Echo car radio 37409 Security Code

[echoman0620]

I have owned my Echo from new but recently the battery died and now the Radio displays only SEC
I have looked in the manual but I'm unable to see the Security Code or any mention of a code.
I have tried the last 3 numbers of the Chassis number, but this didn't work.
Can anyone please help me.
My email address is ianandalisonm@hotmail.com
Thanks

The dealer you bought the car from was responsible for entering the codes for all the radios in cars they sold,chances are good that a call to that dealer will get that code for you probably at no charge,Due to internal security trying to guess the code will result in the radio shutting down for good after 5 unsuccessful tries.
