You have a GREAT outlook on life (at least in regards to external car things)! I must comment on your comment @ ("My electric pump have 3-5 cm styrofoam base, I hope that will be no problem with water"). In this case nothing can prevent problems with your central locking module when water intrusion comes into contact with this module. I stand corrected, if you totally SEALED (which cannot be done) this part you can prevent moisture problems BUT you may have forgot this module relies on an air pump! A pump like this NEEDS an air intake, hence any sealing of the unit being impossible. Check for moisture/water there, too many have found out the longer it sits there, the more costly to fix!
It may be something else, but checking for this issue (which has caused far too many of the same problems you experience) is FREE! It could save you a lot of $ (in your funds). If that module is even slightly damaged, it could explain your problem. Water intrusion is a known problem with this component. Good luck!
