The information we need can be found here:

The Security Code number on these radios are determined via a series of soldered links (or pad code) on the underside of the main circuit board. The bottom cover of the radio needs to be removed to gain access to the circuit board, and you will see from the pictures that there are only a few screws that need to be undone, but before you start to panic, if you have managed to remove the radio from the vehicle, then the hard work has already been done!!

Start by removing the 4 Phillips screws on the base:


And the 2 Phillips screws on the rear:


The two side mounting brackets will also need to be removed. If you turn the unit over and remove the 2 screws on the top, (one each side) this will then release the metalwork:


Now carefully prize off the bottom cover, taking care not to distort its shape and this will reveal the main circuit board as shown below. For orientation, the fascia should be pointing towards you, and you are now looking to identify a set of five solder pads as shown on the picture. These are all in a straight line, and once you have identified them, the next bit is very straightforward.

The five pads are made up of an upper and a lower section, and will look roughly like this shown below. Some will have a blob of solder linking the upper and lower pads, and its these blobs and their locations that we need to identify as a pad code.

If you assume an open, unsoldered pad to be a 'Zero 0' and a blob, or soldered pad to be a 'One 1', then with the fascia towards you, and reading the pads from left to right, you will end up with a five digit pad code made up of 0`s and 1`s. For instance this series of links below would give a pad code of 01001

By now you should be able to work out your own five digit pad code from your own series of links. If you now enter this information below by clicking on the boxes where you have a soldered link, and submit it to us with a payment, we can then instantly calculate your security code and display it here without any further delay.

Please be aware that if you have previously entered an incorrect number, or if your radio is switched on and you see four numbers on the screen, and no matter what you press they still keep showing, then the stereo may be Codelocked. If this is the case, then there is a little trick of the trade to get around this, but please be careful as it is also very easy to irretrievably lock the radio if the wrong buttons are then pressed afterwards.

With the unit switched on, press and hold the 'ST' button for around 10 seconds, and the display should disappear completely leaving you with a blank screen. If it does, then follow the email instructions that we send with your code number. If not, then please try leaving it switched on for 3 hours, and then try pressing the 'ST' button again. Should it not reset after this time then you may have used up all of your Code Entry attempts, and the radio will now have to be sent to us for extensive reprogramming.
