Customer Question

I purchased and old car 3 years ago and it had a 3DE-7887 FM/AM In -Dash CD Changer Receiver.
I kid was touching the front plate and it popped off. Now I can not get the radio back on. And I don't have the manual. Is there a code for it so it will turn back on or what do I do?
Thank you,

Hi, thank you for contacting My name is***** will do my best to provide the right answer to your question.That removal of the front plate may have cut off the power by an interlock or some such, perhaps. (Do you have any difficulty fitting the removed front plate back on again? if so, give it priority before the following - since, if having the front plate off removed power from the unit, you won't be able to turn it On, much less cure the other problem(s) if any.) The removal of power, if that's what happened, might have activated an anti-theft feature. An activation code for a car radio or car stereo etc., is an anti-theft feature. When the device is removed from the car, the battery power is interrupted to it, and this activates the anti-theft feature. The entering of an obscure code is required before one may use the radio or stereo etc. again. Sometimes this anti-theft feature is activated when no theft is involved, for instance:- when a car stereo is sold, after being taken out of a car, by its legitimate owner.- when a car's battery has been disconnected for servicing of various sorts or in the event of car battery failure. The code is very hard to 'generate' or hard to find. It would not be an effective anti-theft deterrent otherwise. I have not the means to generate the code for you (though I believe it is generated from the serial # ***** the device and according to the maker and model.) I advise that you take the car to a dealership for that brand (the car's brand that is), and have them generate and enter the code for your stereo.
