The MacBook Pro 13" with Function Keys earns a 2 out of 10 on our repairability scale (10 is the easiest to repair):

The trackpad can be removed without first removing the battery.

Proprietary pentalobe screws continue to make opening the device unnecessarily difficult.

The battery assembly is entirely, and very solidly, glued into the case, thus complicating replacement.

The RAM is soldered to the logic board. Pay for the upgrade now, or be stuck with 8 GB forever. There is no chance of upgrade.

The proprietary PCIe SSD still isn't a standard drive. Cross your fingers for future compatible drives; for now, you're stuck with what you've got.
