build a door alarm

Then I suggest you search BMW or electronics forums. the12volt deals with things like car electrics & accessories, and wiring and interfacing methodologies. It does not deal with electronic circuitry and sound kits etc - it would only deal with how to connect those circuits. A BMW site should be able to tell you what module creates that sound. You might then be able to obtain that module. Electronic and audio-project sites may have circuits that can replicate the sound. Or maybe buy or build a digital recorder or sampler and use that.

Thanks to my friend I do not know English, you can do it for me

I can do English, French, Spanish, some German, Hebrew and a little Arabic. But not Farsi.

Thank you

I still suggest including you original Farsi text. Readers may have their other translators - eg, the firefox Translate This add-on I mentioned. Besides, there may be Farsi speakers. We certainly have many down-under here, but I don't know if they'd be on forums. Good luck and best wishes.

The nearest places you will find the parts and expertise will be either Israel or India.

Search I I can not find the Israel Says Iran Sanctions No one will help me
