Talking with the Tech who installed mine yesterday, he noted that when replacing earlier modules, as he did on mine, he had to REPROGRAM both keys with BUDS otherwise the ignition wouldn't work; however, lately reprogramming the keys is no longer required. He pointed out that something had been changed but he didn't know what.

Hopefully, those of us who got DESS modules recently, and those about to get them, will not have any further failures.

Might it have been some sort of BUDS update? Time will tell.
