2002 Audi A6 Quattro Q&A
2002 Audi A6 Quattro Question: Keyless remote not working.
you key has two components: (1) remote transmitter that unlocks the doors and trunk. may use a replaceable battery; some like BMW recharge the permanent battery (2) a metal key that fits in the door tumbler and/or the ignition switch if the metal key no longer works, it could be the key is worn out or the tumbler in the door is defective. try your extra key and see if that works. also try both keys on the trunk lock. you may need a whole new key; available only from the dealer. - overbys
