Hello and welcome to jeepz.com
I'm not actually familiar with that model year but it sounds like the security light is the light in question . If that is in fact the case , the key is supposed to be programmed to be recognized by the security system . Only the dealer or a qualified locksmith that does automotive lock cylinders can do that . I'm assuming that you've got no issues starting the engine and all else is well with no drivability issues ? I ask because on newer models , if a key isn't recognized by the security , the vehicle either won't start ( or even crank ) or stall to prevent theft . If you can find out what symbol the light is displaying , that may be helpful . You might even find it in an owners manual if it's still on board . If you can post a picture that can clearly illustrate it with any message the light may have would be helpful too. Hopefully someone here will have knowledge of this light .
