What should I do if my key is stolen?If a key is stolen, it is crucial to have the car "re-keyed" electronically.

Does a locksmith's key look various from the dealer's key?If the locksmith professional uses an OEM (Original Equipment Manufacturer) key, it will be identical. If they use a "universal" or aftermarket key, the internal electronics are typically the same, but the plastic housing may do not have the Audi four-rings logo.
My Audi A4 key won't kip down the ignition-- is the key broken?This is common in older B5 and B6 models. It could be a worn-out key blade or a stopping working ignition lock cylinder. Before ordering a brand-new key, a locksmith professional needs to examine the cylinder to see if it requires repair work.
