Stopping thieves (car immoblizers)

Post by Hoonz »

so any way i thought seeing as so many 4bys are getting stolen
what are people doing to stop these arseholes taking our pride and joy

Are the car alarm kits you buy from autobarn or the likes worth the money?

please state what 4by you have and what mods u have done to stop these pricks ....





this could possibly go in general chit chat ... but theres
tech in it ... mods move if u think so

I have a Laserline car alarm in my Lux.
In my old car I had an alarm but also hooked up a cut off switch to the elec fuel pump. I had it hidden in plain view... wired into the demister switch :D and had the demister switch on a plain switch.
Another good idea is to get the good old engraver and put your drivers licence number on everything (stereo CB etc).
At least if it does get taken it might come back to you.

an immobiliser will stop ya general joyrider 17yr olds, not the pro's.

a hidden (though usually easily found) killswitch that comes from the loom going to + on the coil and basically turns off the power to let it run is your $3 option.(flamesuit on)

There's alarms out there and I'm to lazy to search to give you the links that will almost literally cause pain to the would be theif from the sound. there's also certain fuses that if the car is "jumped" will blow.
but again, if your not up and outside in around 3 mins you'll see your brake lights at the end of the street if its a professional theif.

or just do what a mate does and carry your rotor button around in ya pocket!

If a professional car thief wants your car, give him (her?) the keys. :?

Some years ago I heard of a "custom" RX4 which was parked at the top of a drive with two cars behind it, rotor removed. Next morning it was gone.

There's a standard for car alarms these days, one that insurance companys want before they give credit for it. Amongst other things, to meet the standard all wiring must be black.

Best alarm I ever heard of was a kit from one of the electronics magazines. If it wasn't switched off, the engine would start and run normally, but then die after 20-30 seconds (by earthing the coil.) Turn the key, would start and run for another 20-30 seconds. Theory was that the typical thief would lose their nerve and run, rather than take time to find the problem.

Cheers,

Scott

pretty much true, if they want it they will take it.

Black wired alarms are the standard, but what do you do if it fucks up in the bush? all wires are black. :?: Most insurance companies wont insure you now without one (READ THE FINE PRINT ON YOUR POLICY- DUDE IN OUR CLUB NEARLY FOUND OUT THE HARD WAY)...

alarms arnt really that hard to get around, when it gets installed talk to the installer and ask questions, i have found that they will tell you how to bypass it if stranded in the middle of no where,

i know my installer did,

i've heard of the RX thing as i used to own an RX of my own, real scarey when you have that much money tyed up in a '70's car.

the real truth is if a theif want's your car they'll take it. no imobalizer will stop a tilt tray :!:

but do what you thing is going to help, i'm relying on my factory imobalizer, something to do with turning off the computer, it'll fu@k up the casual thief, won't stop the pro though.

i say if a pro wants a rock rashed, beaten and scratched piss poor zook then go a head take it. but if i find you you'll want to die of naural causes, 'cause i'll make it real slow and painful (even if i have to give you a blood Transfusion to keep you alive)


GO AHEAD AND MAKE MY DAY

I wish I had an alarm that would explode if tampered with. Im willing to see my car burnt as long as the thief is dead.
Dont expect mere proof to sway my opinion.

On a previous car I had a kill switch that earthed the coil so it wouldn't start. Didn't stop them gutting out the interior while I was at tafe though. Is there a way you could wire a kill switch in a diesel?

You cant stop thives if they want it, my mate had his GTHO stolen from his garage and it was chained to the concrete, alarmed garage and two cars parked in front. He was on holiday at the time and it was well thought out. I have a tracking system in my nissan patrol. Its overkill, but i had it in my SS commodore and when i sold it i got it transfered to the nissan. It will be coming out and going in my new commodore soon and i will get a good black widow alarm with a multiple rolling code immobiliser(spelling?)

What about mounting a sparkplug in the fuel tank (petrols), and running a lead to it, that you plug in when you park.

That way if I cant have it neither can they...

Most times stolen 4b's are never seen of again from what Ive seen on forums in last 4 yrs.
=========================

Suppose the scums family would try and sue you

Like the thieving scum in Shitney who stole a KTM which had a flat tire he went splat. :armsup:

He rode off 3am flat out up the road, flat tire cause lackage of steering scum then hit a parked car up the road and was scum was found splatted across the road at dawn :armsup: :armsup: His story to the cops was "he was test riding the bike"

The family of said scum tried to sue the owner of the bike cause of the flat tire caused his injuries.

How the fuck this shit gets to court is beyond me.

About $30-50.00 from Jaycar or Dick Smith. Was quite big in the mid nighties (meaning it was advertised quite a bit in mags and catalogues)
Works well but. Could modify a simple timer to do the same thing if you happen to tinker with electronics at all.


>Is there a way you could wire a kill switch in a diesel?

Got two on mine - hidden switches under dash. One cuts the starter solenoid wire from ignition and the other cuts the wire to the fuel shutoff solenoid. Both work well. The above kit could just run/cut the fuel solenoid wire --- so in effect she'd run for 20 seconds and then die.

You can make a great hidden switch called a reed switch.
You hide this anywhere in the interior behind some plastic and all you have to do to trigger the stich is run a magnet past it.

More detail in this word document:
http://home.att.net/~email.id/ADESystem.doc

Think of somewhere creative for the switch. :)

G'day,

A Scary thing I discovered recently (bought a car that turned out to be a bit dubious) is that Different States have seperate databases so if your car is nicked you need to ring every state seperatly to report it stolen!!

I recently bought a car and did a Vic roads check on it, after I bought the car and started having problems they then informed me that the check only covered victoria and since the car was last registered in Qld I should do a check in Qld as well!! (thanks for telling me after the effect :x )

Scary really that you can steal a car in one state drive to the next and sell it with very little chance of the buyer even knowing its stolen even if they do a check!!!

Catcha.

Another idea for a diesel is a fuel shut off solenoid in line and hidden near the tank, wired to a secret switch somewhere.

nfi if this would work ? if i knew that much bout auto electrics i wouldnt be a forklift driver :finger:

Any idea where you could get a magnetic reed switch? (Dicksmith, Jaycar) Sounds like a good idea.

Here is a link to one, they are new to me -top idea!, if I can find one that will handle 12v and fit a fuel shut off solenoid it will make a great backup for my already installed kill switch. For those times I get the heeby- geebies leaving the car alone.

In my MQ i've wierd the cigerate lighter to the fuel pump , so unless the cigartee lighter is pushed in it won't start. That way it looks normal when your parked. Works a treat.

Black wired alarms are the standard, but what do you do if it ***** up in the bush? all wires are black. :?:
If you have even a slight knowledge of things electrical the black wires are quickly figured out. Soon as you rip some panels off, the wires stick out quite noticably because they are all black. The wires all being black only cause confusion at the plug end into the unit, where the ends are spliced into the cars harness is simple to work out, resort back to the cars original wiring colour to figure out which wires have been cut and need to go back together.

Thanks for that................where do you live :lol:

Did you have to modify your ciggy lighter to make it a switch? Can't see how it would work otherwise.

If the alarms installed properly (very few are....) the black wiring should all be integrated into the factory wiring looms and covered up. They should not be visible unless the loom covering is removed. The alarm module should also be hidden high in the dash out of view.

Personally I won't be posting on the Internet how my alarm is wired in and what it disables! :lol:
