In October 2013 the <strong><a href=\"http:\/\/mybroadband.co.za\/news\/security\/88275-criminals-using-jammers-to-steal-your-car-police-warning.html\">Eastern Cape police warned that criminals<\/a><\/strong> were targeting motorists by overriding vehicle remote locking systems.<\/p>\n<p>The recent rise in crime where car remote jamming is suspected means that an overview of how this crime works, and what can be done about it, is valuable.<\/p>\n<p>The video below provides a real-life example of how criminals use car remote jamming to steal possessions.<\/p>\n<p><iframe loading=\"lazy\" src=\"https:\/\/www.youtube.com\/embed\/kPHbCa_FiCI\" width=\"600\" height=\"338\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<h3 class=\"my-4\">How car remote jamming works<\/h3>\n<p>Fouche Burgers from Business Against Crime SA explained that criminals can block, or jam, the locking signals of remote locking devices on vehicles.<\/p>\n<p>Most modern remote controls use rolling-code technology, which means that the code command cannot be copied or cloned.<\/p>\n<p>However, because most modern remote controls work with radio waves that use an allocated radio frequency, they are vulnerable.<\/p>\n<p>The use of this specific radio frequency is prescribed by\u00a0Icasa.<\/p>\n<p>Most remote controls, including those for motor vehicles, gate, and garage automation operate on a frequency of 433MHz. Understandably, this frequency has become very busy.<\/p>\n<p>When a remote control button is pressed, it sends a message (command) on the allocated frequency to a receiver (in the vehicle) to perform an action: lock or unlock the vehicle.<\/p>\n<p>At the other end, the receiver is \u201clistening\u201d for a specific message that it can interpret to perform a required action.<\/p>\n<p>When a button of another remote is pressed in close proximity, the receiver receives (hears) two messages simultaneously.<\/p>\n<p>The two messages are consequently scrambled, the receiver cannot interpret the message, and no action is initiated (the vehicle\u2019s doors are not locked).<\/p>\n<p>Remote controls operating on the same frequency can influence each other\u2019s messages if they are operated in close proximity.<\/p>\n<p>According to Outsurance, thieves often use a standard 400MHz gate or garage remote control to jam the signal sent by a car remote control.<\/p>\n<p>To make matters worse, there are \u201cprofessional\u201d jamming devices available that function on a range of frequencies and that have much higher signal power.<\/p>\n<p>These devices can influence a vehicle\u2019s remote control from a much greater distance and can even interfere with remote controls that use different frequencies and technologies.<\/p>\n<p>It should be noted\u00a0that these remote control and jamming devices cannot unlock your vehicle. They can only stop your remote control from working properly.<\/p>\n<p><strong>[Also see:<\/strong> <strong><a href=\"http:\/\/ewn.co.za\/Media\/2015\/03\/24\/The-Science-Of-Car-Jamming-Special-Report\">The science of car jamming<\/a>]<\/strong><\/p>\n<div id=\"attachment_91726\" style=\"width: 610px\" class=\"wp-caption aligncenter\"><a  data-lightbox=\"post-image\" href=\"http:\/\/businesstech.co.za\/news\/wp-content\/uploads\/2015\/06\/Car-remote-jamming-infographic.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-91726\" class=\"wp-image-91726\" src=\"http:\/\/businesstech.co.za\/news\/wp-content\/uploads\/2015\/06\/Car-remote-jamming-infographic.jpg\" alt=\"Car remote jamming infographic\" width=\"600\" height=\"2252\" srcset=\"https:\/\/businesstech.co.za\/news\/wp-content\/uploads\/2015\/06\/Car-remote-jamming-infographic.jpg 800w, https:\/\/businesstech.co.za\/news\/wp-content\/uploads\/2015\/06\/Car-remote-jamming-infographic-80x300.jpg 80w, https:\/\/businesstech.co.za\/news\/wp-content\/uploads\/2015\/06\/Car-remote-jamming-infographic-273x1024.jpg 273w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><\/a><p id=\"caption-attachment-91726\" class=\"wp-caption-text\">Car remote jamming infographic<\/p><\/div>\n<h3 class=\"my-4\">What you can do about car remote jamming<\/h3>\n<p>Burgers and Kingdom Electronics suggest the following steps to prevent the jamming of remote controls.<\/p>\n<ul>\n<li>The most important rule: Make sure your car is locked before you walk away.
