Mobile electronics installer checking in here. This is a fascinating thread; I have a little information and a lot of comments.
Directed Electronics, Incorporated (DEI), maker of what is probably the the biggest-selling remote car starter in our industry, used to make a product called CarCom that would do the job; it also required a monthly fee. If you read about halfway down this www.carsound.com post, you’ll see that CarCom is no longer made. Other folks there also hint that it would be possible to use some other telematics (satellite tracking) system and build your own interface.
Audiovox, another popular brand (which I install), made a similar device called URL=http://www.carjunky.com/online_car_information/cars_trucks_motorcycles_safety_news/newnews/fcjt.shtml]POSSE. I’m pretty sure it’s been discontinued, though.
New cars equipped with OnStar have a nifty feature: If you’ve locked your keys inside, they can send a satellite signal for the car to unlock its doors. A smart installer could set your car up so that the remote starter will come on when the doors unlock, and then it could re-lock them just a second afterward for security. But I rather doubt the OnStar people will be happy when you’re calling them every day at 4:50 PM for “lockout assistance.”
If you ever talk to that guy again, see if you can any more information, please.
This is a great feature; I wish it was more common. Some early Nineties Corvettes had it from the factory. Also, a fairly new company called Powerlock offers such a system.
handy, I don’t have any cites to directly answer your question. I’ve heard that in some locales it’s illegal to leave your keys in the car—but under remote start, the keys are removed, the shifter won’t come out of Park, and the steering wheel can’t be turned—one would still have to go through the usual car-theft procedures to drive the car away, roll it down a hill into a crowd; etcetera. I will admit, though, that many rest stops and truck depots post signs limiting diesel-engine idle time to five minutes.
Thanks for the interesting link. The aftermarket has had a monopoly on remote starters for a long time now; I’m surprised it’s taken the OEMs this long to react. Remote start installs are a huge chunk of my income, probably 90% of it in this season, and this’ll mean a major change. But my industry has always survived by bringing new products to market faster than the OEMs until they catch up, and mobile video seems to be getting stronger and stronger. I can’t wait to see what’s next.
Every remote starter I’ve seen has its own timer. DEI units run for 12 minutes, but can be programmed for 24. Audiovox offers 5, 10, 15, or 20. Even without making the unit work from a pager, you might simply activate your ordinary remote by accident-----in any event, the car will shut off again when the time expires.
Now, back to the original project at hand…
I like the project that Debaser linked to, but I don’t think one needs to go to the trouble of opening up the remote control and connecting wires to it. Most (but not all) remote starters also have an activation input—if the activation input sees a ground, the remote starter is activated—the device could simply be set up to send -12 volts directly to the activation wire.
I haven’t had a pager in years, but if I remember correctly, most models light up when a new page is coming in. I’d imagine that this light is probably 1.5 volts, since it must operate off the pager’s AA battery. But all we’d need to do is take the 1.5 volts going to that light, and make it trigger a relay—the relay would be set up to ground the remote start’s activation wire. I don’t know how to set this up, but I think the idea is a good starting point.
I’ll also tell my friends at www.carsound.com about this thread; they may be able to offer more than I have. Also, the forums at www.the12volt.com are a good place to ask about automotive electrical projects.
Debaser: Sorry about the long post and all the minor hijacks. To answer your original question, it appears that CarCom and POSSE are dead, but I may be wrong. Also, you mentioned you’re in Boston. I live in Worcester and work in Middleton, and I’m always up for challenges like this. Contact me if you ever want to try this, or even just if you have any questions.
