I have a 2005 Vibe base model with the "Keyless Entry" system. When I picked up the car today it worked fine at the dealer. The locks unlockedat 30 feet but after I drove the car home neither of the two key fobs would work. Thought the problem might be due to the fact that the person showing me the car's features opened and closed the rear hatch. After I opened and closed the rear hatch the key fobs now locked and unlocked the car. Went out this evening and the key fob opened and locked the doors once. Then I went to unlock the car and the doors did not unlock. Unlocked the doors with the key and drove to a second location. the key fob locked the doors. Came beck later and the fob would not unlock the doors. When I returned home the fob did not work but about 20 minutes later I tried the fob a second time and now the doors would lock and unlock. I am going back to the dealer but thought there might be something I am missing in the logic used to control the keyless entry system. Would appreciate any thoughts.
