Security lite wont go off and have no power to anything except lightes door lochs and horn. I tried factory reset and still nothing

 

check the charging system. Does your battery show at least 12 volts?

 

When you mentioned trying factory reset and still nothing, are you referring to disconnecting the battery and then reconnecting it? Or are you referring to returning your car's ECM back to factory stock with a handheld programmer, as in SCT?

If you suspect that it's the battery, how old is it? if your battery is "OEM" Motorcraft and is over 3 years old and notice your radio is turning itself on and off, along with your lights flashing and active security system sounding the horn on and off? this usually means your battery is nearly completely discharged and requires replacement!
