For an Audi A4 owner, the process of getting a brand-new key involves a number of logistical steps. Due to the fact that these keys are linked to the car's Vehicle Identification Number (VIN), security is a leading priority.

In B8 models where the key is pushed into a slot, a stopping working battery or a transmission not in "Park" can cause the key to end up being caught. Ensure the car is completely in Park and the battery has a charge. There is frequently a manual release pinhole near the key slot.

This is generally not recommended. The majority of Audi keys are "locked" once they are configured to a VIN. A used key can not be reprogrammed to a different car unless the transponder chip is physically changed and the remote is "opened" using specialized hardware-- a service most locksmith professionals will not provide for customer-supplied parts.
