Hi All

When i bought my A3 it only came with one key. I am wanting to buy another key and get it coded but wondered if it was possible to use the newer key or not.

Cheers Steady

I have a feeling there may be an issue, I could be wrong but if they are anything like VW when I had my Golf I had the same thing just one key and I wanted to use the newer style fob and could'nt.

They have codes on them which relate to what frequency they are set to communicate with your car. So I would check your engine code against the fob code this will tell you the frequency and then you will know what fobs to use.I hope that makes sense, I am sure if I am wrong someone will come along and say. Hope that will help for now though.

I am going to put an order in and see what happenes but apparently you can.

But, you can buy these ebay keys and switch the immo chip over but you have to be careful as they are glued and could be damaged.

Surely, the window of choice would be a driver or passneger door window? Much easier to DIY replace with a replacement from a scrappy! [:D]

You can buy a fob and blade off ebay BUT the serial number has to much your current key. Then you can get the blade cut and take it to audi who can recode it.They only charge £25 or so to do it.

What serial numbers are people after i have a spare one floting around somewhere of a 2003 model

You still need it coded to the imobiliser fellas.

I to thought about one off the bay but when I spoke to a few dealers, they were reluctant to code one not suplied by them.

Also paying the 160 is that should anything go wrong for two years, you can go down there and demand it be sorted !

You dont get that off the bay.

But yeh, still pricey !

Thanks for that. I will have to check with my friendly service department if they would code a blank key and how much to code and cut etc.

Steve,

As above, you can code the remote locking part of a new key but you cannot code the transponder to the imobiliser yourself / with vagcom. Audi only for that part.
