Car Thief

You surely know that we have a wiki service where different people ask questions about the technologies they are interested in and how to protect themselves from those technologies. A couple of days ago I was asked a question about how to protect your car alarm from code grabbing devices. The question was answered but I thought that it will be better to dedicate the whole blog post to this topic because we consider it to be really urgent and relative. Also those code grabbing devices spread wider and wider these days because it is the easiest way to steal an auto or just open it and steal everything that is inside.

Such a tactic is the most common. Thieves open the vehicle with such a device and then they act fast, because they don’t know whether you have a trinket with a feedback. They just take anything they want from your car and then lock it up with that code grabbing device. Then they just go and if they are lucky you will not even spot that you was robbed for an hour or two. Such thieves usually “work” on the parking lots near big shopping malls or other trade centers.  So be careful if you are parking a car there!

Now we will pay attention to the devices that made all those things possible. You should know that your trinket exchanges signals with a receiver of your car alarm really frequently. Those signals are carried by the radio waves that have a specified frequency. Car alarms are using different frequencies in different countries. Basically they are 315, 433 and 868 MHz. They may vary depending on countries and manufacturers of car alarms but the most common frequency in USA is 315 MHz. So that’s why thieves and car hijackers know what frequencies to use.

Code Grabber

The next thing you need to know is that that when you are locking your vehicle with your trinket it sends a signal on one of those frequencies to your vehicle’s alarm receiver with a specific code. This code tells your car to lock or to unlock the doors, trunk and hood. That code grabber act as passive receivers, when you send such a signals to a car alarm receiver code grabber reads that transmission and gets the code. The only thing left to do for thieves is to crack that code and after that they have an access to your car.

The signals send by those code grabbing devices are recognized by the car alarm’s receiver like your trinket. And that’s why car alarm reacts properly on such signals. Many people are willing to gain some protection from those devices and seeking the answers on the internet. So, we gathered all the probably working ways of protection and we will share them with you.

Code Cracking

The first way to protect your car from code grabbers is to stop using a car alarm. It is the simplest way, but your car security will be lower. So try this way if only you have nothing else to do. You should know that many people stop using car alarms when they find out that with those they can be hijacked even easier. You may also use different alternative car control systems.

The second way to protect your car is to use a modern multifrequency car alarm, that uses different frequencies all the time and it is really hard for thieves to intercept those signals. The other modern types of alarms generate different codes for every time you lock and unlock your vehicle so even if thieves will get the code and crack it they will achieve nothing. Such protected car alarms are really popular these days and they are rather expensive but they will provide you protection. can provide you one more option though. That option is cheaper and it will not involve the replacement of your car alarm. The option is in using a remote control jamming device. The only problem there you can face is to detect the frequency that your trinket is broadcasting on in order to pick a proper jamming device.  We can offer devices for specified frequencies like 315 MHz or others but we really recommend you to use a universal remote control jammer. That device combines jamming of all common remote controls frequencies.

That device will block the frequencies remote controls use and leave any chances for thieves to get into your vehicle. So make your choice and protect your property.
