Hi @ethanhunt ,
The best way (but not the quickest) is to replace the keyboard.
You can cause more problems than what you had when trying to repair keyboards.
They are not that expensive to replace.
Just search online for Dell Inspiron 15-7548 keyboard to get results for suppliers.
Here’s a link to the service manual for the laptop, taken from this webpage.
Scroll to p.57 to view the necessary pre-requisite steps and then the procedure to remove/replace the keyboard.

Did you spill soda on the keyboard? It sounds like you need to wipe out the gunk that was left behind. It's an easy enough fix, you will need to make sure the device isn't plugged in and then drain the remaining voltage buy holding down the power button.
