Seems the closest military base there is in Calgary around 30 km away. And Edmonton 240 km away. Those are the two areas with a military base nearby. Must be something local, with the RCMP then.

NOT A MYSTERY. In my area many times an aircraft carrier sails into port in Bremerton the key fobs fail to work. The car dealers are inundated with complaints. Finally someone remembers the Navy is responsible and calls them on it. They say they have no idea. The FCC gets involved and does an "investigation" for "unauthorized frequency use." The Navy says they have no idea, sorry. Then the fobs start working again.
The reason this happens is because some screw-up Chief forgot to turn off the electronic countermeasures so they are still spewing out interference on the low voltage frequencies. Had this happen to me at work. Drive home and the fob worked fine. Around here we treat the whole thing as a bit of a joke. Obviously no aircraft carriers where you are, but somebody has their countermeasures on. That's the issue.

A broadband RF scanner and some triangulation should sort this out fairly easily. Sounds the sort of bastardry hackers & phrackers used to get up to for jollies.
Key fobs work on 300 to 433 Mhz.
On top of frequency hopping.
What Project said or some dumb snip with an over powered ham radio set up.

Using Occam's razor, it must be hakkerz with one of
Or maybe a bunch of them. Or something more powerful.
The simplest explanation is the signal is being jammed. Maybe some kid who works at the co-op installed a "wireless router"-looking device alongside the existing wifi routers in the store. Who would even notice? Chances are, nobody. Because in-store employees and managers rarely have a clue when it comes to hardware in the store, and if nothing is wrong with the wi-fi, why would they even look there?
Or it could be an adjacent building, but that would increase the risk of detection. For some haqr kid working a sh** job at low wages, what could be more fun than watching all the clueless customers complain and discuss with clueless managers?

I wonder if they have a high level of magnetics in the ground.
There was some seismic activity in the west coast not long ago.
Perhaps that could of shifted something just enough to allow the magnetic field in the ground interfere with the electronics.
But I’m not an electrical engineer so I don’t know the amount of magnetics it would take to cause such an issue.
I do remember when I was a teenager that I had my Marshall guitar amp close to my tv, and the screen changed colours on the side next to the speakers, when it got to close to the tv.
It’s odd that it hasn’t been noticed before
In 2009 residents in an area of St Ouen [Jersey, Channel Islands] dubbed The Millais Triangle were driven to distraction by a low-frequency humming noise. During the same year, they suddenly discovered that their car key fobs had stopped working. Neither mystery has ever been solved.
