    • Use a plastic opening tool to release tabs that hold the front panel and back panel together. There are three tabs on each side of the device that need to separate for the device to open.

    • The use of a plastic opening tool is recommended to avoid damaging the remote. Use stronger tools as a last resort.

    • Remove the four 6mm Phillips #0 screws from the battery case.

    • The battery is still connected to the device via wiring. To free the battery completely, remove the dark plastic piece from the slot with the plastic opening tool. Slowly rotate the dark plastic piece and the battery clockwise until then can be removed from underneath the small circuit board with the USB port.

    • Removing the dark plastic piece from the motherboard takes some patience, as the remote is designed so that the battery will not dislocate under extreme conditions. The small circuit board with the USB port remains connected to the motherboard by six 10 mm pins.

A bit dissapointed with Logitech’s “throw the remote away when the battery dies” instructions on their site. However, this guide was easy and means I have a functioning remote again (only 18 months old!). Many thanks for the guide.

Step 6 (disassembly and re-assembly) Only thing to point out is that the PCB on the bottom of the battery holder twists into the holder (small plastic holding feature). This is important to get proper alignment of the Micro-USB connector). When removing the battery holder make sure the PCB pops out of the snap that is on the opposite side from the screw that holds the Micro-USB connector. This avoids putting too much strain on the leads of that PCB.

Wish I read the comments before I did the work - came close to snapping the leads. To anyone trying this, the battery holder is not attached to that small pcb but rather there are small notches that hold the battery case in place. Knowing that will allow you to apply the right pressure in the right places to move it away from the PCB.
