i have a sds-100. Recently the function knob is acting up. When you rotate it one click it jumps two or three. I have the ext warranty through bearcat warehouse where i purhcased it in April 2021. They agreed to replace it. My question is i purchased the DMR and NXDN upgrades directly from uniden. Will my keys work in a new SDS-100 scanner or does anyone know if uniden will give me free new keys to load in. I do not want to spend another $110 on upgrades
