just measure the diameter of the socket on treadmill and order a magnetic safety treadmill key.
Can get them on ebay but you would need to check the diameter of the sold key matches by contacting seller via ebay messaging.

Everything is messed up Trying to correct will only drive you insane
Do a clean install

Mine has the same error, have you found a fix?

i RECOMMEND that you wait until the arrival for your parts. In electronic many times, the PROM or ROM, etc not coming for to do the same thing as the old chip .tHEY HAVE discrepance. By that reason it better wait. Otherwise you must have some conflicts. However you can restore to the factory if you can do it,meanwhile the part arrive you
God bless you

1_ reset the machine, disconnect the machine.
2) test the magnet, the key is magnet, test for attraction or repulsion with the magnet from your refrigerator, if do not pass the test replace the magnet.
3) replace and go and buy in homedepot for little price!

God bless you

Error Code: Replace Safety Key (SAFE)
Meaning: Safety key is not recognize
Diagnostic: Replace safety key
If problem persist replace upper display board
you should also try cleaning the area where you insert the key magnetic

P2104 Throttle Actuator Control System - Forced Idle
P2107 Throttle Actuator Control Module Processor
P2110 Throttle Actuator Control System - Forced Limited RPM
P2111 Throttle Actuator Control System - Stuck Open
P2112 Throttle Actuator Control System - Stuck Closed

Seems like Throttle Actuator is the problem.

Good luck on this repair.

I had the same problem, however the treadmill remained in 'safe out' status even when the Safety pull pin was correctly inserted.
The cause of my fault was that one of the kids decided to insert a wrist watch into the round hole located on the control panel's lower cover. In doing so this unplugged the cable connector for the magnetic switch which operates the 'safe out' function, from the main circuit board. The repair was quick and easy, i turned the power off, removed the bottom cover from the control panel and simply plugged the magnetic switch back into the main circuit board and all was back to normal.

Doing a firmware upgrade is the BEST way to recover from Safe Mode. A remote may go into safe mode itself for a variety of reasons.

However, if the remote fails to communicate with the PC when it is stuck in Safe Mode, please try the following.

1. Remove the batteries from the remote & check for any stuck buttons especially the Power button that may be causing the remote to stay in this state.
2. If it still will not apply firmware to get out of safe mode, then still without batteries hold down the #2 button while plugging into USB, and it should exit Safe Mode, and say something similar to 'Firmware Upgrade Success'. Even though it says this, still perform the Firmware upgrade since it was stuck in Safe Mode to begin with.

Hope this helps
