Don't pay or wait more than you need to for a Mercedes-Benz radio code. We generate all Mercedes-Benz codes instantly, so whether you drive a C-Class or an Actros, whether you listen to Heart FM or your own tunes – we'll get you back into your radio or navigation in minutes.
When your Mercedes-Benz radio, stereo or navigation becomes disconnected from the battery, usually due to a garage service or a low battery, it automatically locks and begins to ask for a radio unlock code. As this is an anti-theft feature it's not possible to unlock a Mercedes radio without this code, but finding your radio code is an easy process that can be done in minutes. Many dealerships and online generators decode the radio code from the VIN number, but this code will be incorrect if the radio has ever been changed in the vehicle's lifetime.
The most accurate way to get your Mercedes-Benz's 4, 5, 6, 24 or 25-digit radio unlock code is by decoding it from the radio's serial number. Our instant Mercedes radio decoder currently supports the following serial numbers:
There are two ways to find your radio's serial number – a fast one and a slightly slower one.
Because we incur costs and fees for every code we generate, our money-back guarantee does not usually cover codes decoded from incorrect serial numbers. For this reason you should always double-check that the serial number you enter has the same letters and numbers as the serial number on your radio. However we will always make exceptions in obviously confusing situations, such as when a Q looks like an O or an I looks like an L.
If your Mercedes-Benz radio or stereo has number preset buttons, you may be able to reveal the serial number on the display without removing it. While the radio is asking for a code, hold buttons 1 and 6 for at least 5 seconds and then release them. If nothing changes on the display, try the same with buttons 2 and 6.
If this method worked the display will show your radio's serial number, also known as the precode. This will always be 1 letter followed by 3 numbers – in the example image below it is Q981.
Once you have your serial number, simply enter it into our Mercedes-Benz decoder at the top of this page to generate your radio unlock code.
If this method doesn't show a serial number that looks like A123, or your radio/navigation doesn't have any number buttons, you'll need to use method 2.
Don't worry – removing your radio is not as hard as it sounds, and for most Mercedes models you won't even need to disconnect any wires. Simply slide out the radio from the dash and take a picture of the label at the top or side of the radio. The exact process depends on whether your radio has removal slots or not. Look carefully around the front of your radio for 2 or 4 holes: these will either be flat and key-shaped or square/slightly rounded.
If your radio has flat key-shaped slots (image 1), you'll need these radio release keys. If you're in a rush you can also try using everyday items that will fit into the slots, such as a few letter openers or thin bread knives - you'll need one for each slot your radio has.
If your radio has round or square slots (image 2), you'll need these radio release keys, or you can try using a few thin screwdrivers or barbeque skewers.
Once you have your radio release keys, insert each one into your radio's removal slots until you feel some resistance or hear a click. If you're using flat radio release keys, insert each key with the curved side facing the inside of the radio (image 3).
Finally, start pulling your radio out while pushing the release keys outwards, away from the radio - this will give them enough grip to pull out the radio. In most cases you won't need to disconnect any wires - simply take pictures of all the labels on the radio and click it back into the dash.
If you'd prefer to see this process visually, see this video.
If your Mercedes radio doesn't have any visible removal slots, the exact removal process depends on your radio's model. To find the easiest and most specific instructions for removing your model, search YouTube for your vehicle's model: for example, Mercedes-Benz W168 radio removal. For most Mercedes radios and navigations, the only tools you will need are a trim/pry tool and a T20 screwdriver.
Your Mercedes-Benz radio's serial number will usually look like one of the examples in this section above.
Becker models will have the 8-digit numeric serial number clearly labeled on its own. If this has worn out on your radio's label, you can also enter the full 15-digit barcode serial into our decoder (image 1). Alpine serial numbers are usually engraved on the radio (image 2).
Once you have your serial number, all that’s left is to enter it into our Mercedes-Benz radio decoder and generator at the top of this page.
Mercedes-Benz vehicles and radios that we are able to decode include:
Unfortunately, it's not possible to unlock a Mercedes-Benz radio asking for a code without entering the code. This is intentional as radio unlock codes were originally designed as an anti-theft feature to make it harder for thieves to steal and resell car radios.
Due to the costs of running a small business providing radio codes around the world 24/7, it's not possible to sustainably offer Mercedes-Benz radio codes for free. There are many decoding services out there that attract customers with the word "free" only to reveal a price at the very last second or fail to deliver a code at all (as shown by their reviews). Our prices will always be shown up-front, and our radio codes are already priced as low as possible while still allowing us to stay in business, provide reliable English-speaking support to customers and continue adding support for more models and manufacturers.
Not only were we the first radio decoding company to offer radio codes for all manufacturers at one fixed price, we were also one of the first to charge as low as £4.99 - before we came along virtually no popular decoding company offered radio codes at such an affordable price. To this day we still beat 95% of our competitors on price, without making you wait around for your code.
Unfortunately it's not possible to generate a Mercedes-Benz radio code from the registration plate at all. Although most dealerships and some online decoding sites do use the VIN to decode the radio code, this is not reliable due to being tied to the car rather than the radio. This means that if your radio was changed since it was first manufactured, a radio code decoded from the VIN will be incorrect. For this reason RapidRadioCodes - like most online decoding sites - decodes the radio code from the radio's serial number, which gives us the best chance of unlocking your radio.
All our Mercedes-Benz radio codes are decoded instantly, displayed on the screen immediately after payment and sent to your email at the same time. To ensure that your code and receipt are sent to you, double-check that the email you enter when paying for your radio code is correct. If it's been more than 2 minutes since you purchased your code and you haven't received your email, get in touch with us so we can look into why this might be. In most cases this is down to a misspelt email address.
This means an incorrect radio code has been entered. To bypass this lock leave the ignition and radio on for up to 2 hours until you're able to enter another code. If you're not able to enter a code after 2 hours, this means an incorrect radio code has been entered 10 different times - we call this a "hard lock". The only way to bypass a hard lock is to physically take the radio to a specialist with the hardware tools needed to clear the lock in the radio's EEPROM chip. However, this is a much more expensive process and it can often work out cheaper to buy a new radio. For this reason you should get in touch with us as soon as possible instead of wasting your code entries.
So you've located your serial number, entered it into our radio code generator, and received your decoded radio code in return. Congratulations! Now comes the best part: using your new radio code to unlock your Mercedes-Benz radio.
This process varies depending on your vehicle's radio. Each of our Mercedes-Benz radio codes come with simple instructions to enter your new code at no extra cost. To receive your entry instructions, double-check that your email address is spelt correctly at the payment stage. If it's been more than 2 minutes since you purchased your unlock code and you haven't received your email or receipt, get in touch with us so we can look into why this might be. This is usually down to a misspelt email address.
