Hello,

I have a friend that his this really cool security gadget in his car and I would like to get it in my car. The problem is, I don't know the name for it. Basically, in order to start the car, you need to put this key chain thing underneath the dashboard on the side of the cassette player, and it makes a "beep-beep" sound. Then you can start the car. Can someone please provide me for the name of this?

If someone were to try and steal your car, they wouldn't be able to hot wire it correct?

Also, any other security gadget advice would be greatly appreciated.

Thanks a lot.

Those things are so annoying. My in-laws bought 2 cars with those devices and I removed them. That should tell you what it takes to defeat such a device.

What happened to the ones that attached to you + side of battery and were activated by a remote. When activated they would allow just enough current to flow to keep clock, radio and such working. I believe there was even a battery manufacture that had these OEM on the battery. Seemed like a cool idea....

One of my cars was stolen, no security system would have helped it. It was quickly loaded onto a rollback and gone. I like the gps tracking.

What your friend has is an immobilizer with a proximity switch, this has a chip in the key ring and there is an Ariel hidden either in the steering column which means no dongle on key ring, no start, or hidden in the centre / radio area. Same principal as the touch pad system but invisible. it's a good system to stop the "gone in 60 seconds" thief, but a low loader beats all, (if your cars worth it and nothing under 10,000 is, Lojack or tracker is the best system backed up by a well installed alarm /immobiliser (cat2) forget makers systems, the first thing crooks do is hire the latest model, find out how to get around the security and then they can steal any similar model. Remember, thieves more often than not steal the keys first!

That's more than I dealt with. The systems I removed were nothing more than a card with multiple contacts. The receiver took a live wire from the ignition circuit and 'hid' it among the wire that should connect to the live wire and a bunch of grounded wires. If you try a wrong pairing you blow a fuse. It was a simple matter to break open the receiver and pair the right wires.

Do an internet search for 'starter disable' Most are integrated into more complex vehicle security systems but you might find the specific device you're looking for.

Thanks for the response.

So you had this type of gadget and it didnt work? They were able to start your car? I don't have to worry about it being put on a huge trailer since I have an indoor garage and those things don't fit in.

Thanks for all of that, now i have a name for it. WHat is this "low loader".? I just want to put this in a Mercedes Benz '85 300SD. If this isnt worth it, whats the best security to put on the car then?

So I take it that the gadget I am talking about isnt what you were talking about?

The card type immobilizer was just a holder with paired wires and a LED, the card when inserted made a contact with the correct pair and off you went, wrong card you either blew the fuse or nothing at all. The proximity immobilizers still have a box with pairs of wires and anyone finding this box (usually by following the antenna or LED lead), merely has to break it open and trace the pairs from the relay contacts and scotch-lok them together and off you go again. A GOOD system such as a Cobra or Clifford uses an encapsulated box so even if you get it open all the components are within a resin block and almost impossible to work on. Someone like myself with a basic 12v probe can normally get around such devices in a few minuets at most, even the best. 90% of the effectiveness of an alarm or immobilizer is in the installation. Just dropping the under tray off the dash and cable tying the box to the frame and running the wires to the nearest points required is a waste of time. properly concealed (buried) and wiring routed into the original loom and that recovered with the SAME type of tape, soldered taped inline joints not crimp-on connectors or scotch-loks and remote (radio) operated not touch pad and leave out the LED if supplied, it's traceable as above remarks.
If you want a "bugger off, I'm alarmed" LED get a 12v flashing one from your local component store, live to permanent live (+30) and negative to ignition controlled (-15), back of radio is a good place for both, when ignition is on you have 12v at both leads = no LED, ignition off and the negative side goes to ground and one flashing LED.
"Lo loader" is a car transporter.
"Lo-Jack" (USA) or "tracker" (UK) is a covert GPS system used in conjuntion with the police who have direction and strength detecters in their cars and can follow a stolen car at a safe distance and apprehending the */#2## who stole it. Not even the owners knows where it is and they shouldn't even tell ANYONE they have it, there are no stickers or warnings. Several makes / companies, all good. activation is by national digital radio system once the owner has reported the theft and the company phones back to confirm.
Wana stopo your car being driven off in the night or while you are away? Just pull off the HT lead from coil to the dizzy and put it in your pocket.

Wow you are very knowledgable, thanks. So what would you recommend for a Mercedes Benz 300SD '85? I want some sort of security on it, but apparently all of them seem easy to by pass. Anything besides the Lo Jack that is also cheap that I could install?

Further to my PMs the out come is;
Device = two cut immobiliser, encapsulted relays, remote opperation, seperate LED so not able to trace wires back to unit, (if an LED is wanted then buy 12V one from Radio Shack etc mount it in the dash (blank switch panel etc) and connect + to perm live and - to ignition wires on the back of the radio, it does work and no, it doesn't interfer with the radio.)
Pick a known brand name, (Clifford, etc) and have it installed by an certified installer who can issue a certificate which should then drop your insurence premium. If they say they don't issue a type approved certificat then go elswhere, do not accept any BS, like, "they are all the same under the badge", they are not!
Best advise is if you are not familier with car elecrtics or have not installed an approved type device before then DON'T do it.
