Ignition Switch

[imported_kbininger]

I need to replace the ignition switch on my 96 A4 2.8. Is this switch programmed to the key or ECU? In my Infiniti, the key has a chip that must be programmed or the ECU is disabled, and that can only be done by the dealer. Needless to say, they will not work on a used part so I would need to buy it from them.

I can get a switch for my Audi on car-parts.com for less than $100. The dealer part is $400+. Will I be able to just install the used switch or will it need dealer programming?

Thanks for your help!
