Suzuki SX4 Radio Code — Unlock It Online

Your Suzuki SX4 is showing a CODE prompt and nothing else — a predictable consequence of any battery work on this popular crossover. Both the original SX4 I (GY/RW, 2006–2014) and the SX4 S-Cross II (2013–2021) use Panasonic or Pioneer OEM head units that lock on power loss and require a four or five-digit unlock code to resume normal operation. This guide covers the full process for both generations.

Why Does the SX4 Radio Lock?

Suzuki, like most manufacturers, programs its OEM audio units to activate a security PIN whenever the 12-volt supply is cut. The intention is anti-theft: a head unit removed from the car is worthless without the code. For routine battery maintenance, a flat battery, or a workshop service that required disconnection, the result is the same locked screen — but the solution takes only a few minutes.

Finding the Serial Number on a Suzuki SX4

Suzuki SX4 head units carry a serial printed on a sticker attached to the chassis. On some units the serial can be retrieved without removing the radio:

Button combination method: Switch the ignition to position II (accessories on). With the CODE prompt displayed, press and hold preset buttons 1 and 6 simultaneously for two to three seconds. The serial will scroll across the display on Panasonic-sourced units. Note down every character — the serial is typically eight to ten characters long.
Physical extraction: If the button combination does not display the serial, use trim removal tools or DIN extraction keys (depending on the fascia style) to extract the head unit. The sticker label is on the top or side of the unit. Pioneer units often require extraction as the button combination is less commonly supported.

Entering the Code in Your SX4

Ensure the ignition is on and the display shows CODE.
Press preset button 1 repeatedly until the first digit matches your code.
Use buttons 2, 3, and 4 for the second, third, and fourth digits respectively.
If your code has five digits, use button 5 for the final digit.
Once all digits are correctly displayed, press and hold OK or the seek (►I) button to confirm.
A brief confirmation message precedes the return to normal operation.

SX4 Generation and Radio Reference

Generation	Chassis	Years	Typical Head Unit	OEM Supplier	Serial Access
SX4 I	GY / RW	2006–2014	Single-DIN CD / MP3	Panasonic / Pioneer	Button combo or label
SX4 S-Cross II	JY	2013–2021	Double-DIN CD / touchscreen	Panasonic / Pioneer	Menu or label

The S-Cross II introduced a larger touchscreen head unit on higher trim levels. If your S-Cross is fitted with the optional touchscreen infotainment, the PIN entry may be done via an on-screen keypad rather than preset buttons. Navigate to Settings > System > Security within the touchscreen menu to access the PIN entry field. On standard (non-touchscreen) S-Cross units, the preset button method described above applies.

Troubleshooting Error States

CODE displayed: Standard locked state — follow the entry steps above.
WAIT: An incorrect code was entered. Wait 30 to 60 minutes with the ignition on before trying again.
ERR: Incorrect entry registered. Confirm the code before attempting again to avoid exhausting the available attempts.
Blank display after ignition on: Some units enter a deep sleep. Press the power button briefly to wake the unit, then wait for the CODE prompt before beginning entry.

Frequently Asked Questions

Is the SX4 radio the same as the one in the Suzuki Swift or Vitara?

Suzuki uses similar Panasonic and Pioneer OEM units across its range. The code system is the same, but each unit has a unique serial and therefore a unique code. A code from a Swift or Vitara will not work in your SX4 even if the radios look identical.

The button combination did not show the serial on my SX4 I — what next?

Try holding buttons 1 and 4 rather than 1 and 6 — early GY/RW models varied in this respect. If neither combination works, extract the unit using trim tools and read the label directly. The Panasonic label is usually clearly printed and easy to read once the unit is out.

My S-Cross II has a large touchscreen that does not show CODE — is it locked?

Some S-Cross II units with full infotainment systems boot normally after a battery change without a PIN prompt. If the audio works normally, no code is needed. If the system is partially locked or shows a PIN field, check the settings menu as described above, or consult a Suzuki dealer as some later units are VIN-paired.

How many wrong attempts before a lockout on the SX4?

Suzuki OEM radios of this era typically allow around ten incorrect entries before imposing a temporary lockout. The lockout period is usually 30 to 60 minutes. It is not permanent — verify your code before entering it and you will not need to worry about reaching the limit.
