I want to collect all kinds of car protection ideas in this topic.


1.
I have an alarm to which you can also record other remote controls.
It learns to recognize other remotes even if they have a rolling code.

This is my idea came from, to searching on the internet.

https://www.wired.com/2015/08/hackers-tiny-device-unlocks-cars-opens-garages/

The remote control code may be scanned with a very simple and inexpensive device.
The thieves pass near the car, touches it easily, and starts the alarm. Because it makes loud noise, you will press the button of remote to turn it off. At this point the thieves scanned the code.

Because the remote controls change their code every time you press, they do so many times.
So scans several successive codes and with the help of a computer they find the sequence of the remote control.

They sell such alarms because they also count on the goodness of the people.

I want to write the coding program myself to surprise the thieves. Take the micro controller out of the alarm and program it.
Would anyone be interested in this? Would anyone buy something like this?


2.
Some insurance companies require the car to have a GPS alarm.
Seems a miracle of technology this GPS or GPS/GSM.
But I can not believe it that thieves can not buy a GPS jam with nearly $ 100.
Then this system is worth almost nothing.

3.
I have more ideas but I'm gonna stop here.


Why ?
A bunch of new cars are broken by thieves. And the car manufacturer has no responsibility.
Have you ever seen a car manufacturer accused of how easy a thieves can attack his car ?

 

I will give you a few ideas.

First mechanical lock under the steering wheel or even better a locking pin inserted through the gear selector sideways, blocking the selector in a specific position. Mechanical device takes time to unlock, but I do not like mechanical devices.

Other option is to know the vulnerabilities of your car and to address them specifically. Owners of VAG and Renault cars in my country are removing the obd2 connector, scrambling the pins on the connector and moving the connector to some secret location. Now, if you have a Fiat which has obd2 connector as a part of its electronics box, you cannot do that. Some cars have wiring, LIN and CAN, near the surface of the outside, so the wires can me moved away, so someone cannot drill the side of the car and connect to the CAN. Some people are fortifying the inside of a door to avoid drilling through the lock assembly.

There is also a question if it's a something that you would do when parking the car for extended period of time (like vacation) or something that you would do every time you exit the vehicle. I would be pissed if I would need to use one or two mechanical systems every time I exit the vehicle. But there are electronics, so there are in every system positions that need power for the car to start. So my option is one or a few secret switches to control a relay which would disconnect power to a vital system (fuel pump on a petrol engine, power from ECM to the coil pack, starter control circuit), but it all depends on which systems are electronically controlled, and where you do at least harm to on-board electronics. If you get an error each time your protection kicks in, the position is not good.

Another option is to cut-off fuel mechanically or electronically. There are also mechanical systems that activate brakes when power to a vital system is disconnected, but I never liked these solutions. I have also seen a home made solution that turned the electric steering help to the furthest left position, but I do not like these system either. Anything that messes with steering or brakes is no-go for me. There are plenty of options, but every commercially available option is not secure enough in my opinion, with an exception of commercially available mechanical protections.

Best solution would be a factory alarm system, good mechanical protection for over night use, and a secret auto-engaging electronic protection. There is also a question what are you allowed to do with your car systems in function of the laws in your country and a manufacturer's guarantee.

 

I have two thoughts on car theft.

1. If a thief wants to steal A car, you make it very difficult for him. He will simply find a car that is easier.

2. If a thief wants to steal YOUR car, there is nothing that you can do to prevent it.

 

Here in Australia the thieves break in to the house to steal the keyes to the vehicle they want, usualy at night as all newer vehicles use keyes with transponders in them. If they realy want the car to strip it they just tow it away.

 

I have two thoughts on car theft.

Very true. Just recently I have heard about a situation where someone bought a newer car, wanted to protect it, used all the elements to secure the car (mechanical, alarm, communication port protection with high voltage to fry the thief's equipment, the thief has broken in, could not dive the car away. A week latter came, presumably the same thief, broken a window and poured some larger quantity of HCl in the interior and left the car. The whole upholstery was unusable in the morning.

My personal solution is to own a car that is not too young or too old, of a brand that is uninteresting or a car that is very liked and available in high quantities, so there is always a few streets away some other less protected. Owners of one of a kind and similar provocative cars may want to think about buying a dog and letting the dog sleep in the car (if not prohibited by local laws).
