Robbed the dealer!
Had a few little things to do on the 02 525 last week. Dead key remote operation and a flopping left read quarter window shade. Called the stealer and found out they are very proud of these two parts. The shade is $210 and the key is $170. I removed the shade and found the plastic that holds the roller at the bottom had broken off. Small amount of Rhino glue and all is well.$210 saved!!! Did some research on the key and found some info on replacing the non serviceable battery. Cut it open and pried the battery out and replaced with a Duracell off the shelf battery. Rhino glued it back together, recoded it and bang $170 saved! Did read several posts that the key battery recharges through the ignition. Cant see how that is possible as there is no connection from the printed circuit board to the metal key. its just a battery like any other remote except BMW doesn't want you to open it up and replace the battery, they want you to buy a whole key. Now I have to find something fun to spend the money I saved on!
