Well, this topic is moving right along I see.
I was in visiting my dealership today to pick up some touch up paint. I asked the parts guy about a couple things. Now, keep in mind anything I say here is hear say. Anyway, I asked about the difference in the GRAY key vrs the BLACK key with built in entry/panic - he said "nothing, both are sentry chipped, the 2006's all have sentry chips". I asked him what it would cost to ADD the factory alarm module, to include the blinking red light stuff, horn beeping,etc - he said "$169. 00 installed". It will work off the black key w/built in fob buttons. Then I asked him if there were any other means of security or anti-theft I could install - he said "JimmiJammers and the Ravelco". My dealership used to install the Ravelco units, now a local alarm shop does them for them, well not actually for them as they get no kickback or otherwise, they just send people there to get them installed. So, he kind of gave me an un-biased opinion regarding what the dealership recommends. He actually went into quite the sales pitch about the Ravelco units. He told me that he knows several people who have them, have had break-ins, but their vehicles were not stolen, tore up some, but not stolen. He has one on his truck, took me out and showed me.
Since I have no vested interest, I am not selling them, actually getting one installed tomorrow, I figure what I have learned is worth telling others. So, if you are so inclined to consider a Ravelco unit as I have, and if you are further inclined to have one installed - good for you in attempting to protect your truck/your investment.
As far as the other information I posted regarding the stuff necessary to read codes, etc. I have first-hand seen it used, it does work as I described it, it was not on some old GM system, it was ON MY TRUCK that the demo was done - for my benefit by a friend. Anyone can either take or leave what I have said and seen, it makes NO difference to me one way or another BUT it might make some difference to you somewhere down the line. I have not posted the website regarding this stuff BECAUSE I would not want to contribute to someone of the 'thief' caliber getting their hands on and using this equipment. If I can search the web and find it SO CAN YOU, and you can do it as part of your search for enlightenment regarding what can happen to your vehicle that you might want to find a way to sidestep.
Maybe none of the sentry key trucks were 'driven off' maybe they were jerked onto a flatbed, I have NO IDEA because I was not there to see someone's truck stolen AND IF I would have been there to watch, based on how one's word is taken here, it would have been regarded as hear say anyway. To me that remark is just double-talk and side-stepping the REAL ISSUE which has to do with the BENEFIT of the Ravelco discussion and it's contribution to anti-theft as a whole. So, you can either take my word on what I have seen and tried to communicate, albeit not using the standard lingo which might give more creedence. By the way, I DO understand how the sentry key works and serves it's end purpose in our vehicles, I am just not good at articulating that stuff.
Thanks for your time reading my lengthy post. It will be the last one in this topic.
