Clio wont lock

So recently my battery went flat because it's been stood for about a month. I got it jump started, put in the radio code and got everything else working. Just now the doors won't lock. I've read on some places that you have to reset the key somehow with ignition and then I've also read things such as opening all the doors and the boot and leaving them open with the key in the ignition for 10 minutes.

PLEASE SOMEBODY HELP!!!
