Is this the factory radio?

You need to input the radio code to get it to play. Take it to the dealership parts counter and they can get it for free. It has a theft lock so if the battery is disconnected you need to input the code.

If the radio stopped working when you replaced the battery, there is probably a security code that must be entered into the radio to reset. This is done by the manufacturers to discourage theft of factory radios. If the lose power the lock and must be reset. Check the owners manual packet for an unlock code. If not there, contact a dealer for more help.

The reset code for your radio is located in the glove compartment. There should be a small sticker on the inside of the compartment door, usually near the left side. The sticker has two sets of numbers printed on it. The number set with five digits is your reset code. Use the radio preset buttons to input the code. If done correctly, the radio should come on immediately and show the factory default presets.

Positive feedback is greatly appreciated.

God Bless and good luck.

Good luck (remmeber comment and rated this).

theft lock is an electric code that keeps the radio from working if the power is disconnected you must reprogram your code to work again if theft lock is not programed by the owner it needs no code to work if you are going to replace it with an after market radio it is mute any way

the dealer is the only one that can unlock a locked radio, they will need to remove the radio, get a "code" off of the sticker on the back of it, and then call the dealers unlock assistance number to get an unlock code. it cant be done with out the dealer. im sorry :(

Yes so I would make sure you have the code from the factory at hand if you remove the power.

If you dont have it then you need to get it otherwise you will need a new radio face a return to factory cost

If the original factory code doesn't work, you need to pull out the radio and get the serial number on the side of it. Then contact the car dealer or the manufacturer and they would give you the code.

The code that you are referring to is also called the anti-theft code. This code is unique for each radio. No body could provide you the exact code except for the dealer or manufacturer.
