A Security Code Bug in Some Kenwoods

There is a reported bug in the security code handling of some Kenwood stereos. In models with the bug, the security code is stored incorrectly. The workaround is to enter the wrong security code.

In models with this bug, decrement the third character of the security code by one. For example, if the security code is 1111, enter it as 1101. If the security code is 9999, enter 9989.
