Check grammer (不要用翻譯網站)

"We cannot access to your office to check any water leakage as your office is unmanned and we have no key. Please inform us when you are back such that we could come to investigate the matter.

Sorry for the inconvenience so caused."

Considering you as an outsider in this scene, it is understood that you should not have key. The only reason that you cannot enter the office is that it is unmanned which is the logic behind for adding in this word in the passage.If this is established, the clause " and we have no key" can be deleted. Please correct me if this conjecture is wrong.

支票可否再重新入一次?

Could you please re-deposit the cheque to the account again?

We do not have keys to open your office door, therefore we were unable to check whether your office has a flooding problem.

Please advise when will you return to your office. We will send our staff to check the problem as soon as you are in the office.

Sorry for the inconvenience caused.
