Kenwood 2 way radio help

Recently just bought two Kenwood radios from the pawn shop but they are locked on two channels they will not work with my other two radios anyone know why?

Hi James, we need more information. What are the model numbers of each radio? Are the Kenwood radios VHF or UHF? Are your other radios business or FRS/GMRS radios? We don’t have enough information for an answer, but based on what we have, it sounds like the Kenwood radios are programmed to completely different bands and/or frequencies than your other two radios.
