This problem started several months ago. It became worse till the ignition key jammed and became hard to turn to start the engine then, last week, the key would not turn at all. I called my dealership and was asked to bring it in to them but was hesitant to. I went on to my computer, did a search, and saw several complaints on the 2005 Odyssey experiencing this problems and the cost that they were quoted was astronomical. I then looked up a reliable locksmith, that worked on ignition switch repairs, located in my city and they were able to repair it. The tumblers, actual one (1), had becomes worn and that caused the switch to freeze. I do remember a recall on earlier models of Honda for having this similar type of situation. I did find out during this visit with this locksmith that a local dealer, not mine, would bring their Hondas to them, that had been brought in to their Honda service department, and had this locksmith company do the actual repairs.
