Tone locks (CTCSS and DCS for the interested) are ways of effectively making a radio only emit audio for transmissions with that tone lock rather than anything on that frequency that hits the transciever. Because of how cramped the airwaves can be, it's a useful feature for analogue. Scanners don't "recognise" tone locks because the signal is still on that frequency.

It'd be best to ask Cadwell directly as they can be the ones to make the decision as to whether they want to release the tone lock or not.
