Need code for radio bacause I change the battery and now radio dont work. can you help me please

I would check for a blown fuse probably located at the back of the radio. Or possibly in your fuse box.

Contact the manufacturer of radio

This code should be with manualy for car in the glove box and should be on a card the size of a credit card, also follow directions in manualy on how to install the code,take caution to enter code right bacause after three trys the radio will say loc which means your locked out. if code is not found then radio need to be remove to get serial # off the top, then call or go to dealer with serail # and proof of ownership and they can give you the code, i do thius all the time when customers dont have there code,

need to notify dealer radio codes are part of vehicle security most dealers dont charge for code but will need radio number ,vin number and usually are asked to come in with id

IF when you purchased your car you didn't set your own personal code you will have to take this to your local GM dealer and they can pull the code that is set at the factory and unlock your radio.THe proceedure for setting your own code then unlocking radio is in your owners manual.The dealership I worked for did this for free.

I have a Ford 5000 RDS-EON.
I need a KEY CODE.
The serial number: M344718.

Thanks a lot.

U will need to enter the radio anti theft code, this lock out was triggered by the loss of voltage to the radio during the battery change, this code is unique to each radio and cam in the owners information packet when the cat was sold new.

Hello There.

There are many websites that offer an unlocking service for a few £/$ . here is one that I found.
