I was told I need to drop them off so the shop can determine what they need to get fixed.
How long will it take for my laptop and extra keyboard to be serviced and how much does it usually cost? I need my laptop and keyboard.
Ask the place you dropped it off. Each shop is different - it could take longer at one vs another depending on the shop and how busy they are, if they send it elsewhere for work, etc.
You might need to wait for them to assess it - but they should be able to tell you how long you should hear back from them on the assessment.
