Re: Stopping your car
in WA to register a vehicle you must have either one of the following:
- Factory Fitted
- Government approved (ie, self arming without assistance from operator)
The problem with immobilizers is all they do is jam a relay to the return fuel pump wire, and the starter usually, some have ignition cct cutoff's (which are really dodgy because this means you can simply power the ignition by shorting the ECU relay under the bonnet)
I would have to say smartlock is one of the best immobiliser systems made, however, as advanced as it is, it is still Mrelay controlled, one you put the key in, and turn it, it sets off a signal to de-activate this amazingly advanced injection programming computer.
The only decent anti-start devices are ones where the operational circuitry is dependent on the remote circuitry in order to function, not in order to verify that its allowed to function.....I mean taking this out of proportion you could open your computer up, find the MPU, run external wires to a female plug mounted on the dash somewhere, and disguise your MPU into like a "keycard" or "remote control", and then insert it when u get in the car. obviously you wouldnt bother, but the injectors cant run without a processor, and u cant just "hotwire" where the processor goes. Ford could have done alot better as smartlock is quite easy to get around.
the anti-theft i have for my car: long wire going from input terminal on fuel pump (in the tank, not outside on the wiring clip), to a remote control receiver mounted behind the radio, to its original send wire. This also controls the IGN coil.
without pressing my remote, the coil produces no spark and fuel pump doesnt work, sure you can hotwire the coil easily, but if you tamper with the cct the fuel pump no longer has any input wire therefore no juice. Still relay controlled but alot better hidden, designed, and failsafe than most designs.
