My friend recently bought an Audi A8 L. Problem is... he had to replace the battery. He got an autozone one with 950 CCA. However it started a couple of times with difficulty and now will not even power-up the DVD/Nav console. No clicking, no turning over on engine. Also the FOB battery was replaced, and the door locks no longer work with the FOB. Do i need to reprogram the FOB, and car battery, before checking the starter solenoid?

Please help
