Audi radio code: everything you need to know
The Audi car radio security code is a 4-digit code that unlocks your radio after a power failure. Once the battery in your Audi has been replaced or disconnected, "SAFE" appears on the display and the radio is blocked until you enter the correct code.
At RadioCodeLookup.com you request the Audi radio code via the serial number of your radio. You can find this serial number by pressing buttons 1 and 6 simultaneously while the radio is on, or on a sticker on the radio after removal. Audi serial numbers often start with "AU" followed by digits.
Our service covers all common Audi models, from the A3 and A4 to the A6, TT and Q5. We deliver the Audi car radio code quickly and reliably, directly to your inbox.

Where do you find your Audi code?
Retrieve the serial number via P.SCAN+RDS
Hold the "P.SCAN" and "RDS" buttons (or "SCAN" and "RDS") simultaneously for a few seconds while the radio is on. On Chorus II, Concert II and Symphony models the AUZ serial number will appear on the display. Note it down in full.
Remove the radio (if display does not work)
Cannot retrieve it via the buttons? Insert four round DIN extraction tools into the holes on both sides of the radio and slide it 5–7 cm forward. The AUZ serial number is on the white label on the side or top: starts with "AUZ" and is 14 characters long (e.g. AUZ1Z41234567).

Everything you need to know about retrieving and entering your Audi car radio unlock code.
How do I find the serial number of my Audi car radio?
On most Audi models, hold buttons 1 and 6 simultaneously while the radio is switched on. The serial number will appear on the display. If this does not work, the serial number is on a sticker on the top or side of the radio, visible after removal.
What does "SAFE" on the display of my Audi radio mean?
The message "SAFE" on your Audi radio indicates that the anti-theft lock has been activated after a power interruption. This is a standard feature in all Audi models up to approximately 2014. You must enter the 4-digit radio code to unlock the radio.
Which Audi radio types are supported by RadioCodeLookup.com?
RadioCodeLookup.com supports the most common Audi radio systems, including Concert, Symphony, Chorus and Bose systems. Both the simpler RCD models and the more advanced MMI systems before 2015 are supported.
How do I enter the radio code on my Audi A3 or A4?
Use preset buttons 1 through 4 to enter the four digits of the radio code. Each button increases the corresponding digit by one. Confirm the complete code by holding the seek button or pressing the OK button. Check your manual for the exact entry method.
Why does my Audi A6 or Q5 ask for a radio code after a battery change?
Audi has the theft protection built into all car radios up to approximately 2014 as standard. After any power interruption — including a simple battery change — this protection is activated. This makes the radio unusable when it is taken outside the vehicle.
How quickly will I receive the Audi radio code via RadioCodeLookup.com?
After payment, you will receive the Audi car radio code directly by email, usually within 30 seconds. The service works 24 hours a day, 7 days a week. So you do not have to wait for opening hours or a response from a dealer.
Can I also retrieve the Audi radio code from the Audi dealer?
Yes, an official Audi dealer can retrieve the code. Please note that this usually involves costs and may take one to two working days. Via RadioCodeLookup.com you receive the same code immediately and more cheaply.
What do I do if my Audi radio has received too many incorrect codes?
If your Audi radio is blocked, leave the radio switched on for at least 1 hour. Then try again with the correct code from RadioCodeLookup.com. Never enter random codes if you do not know the correct code, to prevent further blocking.
