Climb into your car with flashlight and a multimeter. With everything off and the doors shut pull one fuse at a time and put your meter across the fuse terminals with the meter set to measure amps. Then adjust the meter to measure milliamps. In this way you will be able to find out what circuit is drawing power when the key is off. Yes the door lock module does have a standby current draw of about 12 milliamps if I remember correctly. There is a modification that can reduce this to about 1 mA but I think your battery would have to be pretty bad for that amount of current to matter over a weeks time. If you need more help contact me.
