Something mysterious is blocking vehicle key fobs from working in a small Alberta town | CBC News

"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.

A longtime employee at the dollar store right across the street from the Co-op says it's all she hears some folks talk about when they come into her store to buy a battery for their fobs — and then discover that doesn't solve the problem.

"I've been at the dollar store almost four years," Laura Strate said, with a laugh.

"It's just bizarre. People are actually scared to go to the Co-op now because they don't know if their cars are going to start."

"Puzzled store calls in electricians — and even federal ministry

Westview Co-operative Association Carstairs says it's taking the matter very seriously"
"We joke around here in Carstairs, 'Yeah, put your tin foil hats on,'" Strate said."
 
Met a guy last year who was an IT security person for an auto insurer. Claims with the right software- he could stand in a parking lot with his laptop and access 75% of the cars that arrived within a couple of minutes. Opposite of this problem- but makes you wonder.
 
A couple of days ago, our car FOB did not work either when parked at a chain food store in Toronto.
Assumed it had something to do with the extreme cold, although it has never previously happened in cold weather.
 
Key fobs won’t work near an Alberta grocery store – and no one knows why
“Any new LED bulbs with drivers built in?” asked Brent Sharp. “I have seen garage doors that don’t open with the lights on.”

He also posed that street lights or nearby security systems could be part of the problem.
“There’s a large radio tower right behind the co-op with lots of an antenna,” suggested Paul Pgee. “That would be my first guess.”

And yes, some wondered if the mysterious issue was the work of aliens."
 
Awesome and very interesting, thanks!
"Owners of Cadillac and Lexus luxury models were especially plagued by the glitch, says David Maxson, who runs Isotrope, a Midfield, MA-based firm that specializes in radio-frequency systems.

He was hired last week to investigate the fob problem by Extenet, a company that installs cell-phone antennas on light poles. The antennas were thought to be the source of the interference, but it took Maxson less than 24 hours to trace the signal to a building on a block that housed a bar.

With the consent of the bar's owner, he determined a light-control panel used by a DJ was the source of the interference that rendered key fobs useless. The panel was designed to send out intermittent signals but somehow transmitted a continuous stream of data on the same bandwidth used by some fobs.

Key fobs trigger signals on two bandwidths: 315 mHz and 434 mHz, which in turn activate microprocessors unique to each vehicle. Only fobs operating on the former bandwidth were jammed by signals from the light-control panel, despite Federal Communications Commission regulations that require short-range devices to operate intermittently."
 

This does sound like something exactly like the problem they are having. They need to check the bars. LOL Or any nearby place that has any kind of electronic lights or other electronics. Maybe even one of the signs that have digital displays or something.

Great catch.

Someone needs to forward this link to their authorities to give them some ideas.

This part is identical to what they experienced.

"At first, car owners besieged a local hardware store in search of new batteries for their remote fobs, but replacing the batteries didn't help."

"Before you laugh, this is a legitimately weird and unexplained occurrence. It’s localized to the parking lot surrounding a local grocery store—the the Westview Co-op—in the small central Alberta town of 4,000. And it’s been going on for a few weeks now.

Some cars in the lot won’t unlock or start, while other cars’ alarm systems are set off by what could possibly be a glitch in the matrix."
"One user said that something similar happened in the small New Zealand town of Invercargill in which a local amateur radio operator was broadcasting 434.050MH—315 for North American built cars—the same frequency in which the fobs operate. Many, many others online have pointed out that most likely the issue is some sort of radio interference, but the cause of the problem is still unknown. This also happened a few years ago in Yonkers, New York, when a DJ’s light control panel sent out a frequency that interfered with key fobs."

“It's called a signal jammer. Illegal in Canada but easy to obtain,” wrote one CBC commenter. “If I were an irate customer, or a morally lacking competitor, this is something I might do to make their customers go away.”

"Another commenter on the CBC story agreed, writing, “UFO's are well known to interfere with electrical fields.”
"Aliens it is."

If anyone has ever read the fine print on some of the electronic devices you buy, you will see a note about this sort of thing.

Im reading the manual right now from my garage door opener and it says in fine print

"In order to comply with FCC rules.....yada yada yada.....this device may not cause harmful interference......yada yada...."

Ive seen these warnings before and paid no attention to them thinking everyone complies but I guess not. :)
