Just a quick question for everyone to answer. What is the point of Starter Kill when anyone who is going to hot wire your car will just bypass it anyway?

its to prevent the ign from being broken to start the car. If there is a starter kill and I use a screwdriver to break the ign the car will not start. starter kills are good but if you use a ign kill plus a starter kill and a fuel pump shut off relay all in one the only way someone is going to steal your car is a tow truck.

Assuming you have a hood lock together with a starter kill which prevents anyone getting to your battery and starter - it is going to be difficult for a thief. with a starter kill but no hood lock - i would like to hear from the other more expirence installers about this one....

if I was a thief...(I'm not) but if I was and I tried to steal a car, if I tried to hot wire it I'd see the starter wire and ign wire and hot wire it if there is a kill on the starter and I can find the starter side of the relay I can still hot wire it even if it has a hood lock because I don't need under the hood all the wiring is under the dash. An ign kill with a starter kill just makes it more difficult, now there's two things to find. If you also add a fuel shut off relay now there's a 3rd thing to find (even harder if you hide the relay somewere else in the car). even after hot wiring a car you still have to brake the ign lock to brake. If the thief gets under the hood the only thing he can do is cut the siren or disconnect the battery. With the battery disconnected the car can't be started so I'm not sure that the hood lock would help, except if would had motor work you did not want to disappear.

How would one wire a fuel pump shut off relay? I think that is the ticket since an ignition kill relay is the same situation as the starter kill. However, But couldn't an experienced thief just unplug the remote starter and the trigger that would be flipping all these switches (namely the ground out when armed) would flip them back and there we are again with a simple break of the ignition lock? I am simplifying all of this to save from typing it all, but I suppose the point is to deter a thief since it is nearly impossible to completely prevent theft. I am also assuming that we want a completly normally car with a remote starter. No one wants to have to hold a hidden switch to start their car,like I've seen suggested.

That's one reason why it's important to make the alarm hardware and wiring as inconspicuous as possible. If the alarm is mounted, say, in the console or under the seat and carpet, and the fuel pump cutoff relay is too, then the thief has to either rip the console out quickly, or cut off the power supply to the alarm brain in addition to the starter kill( and that won't do much good if you have a backup battery mounted with the brain, in the console).

I think it depends on how the relay is wired on the fuel pump relay. If you use the ground when armed for the relay, when the alarm is on the power for the fuel pump will be shut off. So if the theif ripped out the brain the relay would not work. But if there is power out when not armed and off when disarmed( I'm not sure if there is, it's been awile since I've installed ) if this wire was used on the same relay than the only way the fuel pump will work is if the relay gets power, so if the brain is ripped out the car will still not start. I'm not sure if there is a pwoer out when not armed but if there is not I think the alarm companies should introduce it. The battery back up is also a nother good idea I forgot all about them, looks like I'm going to get on for my car, Good Call thanks

Ok, so this thread has been very enlightening to me so far, so I want to shift it slighlty in a differnet direction. As far as I can tell, the factory anti-theft devices seem to me to be very good devices at least as far as I can tell. I would be interested in some statistics on how many of each type have been stolen. I am really only basing my thought that they seem like good devices is because I cannot think of how I would hotwire one. The transponder type devices do however make me a little sceptical. I mean the transponder is right there under the dash for a thief to use. All he has to do is smash the shroud and trace the wire coming from the coil to the transponder either in a key or one that has been removed from a key. either way it seems pretty easy for me unless you just dont have a remote starter, which then in my mind makes it nearly impossible to steal. I just want to hear what everyone thinks about these anti-theft devices and if there are ways thiefs can get around them.

You are correct about the fact that only RS units have the bypass modules and the spare key. The only way a thief is going to know this before hand is if they scoped out vehicle before hand and saw if being remote started or they live in Canada  . As far as a starter disable, I do not install one of these if it's a manual transmission vehicle ( senseless option seeing that you can push start the vehicle ). I like the immobilizers the manufacturer's have inplace now ( pain in the @$$ to bypass some of them ) but they have lowered to theft rate alot, but not the break in rates. People still have problems with theives breaking into the car, not to steal the car but the contents. If a thief has the time and the knowledge of the bypasses, he can get away with anything. As long as the hardware is not visible or accessible to the thief,he/she cannot bypass the immobilizer. ------------- Jeff
