CODE IN is the factory security lock on Japanese-market Alpine head units — not a fault. It appears after a power interruption and simply means the unit is waiting for the correct security code. This guide explains why it appears, where to find your serial number and security data, and how the correct code is recovered — usually within 5–15 minutes.

Why does CODE IN appear on your Alpine?

The lock triggers whenever the unit loses power. The most common causes are:

  • Battery replacement or a strongly discharged battery
  • Battery terminal removal during maintenance or repair
  • Car electrical work that cuts power to the head unit
  • Prolonged lack of power, typical during shipping from Japan

Important: CODE IN is standard protection, not a malfunction. Alps Alpine owner documentation confirms that the security code protection engages after power is interrupted and clears only when the original code — tied to your unit’s serial number — is re-entered.

How do you find the Alpine radio security code?

There is no universal Alpine code — every unit’s code is calculated from its own security data. Entering random combinations only risks extending the lock. Depending on the model, the code is determined from:

  • The Alpine serial number
  • The radio model
  • The three security/secret numbers shown in the service menu (on supported models)

Service menu tip: on some Alpine models, the information menu opens directly from the CODE IN screen by pressing the upper corners of the display in sequence. The exact method varies by unit — never follow instructions written for a different Alpine model.

Where is the serial number on an Alpine head unit?

On the white manufacturer label stuck to the top or side metal casing of the unit. If the label is not accessible, the serial (or ERC identifier) appears on the lock screen on some firmware builds. On certain models, the service menu also displays the three security numbers needed for calculation.

What photos should you send?

Four clear photos are usually enough to identify everything required:

  1. The front of the radio (removed from the dashboard)
  2. The screen showing CODE IN
  3. The stickers with the model and serial number
  4. The service information screen, if available

With these photos, the model and required data can be confirmed within minutes — no dealer visit required.

Why you shouldn’t enter random codes

The security system is paired to the specific device, so guessing never works. Random entries can extend the lock and waste hours. The reliable path is to identify the model and security data first — then obtain the factory-calculated code.

Real recovery example — Toyota Vellfire (Alpine EX009V / EX008V)

A Toyota Vellfire imported from Japan showed CODE IN after a battery change, with no code documents. The security data was recovered using information from the unit itself — no disassembly, no dealer visit — and the owner received a working code the same day.

FAQ

Can the Alpine code be recovered remotely?

Yes — in most cases the radio never needs to be removed. If the service information is accessible, a photo of the screen is enough; otherwise, a photo of the serial-number sticker works.

How long does the recovery take?

Codes are delivered within 5–15 minutes, 24/7. Every code is backed by a 100% money-back working guarantee.

What if CODE IN appears after every battery change?

That is normal — the lock re-engages after each power loss. Keep your recovered code safe; the same code works every time because it is permanently tied to your unit’s serial number.
