You need a code, which would have been programmed in when it was installed/last serviced by the fitter.
No idea about Siemens, but on the Honeywells with that feature, there is no way of resetting the PIN number, if you've lost the number, it's a new programmer.
As yours is carrying on working, it shouldnt be a problem, they can be set to turn off, and not come back on again, if that happens, you are stuffed, so new programmer again.

A Megger will usually fix problems like this.
