I experienced a weird behavior the other day in a hospital parking lot. My vehicle's key fob that I use to lock and unlock the vehicle doors wouldn't work in a hospital parking lot. But then after I left the hospital it was working normally again.

Is this some kind of RF blocking technology some hospitals may be using as a safety measure in certain locations, for example, to prevent inadvertent consumer electronics interference or criminal interference with various electronic medical equipment ? I will be going back to that hospital again and will try to park in the same spot as before to see if this problem repeats. The key fob battery is fresh, I replaced it not too long ago, since I know by experience that can cause intermittent function with a low battery.

I'm not a conspiracy theorist person, just curious to know if this is a known thing, or if any of you guys have experienced it before. I know this can be due to all sorts of faulty equipment of controllers going bad slowly resulting in intermittent failure, but I'm just curious if RF interference is common with key fobs. So far I've ruled out aliens and democratic cannibals Rf jamming operations in Papua New Guinea.

15 years ago, the Hospital emergency room in Miramar Florida clearly had one, as cell phones worked outside the sliding door, but not at all inside.

I think cellular has a long history or being blocked depending on the sensitivity or vulnerability of the area, US Military spaces being an example, particularly if nuke storage and handling are involved.

If near the Radiolgy Department, perhaps it was the lead shielding.

I would change the key fob battery just in case.

A car remote doesn't have the power to get above many random transmissions that can occur in a hospital. So, probably accidental jamming.
