One customer gave feedback that he failed to add new keys to his two BMW cars by using
Launch X-PROG 3 Advanced Immobilizer & Key Programmer. So he asked our customer service for a solution.
Here is the detail.
I used the X-prog 3 to add a new key to my BMW 2004 CAS. But the remote didn't work or was programmed. It could only start the car. Then I also tried it on my 2011 BMW 535i CAS 4, the process went on, then got stuck and never really added the key.
Does X prog3 support add keys to 2011 CAS? Why did I try and fail on both cars? Please give me the steps so that I can try again.
