Does anyone know how this little thing can be "programmed" ? It looks like mine for some unknown reasons doesn't work anymore. I don't know if it is related to battery exchange or something else. To cut some issues, batteries in the key are new and checked. I have also checked it with second key. It just don't want to work anymore. I have heard that there is some kind of procedure to initialize the system. Of course it is all about S2 Coupe ABY. Of course central lock work fine when i turn the key. So the isue is most likely with IR only. Anyone can help?

C4 100/UrS4 Infrared Remote Key - Batteries and Reprogramming
Here is a C4 UrS IR key programming post that I have done on my home forum that might help you with your S2 with IR central locking:
"Reprogramming the infrared (IR) remote central locking key, if/when required, involves have one key in the ignition, turned to ON/RUN (but not START) while the second key is used to manually lock and unlock the drivers door lock. If the car has been sitting for some time or you have to change the batteries, getting the remote to work again just requires that you lock and unlock the door manually once and then the key remote will "work" again. (The IR remote has a very limited range and is intereferred with by bright sunlight and fluorescent lights (e.g. in a parking garage). HTH
Sometimes the issue isn't batteries but the little Item 29 infra red bulb:
