Hack VBA Protection Code???

Hi
I have been called in by a client who had a db app put together (not very well). The original developers simply are doing nothing and the client is in despair. They have asked me to see if I can both correct the original bugs and also develop the database on.
The history is one of many unanswered phone calls and emails with the occasional promise that never gets anywhere. We spoke to the developer today who said they couldn't give the access code and then spoke to the other part of the duo who said he didn't have the code but would see if he can talk it out of the developer.
The client is a charity and like doing things the right way so I think that they will have played fair with the developer but it hasn't been reciprocated.
In exploring what they have I have been blocked by a password when I try to get into the VBA.
Is there any way to crack into this?
It would be helpful to know so that if the promised password does not materialise (and they were not holding their breath) do I tell them it is a no-hoper, or might I be able to work through?
The only alternative would appear to be to start from scratch but I suspect that would be financially too painful for them.

There is nothing earth shattering in what it does - even if it worked properly - and it is a small FE/BE database. I have full access to the BE but need to get into the code behind forms and modules to see where it is going wrong.

Any help or pointers would be most appreciated. I recognise the ethical issues but also sympathise with a client who has been shafted.
Best wishes
