Radio code Hyundai i30 II

A flat battery after a long winter lay-up or a battery swap at a garage — and suddenly your Hyundai i30 II's radio shows "CODE" on the display. In its generation the i30 II was one of the best-selling family compacts in Europe, and the Mobis radio inside it has an anti-theft protection that still activates today. Here's how to clear that message quickly.

The i30 II (2012–2017) has a Hyundai Mobis OEM radio in every version. Mobis (formerly part of MANDO, now Hyundai Mobis) is the exclusive radio supplier for all Kia and Hyundai models from this period. The radio is immediately recognisable by its brand-specific look and its compact single-DIN or double-DIN housing, depending on the trim level.

Some i30 II versions came with a navigation system — that too is a Mobis unit, but larger (double DIN) and with a touchscreen. The navigation version also requires a code.

Exception: i30 II models with the optional Hyundai Blue Link connectivity module (available on higher trims, 2015–2017) sometimes don't have a traditional code. This is rare in the European market, however.

When the i30 II was originally delivered, there may have been a code card in the document folder. Hyundai didn't always supply this as standard, but dealers sometimes added it themselves.

Look here:

The i30 II has a centre-console design in which the radio is surrounded by a trim panel. Removal usually takes five to ten minutes.

Tools

• Plastic trim lever (pry tool)
• PH2 Phillips screwdriver
• Torx T20 bits

Step by step

The Mobis OEM serial number is on a label on the back or side of the radio unit. It's alphanumeric, 10 to 16 characters long. There's no fixed prefix.

What you'll need:

• The full serial number for an online code request.
• Specifically the last four digits if you want to try the 1212 formula (see below).

Tips

• Take a photo of the label — it's easier than copying it out on the spot.
• The characters are sometimes small. Use your phone's flash for extra light in the dark space behind the dashboard.
• The radio's model number (e.g. RCD-350) is not the same as the serial number. You need the alphanumeric string, not the model name.

Just as with Kia models, there's a well-known calculation formula in circulation for the Hyundai i30 II:

Formula: Take the last 4 digits of the serial number and add 1212. The result is possibly the radio code.

Example: Serial number ends in ...2105 → 2105 + 1212 = 3317

Warning: The formula works on around 60 to 70% of the older Mobis units. On the i30 II — built from 2012 to 2017 — the reliability varies, depending on the exact type of Mobis unit. Only use the formula if you've already removed the radio (and therefore have the serial number anyway) and want to save on an online request.

If you only have one or two attempts left (after earlier incorrect attempts), request the code safely using the serial number.

The entry procedure for the Mobis OEM radio:

After three to five incorrect entry attempts the Mobis radio locks for 30 to 60 minutes. With repeated lockouts some units can activate a permanent lock that can only be reset by a dealer.

How to clear the temporary lockout:

The i30 I (2007–2011) has a mixed situation — some versions don't require a code. The i30 II (2012–2017) almost always requires a code. The i30 III (2017–present) also requires a code in standard versions; higher trims with Bluelink or CarPlay integration don't.

With the serial number of your Mobis OEM radio you can request the code directly online. Enter the serial number on RadioCodeOpvragen.nl and receive the code by email within minutes.
