Safety key magnet not strong enough - Precor Treadmill 9.21 9.21s 9.25 9.21si 9.25 Replacement Motor Hood Cover

Verify the safety key is present and functioning. Most machines use a magnet and any strong magnet will be enough to close the circuit.

Most treadmills meet there demise from a faulty lower control board under the hood. It can light and be mostly functional, but still have issues. Boards are not very cheap but are very easy to install.

Make sure to take an image of the original board to copy the wire location/connections.

Boards often go bad from an array of issues, but verify the condition of the underside of the walking belt is not black and the deck is not worn. Lack of lubricant and too much friction on the belt system usually overloads the board with heat and damages the board.

Hello. In the mean time you can use a fridge magnet to get you back on the machine. You might need a strong magnet, so if the first one doesn't work keep trying.
try googling the brand of machine you have to purchase parts or try eBay under treadmill safety keys.

Magnetic drills have a safety system built into them so the motor will not run unless the magnet is on and the tool is sitting on between at least 1/8-inch and 1/4-inch steel. If your drill is sitting on enough steel you may have a problem with the sensor system inside the drill. Those problems are usually electronic parts related and, most of the time, they are R&R (Remove & Replace) method is used until you fix the problem.

search fFITNESSREPAIRPARTS.COM for a key. Otherwise any "rare erath" strong magnet should be strong enough to set the sensor off.

Sometimes they can be bypassed. If you have a thick refrigerator magnet, try passing that over they key area to see if that will unlock it. Thin business card style magnets are not strong enough. If that does not work, call the manufacturer for a replacement key, they are around $20 plus shipping.
Good luck!

Hello there. Yes you actually can use a magnet. (thats all the safety key is) It will need to be strong enough to make the switch inside the console activate. I use one from a telescoping magnet used for picking up small screws (available at the big box stores) when I dont have one on service calls.
Just to let you know a refrigerator magnet will not be strong enough!
Good Luck! Tim

you can use eny magnet, and if you need the string you can epoxy glue it to the magnet you are using

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)

The ipod uses a flash memory and it shouldnt effect it.
