How do I find my Opel serial number?

When your Opel radio, stereo or sat nav 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 code (sometimes also known as the authentication key). As this is an anti-theft feature it's not possible to unlock a Opel radio without this code, but getting hold of 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 Opel radio code is by decoding it from the radio's serial number. This will look like one of the following examples:

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 refund policy usually does not cover codes decoded from incorrect serial numbers. For this reason you should always double-check that the serial number you enter matches the serial number on your radio's display or sticker label.

Method 1: the quick way

On some Opel radio or sat nav models it's possible to reveal the serial number on the display without removing your radio. While the radio is asking for a code, hold down buttons 1 and 6 on your radio for up to 10 seconds - if it works this will show the last 4 characters of your serial number on your display. This will always be 1 letter followed by 3 numbers, e.g. A123. If this doesn't work, try holding 2 and 6 instead. If your serial number still doesn't appear on your radio's display, you'll have to remove your radio to reveal the serial number on its label.

Method 2: removing your Opel radio or sat nav

Don't worry – removing your radio is not as hard as it sounds, but it is the hardest part of getting a radio unlock code, which means that once you've done it the rest is easy. The exact process depends on whether your radio or sat nav unit has any visible removal slots or not. Look carefully around the front of your radio for 4 round pin-shaped slots.

If your radio removal slots are spaced apart like in image 1, you will need these single-din radio removal keys.

If the slots are spaced wider apart, you will need these double-din removal keys. In a pinch you can also try using everyday items that will fit into the radio removal slots, like thin screwdrivers or barbeque skewers, bearing in mind you'll need one for each slot.

Once you have your radio removal tools, insert them into the slots, pushing until you feel some resistance or hear a click. Finally, start pulling your radio unit out while pushing out on the removal tools - 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 insert it back into the dash.

If your Opel navigation system looks like the one pictured below, the hardest part will be removing the outer plastic trim or fascia. This is held in place by clips at the back of the radio, as shown by the locations of the arrows (image 1). You should be able to undo these clips by firmly pulling away from the radio with your fingers or a flathead screwdriver - in a pinch you may also be able to use a bread knife. Once you've undone the clips, slowly but firmly pry the plastic trim away from the radio, revealing the 4 screws keeping the radio in place. After unscrewing these using a cheap Torx 20 screwdriver, you will then be able to slide out your radio.

In most cases you won't need to disconnect any wires - simply take pictures of all the labels on the radio and insert it back into the dash.

If you'd prefer to see this process visually, see this video.

If your Opel sat nav unit looks completely different to the one in the image, the exact process and tools needed to remove the radio can vary widely. You can find the easiest, most specific instructions by searching YouTube for your vehicle's model and model year - for example, how to remove Opel Astra 2014 sat nav.

Identifying your serial number

Your Opel radio's serial number will look like one of the examples in this section above, starting with either GM, BP or random numbers.

If your serial number starts with 28 or 82 you don't need to enter the full serial number - just the last 4 characters. This will always be 1 letter followed by 3 numbers (image 3).

If your serial number starts with GM or BP (image 4), we may also require a part number to guarantee that the radio code we generate for you is accurate. This part number will start with 7 6 and be located on the same sticker label as the serial number.

If you're still having trouble identifying your serial number, simply contact us with a picture of your radio's sticker label and we'll help you identify it at no extra cost. Once you have your serial number, all that’s left is to decode it using our Opel radio decoder and generator at the top of this page.

Unfortunately, it's not possible to unlock a Opel 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 Opel 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 Opel 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 Opel 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 the code is ready to be entered, where 10 is the number of code entry attempts remaining. When an incorrect code is entered this number will decrease and you will need to leave the radio and ignition on for a while before you can try another code - how long depends on how many incorrect codes have been entered so far, starting from a few minutes up to 11 hours. If an incorrect code is entered 10 different times the radio will become "hard locked" (see below).

Hold the power button and the AS button until the display shows 10 SAFE, 9 SAFE, etc. If the display stays stuck on SAFE, this likely means an incorrect radio code has been entered 10 different times - we call this a "hard lock". Try leaving the ignition and radio on for at least an hour then press AS and the power button again. If the lock still hasn't cleared, the only way to bypass it is to physically take the radio to a specialist with the hardware tools needed to reset the lock in the radio's EEPROM chip. However, this is a much more expensive process and it can sometimes 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 Opel radio.

This process varies depending on your vehicle's radio. Each of our Opel 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.
