Hello My name isXXXXX will be glad to assist you today in answering your questions.
The locks working is good, but the central locking module was damaged from the flood, if the keys wont reprogram module is bad. Air bag module should be under the center console that was also damaged I would check for a used one for you vehicle just make sure the part numbers match exactly.
The central locking mechanism still works when using the drivers door switch however not when using the remote on the keys. Where is the module/console located that you propose may be damaged? Thanks
