Audi Tt Key Fob Not Working After Battery Change. If your key does not work after you change the car battery start the engine by pressing the START button with the keyfob. Next press the unlock button on the remote.
Not having a backup key made me a bit apprehensive because if I say accidentally locked the key inside the trunk orworselost it altogether a locksmith could charge 500 and replacing the entire ignition lock for a new set of keys could cost upwards of 1000. The key will work and no programming is required after you change the battery. Steps to program a key fob on an Audi.
Next press the unlock button on the remote.
Unfortunately I lost my second key and did not receive a valet. Use a spare key to turn the ignition on position. Dont touch the key fob circuit. Tonight were in the shop doing some light fabrication work as we install some of the aero gear for our project Corvette Z06.
