Our service is personal, not automated. Not sure which numbers to give? Send all you see on the casing and we'll check for you.

We aim to respond within a couple of hours, a little longer at weekends. If you're in the USA then please bear in mind the time difference to UK (we're 5 hours ahead of US Eastern time). These codes are our standard cost of £7.95.

After submitting the form, you will be forwarded to our Payments Page. Your request will not be actioned until payment is received. Our service is inexpensive but it is not free. We aim to give a good service with the assurance of our money-back guarantee: If we are not able to supply the factory-set code for your unit, we promise to refund you less 95p to cover payment processing.

Anti-tamper labels applied to the case of the radio will often overlap the back and top, or top and side panels. Look to see if such a label is torn along the line where the panels meet and let us know if you see this. It might indicate the radio has been previously repaired and the code physically reset. Let us know if you see a broken label.

You will need to pull the radio from the dashboard to read the serial number from its chassis - this will be on a printed label, engraved on the metal case, or both. Most of the units are extracted using 'keys' - if this is the case with yours, you will see small slots each side of the faciaplate. Don't be tempted to try removing the radio another way or force it as you may damage the surrounding dashboard trim. The keys make it very easy - you can find them in motoring stores or online.
