I spent a little time researching alarm systems years ago. I decided on the Viper for my Miata. By the time I added a few of the additional modules ie:motion detection, glass break, and had it installed, it was a costly addition. Today, that same system is just right at double the cost. I have had it upgraded as better units came along. It has been a good, functional alarm system. I am considering adding the Ravelco to my car.
I have a friend who is a locksmith, he has one of those Sentry Key reading units. I asked him about the unit and it's capabilities - he said "Let me show you", so we went out to my truck and he read my chip, made me a new key, and I still to this day use it as my main key. It worked perfectly and still does. I can buy wone of these key units today on the internet, no questions asked. I was amazed just how easily a unit can be purchased.
He also has an alarm code reading unit. He can turn it on, push a couple buttons, it reads the car he is standing next to, and then he just pushes a button and the doors unlock AND the factory alarm disables simultaneously. He tells me that it is a little more difficult with aftermarket alarms, he can buy alarm company specific modules for his unit and then it all works the same as factory units. He also went on to say that pretty much all alarm companies and installers install a disable switch the same way and in the same place, no biggie. He sent me to the website that sells all this stuff, that's where he bought his, an they sell to anyone. He learned about the website from a friend that owns a tow truck who does repos.
My point I guess is that anyone can get this stuff and steal your vehicle if that is their intent. I know people who have had their vehicles stolen with Sentry Keys and Alarms in place. I also know someone with just the Ravelco unit, their door was damaged by the initial entry but whomever broke into the truck could not get it started with a screwdriver in the ignition. They had some damage, repaired, all done. Now that person has the Jimmijammers installed.
I personally am not going to spend time debating all the stuff that is now coming up in this thread. If you guys need answers to your questions, do a search regarding your questions and concerns and find out what it is you need to know. More than likely even if someone did give you the answers you are seeking, you would continue to debate regardless. Instead of seeking PROOF, try it from another angle PROVE THEM WRONG. Do your homework, make your choices, go with what trips your trigger.
