Centralized Citoren Xara Closing

Hi how are things.

I have an Xara HDI of 2004 and the remote control does not open or close the car, pile it has and emit if I emit because I have led it to check. When closing with the key, it closes all the doors and the look that this closed is turned on well. If so, anyone knows how you can program again or do you have to take it home?

Thanks in advance for your help

To start a term of 1 minute to the battery, put it and leave the command tight. You will tell me
