remote starters

id like to no if a remote starter would work on a 04 nissan sentra the reason i ask they have a chip in the ignition key

well......if that "chip" thing is for real,
then the engine wouldn't start without the key,
so no, remote starter wouldn't work.

btw, take care of your keys, it costs about
$180~$250 for a new key

I believe some remote starters are programmable to send the same signals as the keys would. Obviously, only the more expensive ones can do that though.

Anything is doable these days, I charge around $ 200.00 to get one done, there are bypasses that you can use with out doing anything to you Key/Alarm system, keep everything original,
