If a 60 ma drain is taking your battery down in three days, replace the battery. With the key off, there IS some drain due to the uP's in the various modules "keeping alive". I have measured mine (my car is 1,000 miles from me right now) but I can't remember what the number was.

Gone are the days of ZERO drain with the key off, cars today have micro-p's that need to be kept 'refreshed' and alarm systems that run all the time.

If you are leaving the key on (and I"m sure you are not, must be a slip of the keyboard!) then stop doing that!
