Car remotes on inappropriate 433.920 MHz frequency malfunction

Dozens of people have been locked out of their cars in the central
business district of Invercargill New Zealand because poorly designed
car remotes malfunctioned in the presence of nearby radio signals

An article by Dave Nicoll on The Stuff site reports:

Robbie Baxter Autos service manager Kris Milne said about a dozen car
owners turned up to the dealership on Monday reporting that their car
remotes had been malfunctioning.

Car owners had said they were unable to lock or unlock their cars and
some were even unable to start the vehicles with their car remotes,
Milne said.

Ministry of Business, Innovation and Employment's Radio Spectrum
Management (RSM) compliance manager Fadia Mudafar 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 Daniel Erickson ZL4DE holds the licence on behalf of amateurs
to transmit on 434.050 MHz.

Mudafar said amateurs have primary use of the frequency range 433.050
to 434.920 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."

Both parties are legally allowed to transmit on the frequency.

The repeater is currently off while the license holder works with RSM
to find a solution, Mudafar said.
