These fobs allow for keyless entry and push-to-start ignition. The car finds the fob's presence via proximity sensing units, needing no physical contact between the key and the ignition.

4. Can I purchase an utilized Audi key from eBay and utilize it?
Generally, no. The majority of Audi fobs are "locked" to the original lorry's VIN once programmed. While some specialized locksmith professionals can "unlock" or "re-virginize" an utilized chip, it is typically more expensive and less trusted than purchasing a brand-new, unprogrammed chip.
