Xterra tr3.0 Error 5 displayed when key is installed.

Quoting from XTERRA on website

The E5 Error is specific to the TR2000e and the TR3000e treadmills.
The error code triggers when an object is detected by the folding sensors on the underside of the treadmill. The folding sensors look like small trapezoids: two on the back and two on the front. Make sure there are no foreign objects underneath the treadmill. If no objects are present, inspect the sensors for damage. If the problem persists, please contact customer service.

The power up test sequence has detected a key in the operated condition. The power up test
sequence is performed every time the unit is turned on (powered up). This test is performed
because a permanently stuck key will inhibit the correct operation of the unit.
Possible Causes
1. A key on the display housing is permanently stuck in the operated condition.
2. One of the upper PCA's keypad interface chips has failed.
3. Liquid (perhaps perspiration) is present on the surface of a touch sensitive display.
Possible Remedies
1. Remove the keypad connector cable from the upper PCA. Restart the power up sequence, if
the ERROR 5 is no longer present, the keypad is the cause. The keypad is typically part of
the display housing. Replace the display housing to correct the problem.
2. Remove the keypad connector cable from the upper PCA. Restart the power up sequence, if
the ERROR 5 is still present, the upper PCA is the cause. Replace the upper PCA to correct
this problem. Most upper PCA's are provided without software. Therefore, the software (chip)
must be removed from the upper PCA being replaced and re-installed on the replacement
upper PCA.
3. Wipe the surface of the touch sensitive display clean of all liquid. Restart the power up
sequence, if the ERROR 5 is no longer present, the liquid was the cause.
