you have a short somewhere in the electrical system that is draining your battery. You can confirm this by disconnecting the battery each time it is parked. If that solves problem, a short is confirmed. A professional has the devices to locate the site of the short.
Battery has a dead cell, need to replace battery
most times ther is a short in the circut. maeanig that a wire in the circut that is supposed to be hot at all times, even with engine off, is connecting to ground(body or frame of car) and battery is constantly draining.
If your battery is good and you know your car is draining it then yes, disconnecting your battery from your car will keep your battery charged for much longer than 3 days. Your battery should stay charged way longer than 3 days in normal conditions being hooked up to your car. You should get it checked out and figure out what is draining your battery so fast.

Then either something is on draining the battery or the battery has a dead cell draining all the rest and must be replaced.
Yes, with an OBD II reader. Disconnecting the battery won't reset it.
By disconnecting the battery.
A short will not drain the battery it will blow a fuse. It may be the battery has a dead cell, or some light is on draining the battery. It can also be a stuck relay.
