Nikon D5100 Repairability Score: 2 out of 10 (10 is easiest to repair)

The battery can be easily replaced by opening the compartment with your thumbnail.

The rear cover comes off with minimal unscrewing/desoldering (for this kind of device), allowing you to access the motherboard.

The D5100 has several wires that need to be desoldered in order to take it apart.

Approximately 4 billion screws hold the device together.

Components are very tightly packed, making it more difficult to disconnect and remove them.

For absolute safety, you need to discharge the flash capacitor, otherwise you risk accidentally killing your camera.
