I just wanted to share my experience today.

Car has had died on me recently so after reading posts on here, I decided to go and get it done.

Went to sears, they would not install the battery on a 06 x5 because they had issues. So I decided to purchase the diehard and do it myself. Well after installing the battery, the car would crank but would not start. I put the old battery back after that.

So after returning the battery at sears, went to the dealer. After talking with the foreman, he checked my vin and he confirmed that the car needed to be reprogrammed. It was $229 for battery and $205 for labor. Well I had no choice so I decided to go ahead and do it only to find our there were no appointments available for the day.

So I just bought the battery and was going to take to Indy shop who was going to do it for $100, but also could not guarantee it would be done today.

So I tried again in a parking lot by putting the new bmw battery and what do you know, car starts. Aldo don't see any issues. Should I take this car to get it programmed or am I ok?
