Bowflex TC5300 Treadmill won't start: is the safety key the problem?
- LLindsay SuttonAug 21, 2025
If your Bowflex Treadmill won't start, the safety key could indeed be the issue. Ensure the safety key is properly plugged into the magnetic safety key location on the display. If it is, the magnet itself might be faulty. Try another magnet, like a refrigerator magnet, to see if the treadmill starts. If it does, you'll need to replace the safety key.
