How to replace the battery in a Tile.
Tile Mate RT-11001-EU Pro Style Bluetooth Tracker is used in this video.
This applies to Pro, Sport, or Style Trackers.

Note: No need for Scotch Double Sided Tape. I forgot to cut that part out of video.
Only tools I used were:
1. Flat Head Screw Driver
2. Letter Opener
3. Guitar Pick
