For once, the tin foil worked... - VK2CSW - 22-05-2018
Ok, so it might not have been a tin foil hat but it almost feels the same...
(And yes I do get why it *may* have helped.)

I had the same effect when parked in the CH2 Mt Coot-tha TV transmitter site here in Brisbane some years ago, earlyish after keyless access was available on Holdens..
I had to disable the vehicle security system to get it started and away from the site - fortunately that model had an additional key supplied that allowed for that function. That was the only place it ever occurred with that vehicle.

Quoting from the ABC article:
"A spokeswoman from Telstra said it appeared that in very few cases, some car key remotes struggled to connect with the car's receiver, so close to the powerful satellites."

There is one place right beside a local pub where I have found my car key remote struggles to unlock/lock the car. Must be some sort of device like a security system or wifi ??? which puts out a strong interferring signal.

I'd change pubs or parking spots...

"SouthGate News are reporting that motor car remotes on inappropriate 433.920 MHz frequency caused malfunction. Dozens of people have been locked out of their cars in the central business district of Invercargill New Zealand because car remotes malfunctioned in the presence of nearby radio signals.
Dozens of car owners turned up to motor dealerships reporting that their car remotes had been malfunctioning. They were unable to lock or unlock their cars and some were even unable to start the vehicles with their car remotes.
Ministry of Business, Innovation and Employments Radio Spectrum Management said it was contacted by Invercargill Police who said there was a significant number of people getting replacement batteries for car remotes because they were not working.
An RSM Compliance Officer provided advice to police on what frequency it was likely to be and a police technician tracked it to a legitimate repeater on top of the Menzies Building.
A search of the radio frequency license register shows amateur radio operator ZL4DE holds the licence on behalf of amateurs to transmit on 434.050 MHz. Amateurs have primary use of the frequency range 433.05 to 434.92 MHz.
Remote controls, such as those in car door remotes, operate within the Short Range Device Notice and have secondary use of the SAME frequency range 433.050 to 434.920 MHz. So BOTH parties are legally allowed to transmit on the frequency.
The repeater is currently off while ZL4DE, the license holder works with RSM to find a solution.
