I recently lost my only key to my 1997 a3 1.8 se.
It was the 2 button non flip type on 433 mhz.
Paid an auto locksmith £190 for a key cut and transponder coded to the immo.
The key they supplied is a standard HU66 AT5 non remote type.
So i purchased a 2 button flip remote replacement case minus the electrics from ebay.
I removed the transponder chip from the HU66 AT5 and placed it in the 2 button remote and had the blade cut.
The 2 button flip key starts the car fine.
However i am already sick of sticking the key in the door all the time i use the car.
I believe it is possible to programme a used 2 button remote to the vehicle using vag com.
However i do not know which remote to buy as there are many part numbers available.
I do have the part number of my central locking pump/receiver it is 8LO 862 257.
Can anyone help supply me with the correct part number of the remote that i need.
