Add another to the list who has remote FOB issues after upgrading interior lights to LED. I did read this thread when it originally posted but forgot about it when I processed my SuperbrightLED purchase last week. I ordered replacements for 2 front dome, 2 spot (map) lights (btw, map bulbs don't appear to be replaceable...at least not with what was recommended), a pair for 2nd row and 2 reverse bulbs. Immediately noticed same FOB issue (NO KEY DETECTED) after install was complete.
I did this upgrade late yesterday then left early this morning for a road trip so I haven't been able to thoroughly troubleshoot but the 'flaky' FOB connection behavior that I've experienced since yesterday seems to align with what others in the thread have experienced. Maybe the higher priced LEDs from other vendors address this issues. FWIW, this is a '14 LX and I did have an iPhone in-pocket.
