THe built-in security code in my Marantz 701 was triggered, and the car dealer idiots did not enter the code. Now the radio is brain dead. I have the code. How can we resuscitate it? It is a Marantz 701

Can you reply to my email? I'm not sure i'll ever find this website again.

My car radio DOESN'T WORK ,I HAVE A FAVOURITE CD STUCK INSIDE , HOW DO I FIX THIS PLEASE ?


Sounds like a programming issue with security... You may have a weak car battery and when you started the car there may have been a momentary significant dip in the voltage to the radio as the engine used most of the juice to get started. The radio thinks it was trying to be removed or disconnected and triggered a security lock. I you know how to unlock it with the given code or procedure do so, or you may have to have it serviced and unlocked by a dealer.

No one has your security code for a radio or any other item

Ask a dealer how to go about that

Why doesn't clock and radio work after installation of new battery?


Enter security code, it is in your owners manual within first few pages. It is written in by tech who checked vehicle out before delivery of vehicle. If no manual you will need to bring it in to dealer so they can look up code.

Radio code


  • The 4-digit code for your radio is listed on the two radio security cards supplied with the vehicle.
  • Enter the code by using the pre-set buttons numbered 1 to 6 and a "beep sound" occurs.
  • If the code is not properly entered, then begin the code entry again, starting with the first digit. If the code is not properly entered in three successive attempts the radio will not accept any entry until the radio has been left on for one hour (the radio display will show the word 'WAIT'). After one hour in the 'on' position the radio will accept three additional entries.

Note: Should you lose your radio security cards, contact your Jaguar Dealer, who for security reasons will require proof of vehicle ownership.

I hope this info helps!

SEC appears on the radio Lexus ES300


SEC stands for security, the radio is in theft lock you must enter the unique code security that came with the car when new to unlock the radio, this SEC is triggered whenever the radio losses power like a theft or a battery disconnect. If you don't have this unique code you must see the Lexus dealer, they can look it up in the factory information link, it goes by the serial number of the radio and the VIN or the car.
