I found that neither of my cars would program with the instructions in the handbook, had to fudge it a bit.

 

Thanks for sharing,, on my 2011 XJL I've tried "everything" in the manual to get it to work no luck and will not sync up, I cant get that fast flashing light. I have a year old house with a brand new Liftermaster do you think this would still need that same repeater you posted?.. I had an 08 cadillac CTS that I needed one of those things too so at least I'm familiar.. Is there a number I can call that you can recommend just to be sure that I actually need one??? TY

 

I had to install a bridge to get my cars to work with my Liftmaster, once it they connected fine. You might try calling Liftmaster, they used to have decent support (haven't called them in years though).

 

Liftmaster is the brand I went for that needed the bridge. Found it on Amazon for much less than from liftmaster.

 

Are there different ones to choose or just 1?.. Have the link???
