Radio is asking for a CODE- I have the number for the code but when i put the number in, nothing happens.

ask ford to fix it, they can
the car came new with card in the glove box
said. "this is your radio code. keep it in a safe place"
lost that?
if yes ask ford for the code. (license serial code)
or google for hackers and pay.

this happens with the cars main battery is dead or was disconnected

if I remember rightly you take the first button and press it the number of times in the code (code example 6152)
so first button press 6 times
next button press once
next button press 5 times
next button press 2 times
there is a site that explains how to enter codes
go google and type in -- how to enter codes for ( what ever you are putting codes in)

Did you happen to disconnect the battery for some reason? If so, all you should need to do is call the Chevy Dealer and talk to the parts department. Explain to them that you need the code to unlock your radio. They will probably ask you for the VIN number. This is what happened to me when I put the stock radio back into my Saturn. The dealer gave me the number and it worked. I hope this helps you!

Contact the dealership with the number (assuming this is the number that came off the radio itself) and they will give you an unlocking number (preferably where the car was purchased) and ask them what the code is and how to put the unlocking code in or you can refer to the book with the number the dealership gives you. If that doesn't work they might have given you the wrong number (which happened to me thats why I am telling you this) call them back if that happens. All Acura radios have their own code none are alike. It should work immediately once you put the code in but I believe you have 4 or 5 chances to do this. Be sure to keep the numbers in a safe place in case this happens again or if you sell the car and tell the next owner about this. Good Luck!

You have to find the correct code entry instructions for your radio.

This will depend on the radio make + model

Disconnect the negative terminal on your battery and reconnect after 10 seocnds. That should reset the radio and you can enter the code.

The serial number may be on the back of the ash tray. Take that serial number and call Acura dealership - they will give you a code. I got a new battery and the same thing happened - needed a code. The serial number is on the back of the radio but the original owner was nice enough to put the sticker on the back of the ashtray. Some times, people put it on the inside lid of the fuse box.

either the radio code is wrong or you have locked the radio down you only have three attempts to enter the correct code if this is the case disconnect thenegative battery cable for 10 minutes then reconnect and try again. If the code is wrong the audio unit will have to be removed so you can get the serial number to give to the honda dealership so they can get the correct code

Your radio is now in "off" mode. To get it back to "code" mode you need to have power to the radio for 2 hours. This can be accomplished by either driving the car for 2 hours, or putting the key into position 1 on the ignition, but make sure to turn off the fan as it will drain the battery in 2 hours. Once you have "code" back you can enter the 4 digit radio code. Caution, many of these radios have been replaced so the code that the dealer gives you may be wrong. If entered and it comes back "EEEEEE" that means it is the wrong code. The radio must be pulled and get the factory serial number from the top of the unit.

Hope this helps!

look in your glovebox and see if you have one of these cards. they come with every new mitsubishi.
if not you'll need to pull out the radio and take it to the service department at your local mitsubishi dealership. they will enter the serial number off the sticker on radio into their computer and give you the unlock code.
