I had a LiftMaster 8550 installed yesterday. Much to my surprise, my 2011 Yukon Denali XL will not program to open it. Neither will my wife's MDX. Apparently, LiftMaster is using a new security mechanism that most cars are not yet compatible with.
I was also surprised to learn that GM switched from HomeLink to Lear Car2U - I don't know when they switched, but I do know from looking at OEM part websites, that the 2007-2012 Car2U units haven't changed (was hoping for an updated one in the 2012s).
Lear does make a repeater which will allow our trucks to open these new systems, but it's an additional $35 and requires the use of another plug in the garage. I ultimately will have to mount a power strip since I am running out of outlets. Its just another pain in the arse.
BTW, Chamberlin owns LiftMaster, which also sells to Sears, so just be aware if you buy a new garage door opener that it won't work out of the box.
