re: Keyless entry remote "dead zone"

my garage door openers all quit at the same time. i changed batteries and nothing worked except getting close to the opener itself.

i realized that i had changed out all of the 12v interior lights in my travel trailer to LED, and was still working on it in the driveway. when i turned off the lights, the garage door openers worked just fine.

tldr: LED lights emit signals that interfere with radio waves
