Radio Code Card Location

When your stereo asks for a code after a power cut or battery change, the first place to look is the small plastic card — usually credit-card sized — that the manufacturer supplied when the car left the factory. This guide explains exactly where each brand typically hides it, and what your options are if the card has gone missing.

Where Manufacturers Typically Place the Radio Code Card

There is no universal hiding spot, but most original equipment manufacturers (OEMs) favour one of five locations. Check each in order before assuming the card is lost.

• Glovebox: The most common location — often tucked inside a card holder pocket or slid beneath the plastic lining. Check the very back of the glovebox and any secondary trays.
• Service book wallet: Many manufacturers staple or clip the radio code card to the inside cover of the service history booklet, which is typically kept in the glovebox alongside the owners manual.
• Key wallet: Some manufacturers (particularly Volkswagen Group brands) pack the code card alongside the spare key in its own small wallet at the time of sale.
• Owners manual: The card is sometimes tucked between the pages of the manual, especially in models from Ford and Renault.
• Dealer delivery envelope: For newer vehicles, the card may still be inside the original delivery pack provided at first registration.

What to Do If the Card Is Missing

If the original card cannot be found, do not despair. The code is not lost permanently — it is derived from the radio's unique serial number, which remains embedded in the unit itself.

1. Locate your radio's serial number by using the unit's built-in display sequence (press and hold specific buttons — method varies by model).
2. Alternatively, remove the radio using extraction keys and read the serial from the label on the side or top of the unit.
3. Submit the serial number to an online retrieval service like MyRenaultRadioCode.com to generate your code instantly.

In most cases, an online code retrieval is faster than visiting a dealer and costs a fraction of the price. Visit our brand selector to begin.

Frequently Asked Questions

Can the dealer always provide the code?

Most franchised dealers can look up a code using the vehicle identification number (VIN) and radio serial, but this typically requires a formal booking, proof of ownership and may incur a fee. Independent specialists and online services usually retrieve the same code faster.

Is the radio code the same as the security PIN?

Yes — the radio code, radio security code, anti-theft code and PIN all refer to the same four or five-digit number that unlocks the head unit after a power interruption.

Does a used car come with the code card?

It should, but private sales frequently result in the card being left with the previous keeper. If the card is absent, retrieving the code from the serial number is the most practical route.

Will the code ever change?

No. The code is permanently linked to the specific radio unit during manufacture and will not change unless the unit itself is replaced. A replacement unit will carry a different serial and therefore a different code.
