<p>R3S11B temperature sensor readout failed again yesterday, the
reading was unstable. We have a bad history with this sensor in
2017, 2018, and now. I suspect intermittent connection on the
patch panel. I disabled it for now from the interlock to prevent
the trips.<br />

Managed to remove the broken key from the cRIO interlock chassis and used Velcro to attach the key to the box instead of leaving them plugged in (see attached image); the same key works in both of the switches. There is also a spare key located inside the chassis itself.
Updated to the latest stable firmware (which matches what Hall D is using) on all the MPOD controllers: MPOD-BL-2.2439.0 & MPODmaster-2.1.4298.0
Somehow got the hybrid temperature working again, but all we did is un/re-plug several times and measure with a DMM. So nothing obvious was wrong with it.
