SEAT Leon, Ibiza and Altea radio code: how to find and enter it

SEAT factory radios in the Leon, Ibiza and Altea of the 2000s and early 2010s use the same 4-digit anti-theft code as other VW Group radios.

Is this your radio?

Factory SEAT radios have a serial starting SEZ on the label. Newer touchscreen systems in the Leon Mk3 and Ibiza 6F are MIB units and don't use a code.

Commonly fitted to the Leon Mk1 and Mk2, Ibiza 6L and 6J, Altea, Toledo Mk3 and Alhambra Mk1, with factory CD radios and pre-MIB Media System units. Exact fitment varies by year and trim.

Step 1: find the SEZ serial

The code is tied to the radio's serial number, printed on a label on the radio's casing. It's 14 characters and starts with SEZ, for example SEZ1Z2A1234567. Don't use the part number, which starts with digits.

To read it, slide the radio out of the dash. Most units come out with radio release keys; some are held by Torx T20 screws behind a trim panel. There's no need to unplug it. More detail: where to find your radio serial number.

Step 2: get the code

First check the service book wallet for a radio code card whose serial matches your radio. If there isn't one, you can order the code from the serial: £24.99, delivered by email in 1–3 hours on average.

Step 3: enter the code

1. Switch the ignition on and the radio on. The display shows SAFE, then usually 1000 or 0000.
2. Set each digit with preset buttons 1–4. Button 1 changes the first digit, button 2 the second, and so on. Each press counts up by one, and 9 wraps round to 0. Read the starting display carefully: if it starts at 1000, the first digit already shows 1.
3. Confirm by holding the accept button for 2–3 seconds until the radio plays. This is usually OK, SCAN or the right seek arrow.

Our Workshop Manual has a press-count planner that tells you exactly how many presses each button needs.

SEAT Media System units with a screen show an "Enter code" or padlock prompt instead: tap the four digits and press OK, with the engine running so the unit doesn't power down.
