Could the new sensor be bad as well? any input would be helpful. best
Assuming the meter is connected and set to measure resistance correctly, then ... either both your sensors are bad (not impossible, but does seem unlikely) or the magnet you tested with isn't strong enough to close the reed switch.

I'd make sure the magnet is powerful enough to operate the sensor (eg not a fridge magnet).

Maybe you have a magnetic tool dish, tool shelf or power strip? Or an inspection light with a magnetic base? These tend to have quite powerful magnets... Or a rare earth super magnet, rated to hold 400 lbs for magnetic "fishing", is about $10 on Flea Bay.

If a strong magnet won't close the sensor, the sensor doesn't work.
