SOURCE: The safety key has been lost can you bypass this

Anything the same size as the key inserted in the slot will work. It just activates a switch.

If I understand correct, the treadmill will not run correct unless you have the safety key in. Well yes this is correct because once the safety key is removed the treadmill will stop. If your treadmill is running extremely fast just by turning it on, you may need a new speed sensor. www.AtlantaFitnessRepair.com

SOURCE: My sportcraft tx 2.5 treadmill does not have the safety key

any round magnet that will fit in the hole will work.

SOURCE: I have lost the safety key for my Weslo treadmill

Hi I folded up a piece of paper several times to make it into a small rectanguler shape and inserted into the slot for the key and it worked.
The replacement key doesn't need to be magnet just small enough to fit the shap of the slot is fine.Mine was a Weslo cadence 1000 (bought in 2002)
