    remote starters need hotwiring

    Ok now the subject line has got your attention.........

    Car immobilisers...

    I have seen a few types and there a problem!

    Why, because any 70/80's design car probably wont have one, so I can just go on ebay and buy a nice black shiny talking car alarm with LCD 5 mile pager and remote start with window closer and make it like fort knox

    Problem, if I have bought an 80's/90's car my ''freedom'' of choice has been taken away as the car will no doubt have an OEM immobaliser that wont work with an aftermarket alarm system.....

    Not an issue for me, I drive an early model that has none or on my 'executive model' a 4 digit pin, and you can turn it off into 'valet' mode so the pin does not need to be entered, hence I can use an alarm with remote start.....

    My question is, can you do that with your car?

    I know with some fords you can just tape a spare key with RF transponder behind the ignition switch so it has one to communicate with, allowing me to remote start it, but what about other systems?


    -----

    notes:

    1) I'm in the progress of writing software for a gsm/BT alarm / starter so I am trying to see how to make it work on a wide number of cars, not researching how to steal them, and information on how to circumvent alarms is out there, but usually only known by a few thousand inside, and i dont like the showers even for research....

    2) I know car starters are a grey legality in some countries maybe states, and thats not for discussion in this thread, if it bothers you so much and need to share you opinion, start a thread...

    3) I've been on the forum years so I've not just sprung up with this, although most of the discussion/early work was on the other carpc forums so anyone who knows me knows this is genuine research/pondering


    Oh BTW, early 80's fords, you could remove the side indicator and short the wires, and open the doors with tennis balls to drive away, so much for security!!!!

    when i installed alarms it was often suggested to let the alarm control the ground wire to the immobiliser module.... depending on the model it should enable you to start the car

    but i guess the modules are smarter than that
    Blessed are the "cracked" for it is they who let in the light.

    I know on my sons car he has chip in the key, thats read by a coil of wire wound around the ignition barrel where the key goes, it seems to be needed just to start but once running is ignored.

    I think mazda used the same on the bongo2/ford friendee

    seems to be a very common system, but i dont know if it has a wire that can inhibit it, would be very insecure if it did, but i do wonder if it can be switched off etc maybe via a diagnostics hookup to allow a remote starter

    it all seems to be done in the same tin box as the engine ignition/injectors ecu

    i think it is just a matter of having the right info, but i guess the system are more integrated now than before.... just a shame as it does not allow us to add extra features to the car we own

    The aftermarket usualls sees to that problem for most cars.
    Here's a quick search. There's several options for most cars. I only really have experience with the various GM anti-theft options. Some vehicles are as simple as finding the correct resistor value and soldering in a resistor to one of the wires going to the ECM. Painless Wiring makes a VATS (Vehicle Anti-Theft System) bypass module for installing newer (late-80's up) EFI engines into older cars. There's probably similar options available for Fords and most other cars.

    Good luck with the project. Sounds interesting. Keep us posted.

    Cheers,

    lol not seen that before, its missing a spoon

    yeah i like the spare coil/spare key/relay option to switch to a spare transponder under the hood or somewhere remote located, seem a good way to do this and to keep the the oem immobaliser working

    i guess that should work for most system except the keycard ones.

    Saw a nice fob on an 08 BMW few days ago, it just goes in a hole where the key normally goes, quite nifty.

    There are companies that sell immobilizer bypass units. These units are designed to connect to immobilizer systems and essentially "securely" and "temporarily" disable these systems.

    Do a quick search for "immobilizer bypass" and you should find three or four out there.
