I have a 2000 Nissan sentra Gxe and the OEM alarm remote system does not work. Also The interior lights, and power door locks don't work either. The remote does not activate any system at all. The remote covers the trunk, locks, security, flashing lights and horn. I have checked all the fuses inside and engine compartment and there all good. Could this be a Security module problem?? How do I test w/ my ohm meter.

Thanks again, Mahalo Sam.

i bet you your rear defogger dont work either?!?! its a 10amp fuse under your hood i think its the one for the..damn i cant remember which one. but its under the hood next to the battery check all of those fuses. i had the same problem and it pissed me off for 2 months and it was a damn 10 amp fuse.
