Looking for an ERC Unlock Code List?

The short answer: a universal "unlock code list" covering every unit does not exist. Each unlock code is calculated one unit at a time from the 16-digit ERC code shown on the screen.

But you do not need to keep searching. If you have your unit's 16-digit code, you can calculate the unlock code right here, right now, for free.

How to Tell Which Generation You Have

Why Did It Lock?

When the unit loses power — a worn-out or replaced battery, removal of the audio unit, or a repair — the anti-theft protection activates and locks it. This is normal behavior, not a malfunction. It also happens on used or auction-bought cars when a security lock set by the previous owner is still active.

Also Called a "Password" or "PIN"

If your screen shows a password prompt, or you have seen it called a "PIN", a "security code" or an "unlock password", it is all the same ERC security lock. The 16-digit code shown on the screen is the ERC code; the 8-digit code calculated from it is the unlock code (the password). Instead of hunting for a list, calculating from your own 16-digit code is the reliable way — and on this site it is free and instant.
