Question edited for clarity.
Question moved to model category.

It is a Mercedes, you need the dealership, an auto electrician or an Auto locksmith / Alarm installer. It is the most electrically over-engineered brand on the market. some are PIN Locked so that only registered technicians can reset based on VIN Number.

You should have a code for the radio in your owner;s manual. If you are not the original owner and it is not there, the dealer should be able to provide it from your VIN.

Hello, Yes, many MB cars have security codes built into the stereo header units, including my own, (a theft deterant) You never really need to input it til you lose all battery power. If you have the orig. owners manuel it may still be in there. If not you may be able to get the code from the MB dealership using the vin number. Hope this helps a bit.

The code should be on a card that came with the owners manual. Usually everything is located in the leather case assuming the procedures are the same there as well as other locations. Otherwise, you will have to call the dealer and provide them with VIN and what other information they request for proof of ownership.

This is just a web site people use

No one would have any codes for anything on a vehicle

Codes are for security reasons

Need to go to a dealer & prove you own it
they will help you

cannot calculate from vehicle vin need the radio chassis number but if this is a 2005 then its a dealer only job with diagnostic equipment ,when you do get code write it on the sun visor for safety

Wait 24 hrs and have the code from the owners manual and type it in.

hello

Call your Mercedes dealership or any Mercedes dealership give them your VIN and they would be able to give you the Code usually they will give you the code for free

Call the dealer and give them your VIN number. If that does not work you might have to take the stereo out and give the dealer Serial # for that radio. Good luck!
