Do you have to get the bcm flashed or reprogrmed every time the battery goes dad on a 2006 buck lucern
All systems should reset after disconnecting and reconnecting a good charged battery. However, before going any further you should remove the dead battery, have it checked and either replace it or charge it out of the vehicle. Then, install it and see if that works. If not, you probably will have to replace the BCM. Jump starting a dead battery is a very bad idea unless it is done very carefully, and even then, it can cause damage to modules.

That is not necessarily correct-if the car sits all the time, parasitic drain on the battery will eventually kill even a new battery. Telling someone that a car has to be driven 1000 miles a month to maintain the battery is not a solution-if you don't drive alot, get a trickle charger ($good one is $30, one that works can be found for $10) that you can plug in and keep hooked up to the battery to keep it fresh. Another way is to get a solar panel charger (1 1/2 watt, about $20 at Harbor Freight) and put the panel on the dashboard, and the other end into the cigarette lighter socket in the dashboard. A third solution is to buy a deep cycle battery (Optima) that can be fully drained hundreds of times yet will recover and work properly-these are expensive ($175), but out perform conventional batteries that die if fully discharged a few times. You could also install a remote starter and periodically start the car, letting it run for 15 minutes-about $200

A good mechanic with all the special tools can do it in an hour. Releasing and reinstalling the serpentine belt is what the special tool is needed for. the rest is simple socket wrenches to get the mounting bolts out.
