Post 2010 CX9 Door Lock

Hello Mazda world...


Every time I lock the doors, by FOB or the locking button on handle, the doors unlock then the front windows and sunroof open. Thought it might be a FOB issue so removed battery and cleaned FOBs. Nope. Thought maybe something wrong with IT so pulled positive for 1 hour and then reattached. Hoping for a BCM (Body Control Module) reset. Nope. Decide to try physical key and found that someone had jammed something into keyhole and severely damaged locking mechanism.

Could this be the cause? Is locking mechanism more than mechanical? Can not find locking mechanism part, only handle.

I'm good at jumping down rabbit holes so any advice would be appreciated.
Thanks, JorlC

Pull the door card off and disconnect the door barrel. Try locking the vehicle with the remote and see what happens.

So I pulled the door card and could see tension on the lock barrel. So I jammed a big flat tip into the key hole (tumblers already destroyed) and twisted until things were straight. Locks now working fine. Thanks for the suggestion.
