Hi all,

I've always been a little curious about the software auto service providers use to get the correct parts for their customers cars, and now that I am buying parts online I am more curious about it as it would be quite handy.

A few examples just recently-

An automotive Air Con servicer could find out what cabin filter I needed for my car just from the number plate. 

Repco can also get all sorts of information on parts on their computers with just a rego plate number.

Even james bull and other lock smiths can order the correct frequency transponder keys (FOBS) with a rego plate.

Is it likely this is available online, or perhaps it is a subscription based software? 

Curious if anyone knows a bit more about this stuff.

Thanks,
