Opel Corsa B doors

Hello everyone. My problem is that a few days ago I can not open the doors of my Opel Corsa B of the year 94. The alarm has been connected but it is not deactivated so if I force the doors to open them the alarm sounds and the anti -theft system does not let me start the engine. I can tell me if the same thing has happened. I have changed the microchip of the door and continues to fail.

To deactivate it you have to look for the engine blocking that can be connected to the starting or lighting system or the fuel feed system once you find it apart to disconnect the alarm feed and where the reliever is connected if it is 5 contacts you have to look for one 4 normally closed by k the 5 legs is the K has two contacts which one connects to the horn and the engine is closed Of your help for k Asino you will have to change the complete alrma system in a specialisted place
