That's all good putting a link that will tell you how to pick a lock, but and this is the big but if to OP is working for local council then they will have a I.T. Department that will stet up all comp and will not give all the keys to the user .so all he has to do is ask for spare key from said department and then unlock them

Any keys like this could more likely be held by the council audit department.

But why are you doing it surely it will be down to the IT department not electrical?

For when you absolutely must cut through the cable, laptop, desk and floor! Overkill, if it isn't working you're not using enough!
