When working with electronics, it's important to choose a tool that's ESD-safe to avoid accidental damage to the device. The regular black nylon spudger or a plastic opening tool should be used whenever possible.

Insert the tip of a plastic opening tool or spudger into the the middle groove along the edge of the device.

Insert another opening tool into the groove to hold the front plate up as you separate both plates on all sides. Use multiple opening tools to keep plates separated if necessary.
