-- Posted by AcidSilence at 11:52 pm on Aug. 23, 2008 I'm giving points to whoever can help me most of first [: I just bought a treadmill from a garage sale and noticed- those muffins didn't give me the safety key! Is there anything can can be used to substitute the key? Like a card or something? [if you don't know what a safety key is; the key kind of looks like a plastic card and you put it in the designated slot. they normally have a clip you attach to your pants, shirt, etc, and if the key gets pulled out the treadmill stops.] -- Posted by inkblot at 11:53 pm on Aug. 23, 2008 You can buy a new one. -- Posted by MrJollyRancher at 11:53 pm on Aug. 23, 2008 LOL!  I have no Earthly idea! -- Posted by SovSull at 11:53 pm on Aug. 23, 2008 ask them if they have it -- Posted by Cauterize at 11:53 pm on Aug. 23, 2008 Im sure anything would work, as long as it fits through the slot. Try a credit card [ or something of lesser value ]. Get a hole puncher and put a hole through it. Attach a string to the safety hole and through the hole in the card. Put the card in your pocket. When you fly back, the card will tuck on the string and activate the safety. -- Posted by Phoenix 2008 at 11:54 pm on Aug. 23, 2008 all you need is something methal with a plastic handel that touches both conections on the inside -- Posted by zombie4life at 11:56 pm on Aug. 23, 2008 Quote: from Cauterize at 2:53 am on Aug. 24, 2008 Im sure anything would work, as long as it fits through the slot.
