Hello.
about universal, yes it can done to adapt all kind part number on a5 a4 q5 ....even what number is it or even the keys are from china, but the different in the remote control is the frequency 433mhz and 315mhz or 868mhz dose not accept to work lock unlock central locking system or if the car is keylees go,must be same frequency. 2 times my customer give it to me chines remote it done with me. but the others all i work on original remote control.

Chinese keys some models not start car, write " safe" on dash.
original keys can be 315, 868, 433 mhz and keyless not keysless, all work good

I've tested these keys and all work great but I didnt use them on A5,Q5 and dont know if they fit to new A6. I know that freequency has to be the same.

So when freequency match there should be to problem with remote (A4,A5,Q5,A6) as transponders are all the same PCF7945AC HitagExt ??

Hello.
first you must know what kind the remote frequency 315mhz or 433mhz or 868 mhz, when you be sure what kind freq, so after it accept to program starting system to bcm,after programming the key automatically it work lock unlock system. yes a4 a5 q5 those all are same transponder which can accept to adapt.

Can dealer adapt virginised used smartkey straight away or need to be precoded to car first?

edit: ok I found answer, it need to be precoded. Dealer cant adapt used virginised key very annoying for audi keyless owners especcially cars 2015+
