weslangdon Posted March 23, 2015 Report Share Posted March 23, 2015 Hi, my Arosa Sport's remote key has gone missing leaving me with just the one key, so today I had a "coded" key cut with a chip coded to my car...or so I thought. The key will illuminate the ignition, showing all the potential fault codes and warnings, will operate the starter motor but it will not fire up. Returning the key to the shop, the supplier double checked the coding and concluded that the code had changed and that the chip in my original key is continually changing. Does this make sense to anyone here Quote Link to comment Share on other sites More sharing options...
BlackArosa Posted March 23, 2015 Report Share Posted March 23, 2015 Sounds like they're trying to fob you off. (Pun intended) 1 Quote Link to comment Share on other sites More sharing options...
Keelan Posted March 23, 2015 Report Share Posted March 23, 2015 That would be useless. It's one code that matches the car. That's it.. 1 Quote Link to comment Share on other sites More sharing options...
Dblock Posted March 24, 2015 Report Share Posted March 24, 2015 Skezza is your man but don't the codes change to stop people nabbing your code opening your car. Maybe that's on cat 1 of high end systems only. Quote Link to comment Share on other sites More sharing options...

Skezza Posted March 24, 2015 Report Share Posted March 24, 2015 The remote uses a hopping code which is constantly changing. The ignition uses an ID42 crypto for older Lupos and ID44 for newer. These are fixed hash, so don't changer at all. You need to adapt the transponder using VAG COM and your SKU. VW won't give them out anymore so you'll need to buy a cheap VAG TACHO clone and see if you can get it that way. Pre 2002 guaranteed work. >2002 some have IMMO3, these are harder. 1 Quote Link to comment Share on other sites More sharing options...

Skezza Posted March 24, 2015 Report Share Posted March 24, 2015 You would very possibly be able to do it yourself then!! The only Lupo's with IMMO3 are 2002 onwards and to be fair, many were still fitted with IMMO2. A friend who is a VW engineer said VW only guaranteed IMMO3 on GTI's and plenty of post 2002 non-GTI's were fitted with IMMO2.So, if you want to save yourself £105, buy a VCDS, buy a VAG-TACHO, get your SKU, adapt your two keys using VAG-COM and the standard adaptation process (google it) and then enjoy your new keys and your new equipment which you'll no doubt use down the line. 1 Quote Link to comment Share on other sites More sharing options...
