I just thought about this just now. What if I somehow lost my keyless entry Fob somewhere in a parking lot and never found it. Obviously someone might pick it up and go to every maxima they see to try to open up the car that it belongs to. I would guess that replacing the keyless entry with a new one will change the code or is it the other way around? does the car programs the keyless or does the keyless change the car code?

 

If I'm not mistaken, each remote has a fixed code. Your BCM (Body Control Module) can store a maximum of 4 codes.

When you reprogram your keyless system, you are teaching the new codes to the BCM. BCM will store new codes, keyless code will stay the same.

 

get an aftermarket lcd alarm/starter they cant unlock the doors without a password they must enter into the lcd remote!! im shopping for one now. here a few systems ive been looking at:

the aladdin 2000, by far has the coolest looking remote!




autopage RS-750LCD, coolest function is that the cabin temperature is always displayed on the lcd screen!




compustar 2wSS, its color!




i havent decided which one im going to buy yet. theyre all really cool. oh, the lcd alarm can also be paired with a starter, like in these models. the car will start at any time you specify. like... 10 mintues before you walk out the door for work, etc.
