I didn't know remote start wasn't an option on every escalade?
If you're looking at a 2008, then it should have the newer key fob (black, rectangular design with a brushed aluminum look at the bottom where the key ring goes) with the Cadillac logo on the back. Remote start should be the second button from the top, right underneath the lock/unlock buttons. And yes, it should be like a 3/4 circle with an arrow on one end. Hope this helps.lol, you might be right. It's the top button on the remote? symbol like a circle?
FWIW, the owner said it did not have remote start. They haven't had it long so they might not have known or got a replacement key without it?
I'm not sure, they won't come off their price so it likely doesn't matter.
