Locker Key Lost

You rented a locker at the university library for the semester and have lost the key. Your laptop charger and notes are inside, and you have an assignment due tomorrow. Speak to the library service desk staff: explain what happened, apologise, and ask how quickly the locker can be opened and what the replacement fee is.

Hi, sorry to bother you. I rented locker 214 on level two for the semester, and I'm afraid I've lost the key somewhere between campus and home. I've searched everywhere without luck. The problem is my laptop charger and all my lecture notes are inside, and I have an assignment due tomorrow morning. Would it be possible for someone to open it today? I'm also happy to pay whatever the replacement fee is, if you could let me know the amount. Thanks so much for your help.
