Have to go to Cadillac to program tire sensors, WHY? Just doesn't make sense.

What is your question?

put new tires and 1 sensor replaced, Wheel Works can not program the sensors. Tried 2 other sources, Chev. And local mechanic and no one could get into the mode to program. Only Cadillac has propriety soft ware to get in! That's CRAP! Some one should figure out how to hack into the xlr system so at least the local repair shops can serve their customers and not have to go to the dealer. To me this is a hold-up and does not let us have a fair chance to get our maintenance done by our own trusted mechanics. My garage just spent $20'000 to upgrade his Snap-on machine so he could service my XLR and it will now do Cadillac but not the XLR. I have to take it to the dealer so I can have 2 TPSM'S programmed. It; going to cost $$

What makes this problem better or worse?

none

How long has your 2009 Cadillac XLR had this problem?
