Treadmill Doctor Round Safety Key for Many Models Part Number 208603

Too early to write an informed review. All I can do is confirm that the key works on my Nordic Track .

I bought a second hand treadmill at an online auction but when I got it home; I realized this magnetic key was missing. I looked it up on Amazon and it works perfectly!

Good price for a replacement treadmill key! Was for a model purchased from sears. It was donated to our community rummage sale but didn't have a key. Found this one and ordered it with my fingers crossed hoping it would work. Started right up! I tried using a regular magnet to no avail so I guess that these keys have something special (possibly higher powered) to them. Seems interchangeable with a few other brands.

I'd misplaced the original safety key for my Smooth Fitness 9.2P (same as the 9.2AB, but programmable) treadmill, and had been using a heavy (yet strong enough) magnet to run, but it would occasionally fall off, causing an abrupt stop. I ordered this - lightweight, yet extremely strong - round magnet safety key and was elated to find it works perfectly! Recommend highly!

My toddler took my original safe key and it was a lost cause. But this one worked perfect and was reasonably priced!

This safety key works on my Smooth Fitness 5.65S treadmill.It is a perfect replacement for Safety Key Part No. 565S-229. Original parts are priced at $23.50 each plus $10.00 shippingDimensions:Inner magnet diameter = 3/8"Outer ring diameter (raised red plastic) = 1"Exterior shell diameter = 1.25"The depth from the exterior to the magnet = 1/8"

Bought several from several suppliers. All worked out well - Here's a tip; don't let your pre-teen grandkids use the treadmill key and you won't have to replace it.

Exactly like the original that mysteriously disappeared and was never seen again!
