The only issue I can see not being able to re-key is if a portable or mobile loses it key. I would take a lot of smarts to break the key. And what does WPS have/do that is so sensitive that they would need to change keys?Hemi204 said:Actually its due to poor service and lack of reception in certain areas of the city. Its become a safety concern! maybe the fact that they cant re-key the radios over the air has something to do with it also..
