I understand that when buying a new key the transponder has to be coded to the immobiliser. This requires the use of vag-com and vag-tech I believe. Can anyone tell me whether the transponder from one car can be recoded to suit another immobiliser or is it a 'once only' operation? That is, can I re-use a second hand transponder? I have fitted an AGG engine into my Transporter so don't actually need the Golf key, only the transponder. I have only one key and need to create a second or spare. thanks Gary
If it's the correct type to match the transponder. If you can get another key for the golf from a locksmith. Code the key to ecu with vag tacho. Then get get a key cut to fit the transporter and swap transponders over. I only say this because I'm not sure if the transponders are the same type.
The Transporter key is a plain, flat metal key. No plastic cover or transponder. I will be using the Golf 3 immobiliser and receiver aerial ring (around the key barrel). Am I likely to be right in thinking that all MkIII Golf keys are going to have the same type of transponder? If I can get a second transponder coded correctly (preferably a 2nd hand one re-coded) I will bond the transponder to the Transporter key with resin or something. thanks Gary
You will need a matched immo box and key 1st , before you can code a second key. Why can't you use the key you have already and attech that to the ring ?
Depending on whether they're available (and if you want ot go this route...) These http://cgi.ebay.co.uk/MK2-flip-key-...16728576?pt=UK_CarsParts_Vehicles_CarParts_SM are available to fit http://cgi.ebay.co.uk/Volkswagen-Fl...939656?pt=UK_Car_Parts_Vehicles_Automobila_ET I got hte blade for my Rocco, but I think they are available for all manner of early cars. Hope that helps, plus means no faffing about with resin gluing!!
what is the code on your key blade? HV/AH/?? If its AH code then you can buy a MK3 AH key blank with chip from ebay or the dealers, get it cut to your locks and then swap the working chip into it. or as above chop your key up so it fits a MK4 type flip fob. However rather than getting a gen vag fob which wont work with your locks, get an rclick.co.uk central locking kit. They are available with MK4 type fobs, and since it comes as a kit you can fit the cl to your van. The rclick fobs have a space inside for the transponder chips, this is what I have done on my MK2 To code another chip you need vag-tacho to get the SKC for your immobiliser box, this will only work if you have a matched key in the ignition (or, a matched chip stuck to transponder ring with ignition on ) Then you can use the SKC to add more keys with either vag-tacho or vag-com.
Thanks John for confirming that with Vag-com and Vag-tacho the transponder can be re-coded to match an existing one. All the AH keys I have found advertised are without transponders. Looks like I will have to go to dealers and fork out 25 to get one! cheers Gary
The one in my existing key is a loose fit in a moulded compartment in the plastic key top. It may originally have been glued in place, perhaps. Garyd
