Hank, It could be a bad resistor or darlington transistor in the LockZilla that's causing the excessive drain. Since it uses the same design as the stock module, you can perform Elvis' great upgrade if you can solder: ftp://dmcnews.com/pub/lockmod91.pdf Sadly, this is one of the few "design flaws" of the car. A properly working stock module will drain a battery faster then a more modern system, but still not as quick as a week (assuming the battery and charging system are fine). Hopefully Toby's new lock module will be able to prove itself as it sounds like a great alternative when it's released!
