Unfortunately, without the additional information requested in my first/previous response, I will not be able to give you detailed advice to your question, but I will be able to give you a general answer, which I hope will be of assistance. If you are able to supply the additional information later, please do so and I will then come back to you with a more detailed answer.
Following from what you have explained, the will clearly states that the property is to be sold and the proceeds divided equally between the 4 daughters.
That is therefore what must happen. This does not give them any right of access to the property or to remove any personal items of your late mother from the property. The will is clear, they receive a share of the proceeds.
The only person entitled to keys to the property is the executor named in the will.
They are responsible for dealing with the estate, sale of house and distribution of funds.
I hope this helps answer your question.
Please come back if I can assist further.
