Hi   I have a storage cupboard that's in the corridor inside GAH.  I have successfully managed to leave the only key inside the cupboard when it accidently closed shut on me. It is not possible to slip a strong piece of plastic between the door jamb and the door and open it that way.  

It is a simple YALE lock ie not double barrel or anything complicated.  I understand that, before barrels are drilled out, a locksmith type person would have a Master Key or something that basically, I suppose, picks the lock.  Do we have such a person on the Estate who would be willing to try and open it for me?

Thank you and look forward to hearing from you.  Patricia
