Sony model #CDX-M630 car stereo reciever

I installed a new battery in my recently purchased used vehicle and now the car stereo keeps giving me a "CODE IN" flashing on the console. I do not have the code to input into the reciever, is there a way to reset it or obtain the proper code to get the unit to work. Thanks, Joe Holdridge

    I do not have the code to input into the reciever and also do not have the remote, is there a way to reset it or obtain the proper code to get the unit to work and also is there any way to insert the code without remote.

I need a code for Ford Laser 2003 radio


Go online. Here in Europe there are endless online companies who will give you the code if you give them the make and model/serial number etc of your radio. Just sweep the web for "Radio code suppliers" and for a couple of bucks they give you the code.
For next time, write the code in the owners handbook in the back or so or connect a small 12v battery(Lawn mower/Quad bike?) to the 2 batt leads with croc clips so it keep the system alive when the main vehicle battery is removed.

Tailights,Dashboard Lights Fuse Keeps Blowing Out


One thing to check and I have come across this a couple of times is that some factory stereos used a black wire for the stereo illumination, if you have wired the black (earth) from the new unit to this wire it will cause the fuse to blow, disconnect the earth from this wire and wire it directly to the vehicle.

Sony xav-622 security code


The code that the car stereo AV center is looking for is a 4-digit security code that is programmed into your system during the installation process. This code is generally needed when one of the following issues occurs on the car stereo:
  • the AV center was reset.
  • the screen locks up on the unit.
If you purchased the vehicle from an individual, contact the seller of the car to see if they can give you the code. If you had your AV center professionally installed, we recommend that you contact the installer to see if they are able to provide you with the code.
If the seller of the vehicle or the installer is not able to assist you, or if you installed the system yourself, please contact the Customer Experience Center at (239) 768-7547 to speak with a customer service representative.

Recently i have the battery check on my uncle's explorer 2006 but after that the car radio/stereo is asking for a code, what do i do now?


you'll need to go to the dealer
they will have the tools to access the code from the vehicles computer

assuming your uncle is the original owner and he still has the owners manual and folder that came with the vehicle then the code should be on a tag there


good luck and keep us posted

I have a stereo of Cavalier 2002 but it shows ''LOC'' in the display. Can somebody help me to clear this lock. What could be bad on it?


your stereo is locked. your battery drained and clock memory was lost to radio. a simple fix can be found on this forum but they charge 4.99 or so to help. they dealer will cost 50 + so 5 bucks is worthit.

i am sorry you had to go threw this. positive side you will have the code so it will not be a problem in the future for you.

they radios of modern cars employ so called anti theft mechanisms, but in reality they are designed to cost us money to get things working normal again. this is by the way the only device on your car that is lockable by the power failure

good luck with it. and a little tip: they sell a 9 volt battery maintainer used by professional stereo installers to keep clock memory voltage on the radio so this doesn't happen when you need to disconnect your battery again. i would highly suggest getting one. they are fairly cheap and will prvent you from having any major issues in the future when you need to replace or disconnect your cars battery again.

Not unless it was written down in there by the oridginal purchaser so you will have to write VIN# down and phone the dealer and they will be able to give you the code along with how to do this also it must be a factory sterio hope this helps
