About SEAT radio codes
SEAT’s radios in the Ibiza, Leon, Altea, Toledo and Alhambra – the Alana, Aura and Adagio, the later SEAT media radios, RCD-type radios and RNS sat navs – use a 14-character serial starting SEZ. That lasted until the Media System touchscreens, from 2012 on the Leon and about 2016 on the Ibiza.
Alana, Aura and Adagio: where the SEZ serial is
The radio’s name is on its front, but the serial isn’t shown on the screen. SEAT supplied a code card with the car, so look in the wallet first: if the card is there, nothing has to come out.
Otherwise the radio does. The slim radios need two release keys, and the taller media and sat nav radios four, including the double-height radio in the Mk2 Leon. Our step-by-step removal guide shows where they go.
Two numbers on a SEAT label
SEAT labels carry a part number as well as the serial, and it is easy to pick the wrong one. The serial is the one starting SEZ, with 11 more letters and numbers after it, like SEZ1Z4B2646976. Type all 14, including the SEZ.
Photograph the label rather than copying it out: on these serials an O is a letter, and it looks a lot like a zero.
Media System SEATs
The Media System touchscreens in the Leon from 2012 and the Ibiza from about 2016 are matched to the car rather than locked with a code. There is nothing to type in and nothing to work out from a serial. A SEAT dealer can match one.
SEZ codes come from code lists
SEAT codes work the same way as VW ones: each was set at the factory against the serial, and it can only be looked up, never calculated. We hold many SEZ serials, but not all, and the free check says which before you pay.
A SEAT dealer can often look a code up too, with the logbook (V5C) and ID, but only for the radio the car left the factory with.
How to find your SEAT radio serial number
The serial isn’t shown on the screen: it is printed on a label on the radio itself. The serial tells us exactly which code your radio needs.
On the label
- Check the radio card in the handbook wallet first.
- Otherwise take the radio out with radio removal keys.
- Copy the serial from the label: 14 letters and numbers starting VWZ, AUZ, SKZ or SEZ.
Photograph the label rather than copying it by hand — 0 and O, 1 and I are easy to mix up.
Most radios slide out with a pair of radio removal keys (a few pounds from any car parts shop). Push them into the slots on the front until they click, then ease the radio forward. Some have screws to undo first.

How to enter your SEAT radio code
Once you have your code, key it in like this. Your order page shows the same steps next to your code.
VW group (Beta, Gamma, RCD, Concert…)
- Buttons 1 to 4 set each number (press again to count up).
- Hold one of the arrow (seek) buttons for 2 seconds or more to finish.
If your SEAT radio says LOCKED, WAIT or SAFE
Each wrong code makes the radio wait longer before the next try, and some radios lock for good after too many. Don’t guess: get the right code first, then follow the steps for your radio.
| Radio | What to do |
|---|---|
| VW group (Beta, Gamma, RCD, Concert…) | SAFE — leave the radio on for 1 hour (the ignition must stay on), then try again. |

Why we use your radio’s serial, not your number plate
A radio code belongs to the radio, not the car. A dealer usually looks it up from the SEAT’s number plate or VIN (the 17-character number in your logbook), which only works if the car still has the radio it left the factory with. Radios are often swapped under warranty, upgraded, or changed by a previous owner.
The serial is printed on the radio itself, so the code matches the radio in front of you. It is also what lets us check for free before you pay. Main dealers often charge £30–£130, and you usually have to book the car in.
What we can and can’t do
We can do
- Alana, Aura and Adagio, and the later SEAT media radios
- RCD-type radios and RNS sat navs with an SEZ serial
- SEZ serials that are in our code lists
We can’t do (yet)
- Media System touchscreens (Leon from 2012, Ibiza from about 2016)
- SEZ serials that aren’t in our code lists — the free check tells you before you pay
We always tell you before you pay. Not sure? Send us a photo of the label.
SEAT radio code questions
Which number on my SEAT radio label is the serial?
The one starting SEZ, 14 characters in all. The other long number is a part number, which is the same on every radio of that type.
Can you do the radio in a SEAT Leon Mk2?
Yes, if its serial starts SEZ and is in our code lists. It is a double-height radio, so it comes out with four keys.
My SEAT has a Media System touchscreen. Do I need a code?
No. Those are matched to the car, so there is no code to type. A SEAT dealer can help if it needs matching again.
Does a SEAT radio use the same kind of code as a VW?
Yes. SEAT, VW, Audi and Škoda radios share one code system, with a different first three letters on the serial. Each radio still has its own code.
Where is the code card for my SEAT radio?
In the wallet with the handbook, if it is still there. It shows the radio’s serial and often the code, but it only matches the radio the car left the factory with.
How much is a SEAT radio code?
£9.99 per code. The free check comes first, so you only pay once we know we can do it, and you get your money back if the code doesn’t work.
How long does it take?
Most SEAT codes appear on screen the moment you’ve paid, and we email you a copy. If yours has to be looked up by our team, we email it within 2 hours and tell you before you pay.
What if the code doesn’t work?
Check the serial first: 0 and O, or 1 and I, are easy to mix up. Still stuck? Tell us from your order page and we’ll put it right or refund you in full.
