Default Circuit diagram of garage door remote control

I own a Einhell garage door opener with remote control
It does not work anymore. It is transmitting continuously. Inside the
cabinet there is a microswitch that is operated by the battery door. When
this one is activated it starts transmitting and does not stop anymore.
Without a circuit diagram and part numbers removed from the two IC's on the
board it is very hard to find the problem.

Does anyone have a circuit diagram??

Type MS 433
Art-Nr 16.602.00
