Many customers at a small town grocery store in Alberta had trouble unlocking their cars, while others had their car alarms going off mysteriously, since early January. According to the CBC, after trial-and-error of turning off electricity to nearby buildings and calling in the federal government for assistance, the source of the interference has been traced back to "faulty consumer electronic equipment stuck in transmit mode".
The story of the original mystery can be found here.
Key fobs that suddenly won't unlock vehicles. Cars that won't start. Alarms that go off for no reason and can't be quieted. Something mysterious is thwarting drivers outside a grocery store in the small Alberta town of Carstairs — and it's sparking all kinds of theories.
The problems have been happening for weeks in the parking lot outside the Westview Co-op grocery store in Carstairs, a town of about 4,000 about 60 kilometres north of Calgary.

Remote keyless system (RKS):
Widely used in automobiles, an RKS performs the functions of a standard car key without physical contact. When within a few yards of the car, pressing a button on the remote can lock or unlock the doors, and may perform other functions. A remote keyless system can include both a remote keyless entry system (RKE), which unlocks the doors, and a remote keyless ignition system (RKI), which starts the engine.

Luckily, I've never been employed in a division of a company that made those sorts of demands on me. Although, there were some that might have tried it once or twice. But, in critical system designs, most layers of management will defer to technical expertise, most of time anyway.
However, over the years I've been called in to 'fix' many failures caused by this mentality. The problem is too many companies hire people who don't even know what they don't know. And in a lot of cases, "good enough" turns out to be "not quite good enough".
There are many 'gotchas' in digital comms system design (especially wireless), and it's easy to get something that fails catastrophically if everything doesn't go smoothly. Crypto and cybersecurity is another related area where engineers unfamiliar with the field can be completely unaware of potential 'dangers' of a naive design/implementation.
