I just bought an 05 Montego. The keyless entry code card is missing. Doesanyone know where I can find that?

Talk to a dealer. They will be able to tell you where it''s mounted on the vehicle (usually a not too visible location inside the vehicle and behind a panel and can very wildly between models).

Found it. This year/model it is on the back of the fuse box under the steering wheel. You''ll need a mirror and a flexible back to see it.
