Can their frequencies be hacked easily allowing someone to open your car and disarm your car alarm?|||Scanner..
A thief will scan all parking cars and try to open the cars with fixed or hopping codes in 10 m range and the 3 billion hopping code can be tried in 10 minutes.
If the Remote Keyless Entry (RKE) system under attack doesn't use extra encryption and authentication algorithm, this traditional try and error approach is quite useful in hacking most of the RKE (Remote Keyless Entry) systems.|||I highly suggest you do not buy, unknown off brand name of some cheap pile of crap of an alarm. a decent car alarm is not cheap, a good one runs a litte over 300 bucks, installed ,and will include key features such as remote start and door lock,and unlock, also it would be upgradeable, so if you choose to add other features, you can without replacing the entire system. and if you go talk to a local stereo outlet near your house, find someone who knows enough not to sell you some cheap chinese crap alarm for a hundred bucks, that is basically junk even if brand new. Find out the top three names of alarm manufacturers who use good electronics, not cheap shoddy knock offs that break in six months to a year and focus on buying one of those three, if you insist on buying an alarm off ebay. I would pay the 300 plus, first of all it gets a professional install, you have any problems and at least someone has the know how to trouble shoot, and fix the problem.
There are questions on here every week, HELP CAR ALARM I BOUGHT WONT WORK, AND I CANT START MY CAR! its your money do what makes sense to you!|||Odd answers.
A car alarm is, at best, a deterrent. As all cars now have ignition immobilisers, car theft is done 99% of the time by someone pinching your keys, then your car. No alarm will prevent this, and in fact the best deterrents were the old Citroen %26amp; Peugeot 'keypad' immobilisers - a friend in the scrap business told me that if they didn't have the code for one, the cost %26amp; complexity of getting around them made it uneconomical to do anything other than strip the cars for parts.
I work in electronics, and this involves both fitting, and more commonly removing, factory %26amp; aftermarket alarm systems when they invariably go wrong. I've fitted some of the cheapy central locking %26amp; alarm kits off Ebay, and (touch wood) never, ever had a problem or a unit fail - certainly not in the last ten years. I do, however, regularly remove or replace 'quality alarm systems regularly - yesterday, both a VW factory unit in a Golf %26amp; a Thatcham certified alarm in a Suzuki.
In short, yes, they're 'hackable', but I assume you're not fitting a cheap alarm to a 拢50,000 car. And as above, if someone wants your car they can trailer it away in under 3 minutes, or if it's what's in the car they're after, then no alarm stops a window being broken. As a deterrent, a cheap alarm is easily as good as one costing several hundred.|||It's not so much a problem of them being hacked and disarmed. It's more of a problem that you don't know who owned it before you and what they've done to it.
The system may not be secure because the previous "owner" will know the codes to disable it. In fact, it may not actually operate in the way the expect and so parts of the system could be disabled before you even fit it. You wouldn't know about that until someone breaks into your car - and it's too late then!
With national gangs of car thieves around, do you really want to put yourself at risk just to save some money by not buying from a reputable dealer?
Cheapskates who skimp on safety and security are more at risk than those who don't fit any devices at all - because they will give you a false sense of security, which is a bad thing.|||Probably as safe as the ones you would buy in your local car accessories shop.
