Rather interesting question here. I've got a friend with a customer who's wanting to use some sort of passive starter kill device. He previously used the headlight switch, but his vehicle was still stolen and cleaned out. I've suggested the passive method shown on the site that allows a start without any visible signs (such as horn, lights, etc.), but we haven't settled on that yet. We've also considered the cigarette lighter....it would make a rather inconspicuous passive start switch. Ideally, if the lighter is plugged in (and heating up), it would allow the vehicle to start. If the lighter isn't pushed in, the vehicle won't start. Additionally, for added security (such as at the mall, etc.), he can take the cigarette lighter with him and the vehicle won't start at all until it's replaced. Anyone got a clue how to make this happen and still have the cigarette lighter function? Thanks in advance!!

Thanks, draasch, for the suggestion. While that would work, I don't know if he can convince the customer to purchase another unit....especially since there is no alarm in this vehicle to begin with. He can't even get the customer to agree to that expenditure. The cigarette lighter was chosen for his preferred switch because of it's ability to be removed and be incredibly inconspicuous. He's considered hiding another pushbutton, but is reluctant to do that because of the fact that this customer frequently has other people riding in the vehicle and doesn't want them to be able to foil the starter kill. Good idea, though. Thanks!

the parts runs around $15. it's a small price to pay for a starter disable unit without an alarm...... ------------- Good Luck

I'd use the horn as the starter... When the key is turned to "start" the vehicle, a relay is thrown and pressing the horn starts the vehicle. It was done in my other vehicle and resting your hand "innocently" fooled my friends in the vehicle so it's a fast, easy quick fix. There's more options such as using the brake and horn ring combo. It's doable. Sean ------------- Emergency Vehicle Technician

So how do you wire the relay, and if you can disable the kill.(at mechanics or car wash) I want something thats somewhat new and the cigarette seems new to me. I do not like the horn because after you do it, people get wise to it. I plan on installing my alarm in two weeks so if you guys can help a brother out.......

In all honesty, If this guy "customer" cares about his belongings he would go out and spend the money for a good alarm. Trying to find all these ways without spending a dime is a hard way to go. Obviously he dosent care enough to pay a little one time then to pay alot over and over. I would tell him your not responsable for anything that happens in the near future.

After my old T/A was stolen and my $1,200 stereo was yanked from it....along with countless other things.. I found myself wondering.....why didn't I ever bother to get an alarm? Although in this nieghborhood, I doubt it would have made much difference...but my car would have still been there! The cig lighter is a good idea....if you're lighting a cigarette every time, or if you're certain no-one sees you. I would imagine that a relay with it's coil in series with the lighter power might work. Try it, it won't matter if it's on the positive or negative wire, as long as 85 and 86 are connected with respect to the current flow. On my car now, I have a hand-me down stereo and I sometimes sneak the starter relay out if I feel uncomfortable about where I'm parking.

The cigarette lighter sounds like a novel idea, but you must also think of the fact that they are usually on the right hand side of the wheel, as is the key, ergo you are going to have both hands on the same side of the wheel at some point, since all lighters go to s**t at some point. then the problem of using the lighter that much, the element will be getting a hell of a workout and burn out pretty soon, then you are up the proverbial creek, unless you have a glove box full of them. The other problem with passive starter kills is that if you have the time and opportunity, you can just short the starter under the hood, and presto, your ride just performed a Copperfield. Your friend honestly needs to convince his customer of the need for some form of security system in conjunction with the starter kill. Depending on the kind of car, I have a long list of very useful starter kills that I would rather not post out in public, since my customers are trusting their cars to my honesty and secrecy. Let me know and maybe I can hook you up with a good solution.

You could make it so that when you push the cig lighter in, it grounds.. thus switching on a relay. I would cut out a little piece out of the cig lighter socket, Put a wire there connected to the relay. So when you have the cig lighter there, it connect the ground and the relay together.
wire
____, | ,_____ cig socket
-------------------- |
cig lighter | |
-------------------- |
the cig lighter will act as a metal to contact the wire with the cig socket (the metal that surrounds the cig lighter)

OK. I've been trying to keep up with all of this...unfortunately, I was out on the road with work all last week and couldn't post a reply. Since then, the topic has been really well visited. A couple of things are of note here, though...
First, the customer wasn't interested as much in protecting the CONTENTS of the vehicle, especially since he didn't have a large audio investment to protect or anything else of value. He's only interested in protecting the VEHICLE. He just got it back for the second time after being stolen and joyridden. Nothing except some rather extensive interior damage and a little minor exterior damage. The problem is that the individual I posted this for was the one trying to help him prevent this from happening again, and the customer was very reluctant to put an alarm on the vehicle, since he didn't have anything contents-wise to protect.
Second, he had done other passive interlock methods such as the headlights and horn, but passengers soon noticed those (as was pointed out on another post would happen) and most likely passed those on to the thieves...either that or they weren't done right, since they didn't appear to have been forcibly defeated.
tbirdman74, I'd be interested to see what some of your solutions may have been. Don't worry about your customers' security, since you don't have to furnish vehicle types (unless it's of note in the installation) and definitely wouldn't be asked to furnish location. PM me and I'll get my email addy to you if that would work best.
Thanks, all, for your suggestions, all have been noted and are being forwarded to the other installer for consideration and discussion with his client. At this point, he's got the defroster hooked up and working, but I figure he might need something else very soon if the same trend keeps up. Thanks again, everyone!

OK, this feller should realize that an alarm does a little more than protect contents I guess. If it is broken into, it will respond with bells and whistles, drawing attention to the vehicle, and thieves dont like attention. Second, most have a starter disable in conjunction with the alarm, so that if it is triggered, the vehicle will not start. And third, that little blinking light will about 90 percent of the time make a thief keep walking, just cuz of reason 1. But anyways, if you could email me with the year, make, and model, I will see what I can come up with. Also include any electrical options such as overdrive switch, power mirrors, traction control switches, things like that, they can be used as well.

[quote]can just short the starter under the hood, and presto, your ride just performed a Copperfield.[/quote] That is why I would use a passive fuel pump switch instead of using the starter. Past the relay in case of someone jumping the fuel pump prime type connections on some cars these days..

I read on an alarm tutroial, the guy used his window switch in tandem with turning the ignition switch to start his car, had to press the switch into the up position for the car to start...Would be better than the cig lighter since the window switch is on the left and ur right hand turns the key...Lemme see if i can find it.
k here it is:
Seems like a good idea. HERE
