1989 260E alarm help

[tigeroscar1]

Hello all, Yes this is my first MB. I did a search about this and did not find what I needed.
Here is the problem, today I moved car and locked it with my key which armed the system alarm. Later on my wife open the doors with her keyless entry. Now the alarm goes off and will not stop. I'm not sure what she may have done other then use the remote then the key to disarm it. Super husband comes out and asks what's going on and she tells me the "whole" story. I try it too and nothing happens other than the alarm will not turn off. I get in and start it and it shuts off. Great I'm thinking but as soon as I open the door it goes off once again. Keyless entry is a no go the door lock & unlock with the key is also not working. I then open the hood and pull the fuze for the central locking system, it stops.
Now I try the system again to make sure it works after I reinstall the fuze and now the horn does not work, but the lights still falsh on and off. HELP

You might have a bad alarm switch in the driver door handle. Unlock the car from the passenger side or the trunk then see if it's back to how it was before using the remote. If that does it, don't lock the driver's door by key until you get the switches checked.

In the interim, locate the alarm control unit. I think it's under the almost vertical plastic panel in the passenger footwell. Look for a box maked 'Becker.' It'll have a couple of ~12 pin connectors. Detach the connectors to disable the alarm. The door locks and remote keyless entry should function normally with the alarm disconnected.

There's lots of info in the archives on getting keyless remote to work with the factory alarm system.
