Toyota Yaris radio security code unlock instructions

This was god damned annoying, send your car for repair and now the radio is locked and only showing “SEC” on the screen. Apparently, this happens when the battery is disconnected. I was only able to find the instructions after alot of grief, pain and suffering and ALL THE OFFICIAL Toyota websites were USELESS >:XX

Sounds like you? Here’s how to enter the code.

Note: these instructions only apply to Toyota part no. PZQ60-12010, PZQ60-00021, PZQ60-0002 and PZQ60-52010

WARNING: you have a limited number of attempts to enter the code which according to the manual is 10. You can tell how many attempts you have used when you enter the incorrect code and it will say Err1 where the number 1 is the number of attempts so far. If a wrong pin code is entered for 10 times in succession, “HELP” will appear on the display window and will need to be sent to a Toyota dealer for assistance.

How to enter the pin number at the “SEC” display?

• Place the ignition switch to “ACC” position and make sure that the power source of the AUDIO system is turned off.

• Next, release all the other buttons then press and hold the Seek “^” button and push the Number 1 button. “_ _ _” will appear in the display window.

• You can now enter the numbers by push Number 1 button for the first digit, Number 2 button for the second digit and Number 3 button for the 3rd digit. Each time you press the button, the number for that digit gets incremented.

• After entering the pin number, you need to push the Scan button within 10 seconds to save it otherwise you will need to enter the pin number again.

Finding your pin number

Various sources on the web suggested the following “default” numbers set by the dealer if it is not provided with the documentation provided by the dealer.

• Last 3 digits of VIN number
• Last 3 digits of Chassis number
• First 3 digits of dealer code
