Default access control module

Do anyone know about how much this cost to be repaired I saw a red key symbol flashing and they are assuming that's the problem do anyone know anything about this I'm very frustrated it's a 2004 Audi a8

Default Sounds like a key not coded to the car

if you see a key symbol when inserting it into ignition, but nothing happens.
Current #1: '06 D3 A8L W12 brilliant black w/ amaretto; 4 seat setup, CPO; modestly lowered, H&R 20mm rear and 12mm front DRs with 275/35 on OEM polished + forged 20's; S8 sway bars (see: rear bar and gen'l D3 bar info and front bar); tweaked 385mm front factory brake mod and matching rear brake mod; matching C6 A6 back headrests (better rear view: headrest tweak); owner installed AMI retrofit with part number details here. [pics now only in picture poster] Upper control arm reference (+ more info in replies) here. Lower cost D3 OES sway bar links here.
Current #2: 2013 Q5 2.0T hybrid; Scuba blue w/ chestnut sport interior; Euro delivery 7/2013 (pictured at Ingolstadt); RS5 front brakes
Prior (each modded): 2000 C5 A6 4.2 & '96 C4 A6 2.8Q, both still w/ family; '85 C3 5000S 5 sp FWD; '73 C1 100LS

helpful cross reference to C6 MMI and various other TSB's that also cover D3 A8's.
