Does your cash drawer refuse to open, even when turning the key?
This is a rare issue, but luckily there is an easy fix.
IF YOUR CASH DRAWER OPENS WHEN TURNING THE KEY, DO NOT FOLLOW THESE STEPS.
See picture below.
Unscrew all 8 screws from the bottom of the cash drawer that are circled.
Then, lift out the bottom, and slide out and remove the cash tray and then the drawer.
Replace the bottom and the screws.
Slide the drawer back in.
The drawer will then be able to be opened.
