Hi Just gone to insert key into lock and it was very stiff and will not turn on. Both keys are the same so I presume it is not the keys. Tried a bit of release fluid on the keys before insertion but that not help either. Has anyone else had the same problem and if so what did you do to overcome it. Didn't help any that the window and roof were open and it started to pour down and no manual closers that I could see. Couldn't believe it!!
