I just got my 6 on Saturday. When I locked it the lights would flash and if I pressed lock a second time it'd honk. When I unlock the lights flash too. Well yesterday I dropped it off at the dealer to get some stuff done to it (rust proofing, etc). When I picked it up, the lights wouldn't flash any more when I locked it (wouldn't honk either). It still flashes when I unlock. I'm thinking maybe there is some setting they accidentally made that turned this off??? The car still locks, but I like the lights to flash so I know it is locked. How can I get this to work again???
