mga masters I need your help.

been lurking on this forum for a while and i've learned a lot from your collective wisdom to the point that akala ng mekaniko marami ako alam sa kotse.

that aside, merom po kasi kami used car na binili (auctioned by a bank) that used to have an alarm (i think). the key came with a remote. meron din po blue LED sa dash na nag bi blink pag naka sara na kotse. wala po sya siren (yun ba tawag don? o speaker?). I looked under the dash, meron din po siya parang push button switch na dangling.

the keyless entry is not working dahil sira po yung driver door actuator (parang gun-type). Central locking is ok.

questions ko po:
1. ano po ang functions ng keys na nasa remote, (link to picture below).
2. paano po ba i-off ang alarm na silent naman, lagi lang nagbiblink at kumakain lang ng batt power. baka po kasi ma disconnect ko rin ang central locking e.
3. meron po ba mabibili na speaker lang at yung actuator?

pasensya na po for being long-winded. your help will mean a lot. salamat po.
