Narrative:

Flying through the localizer and communication breakdown were two causes. In cases where it appears the plane will fly through the localizer; good communication goes a long way toward solving the problem. The localizer overshoot happened when approaching to land on 16L. After flying through the localizer; the first officer took controls and landed while I was turning back to the localizer.while enroute we were initially advised that we would land on 17R. Some time passed and our new runway assignment was 16L. We were assigned 8;000 feet; 210 knots and a heading to intercept the 16L localizer. The first officer extended the centerline and we maintained a heading to intercept. Later; the controller instructed us to proceed direct leets; and shortly after; cleared us for the visual 16L. I continued to fly using direct to leets with LNAV and autopilot. I verified with the first officer that we were cleared for the visual and instructed him to set 7;000 feet. I looked down to make sure we continued the descent as we had not yet reached 8;000 feet.as we approached the final approach course; I switched from LNAV to localizer; selected heading mode and pressed the approach mode button. At some point; I called for flaps 9; then gear down and flaps 22. I looked outside for a moment and realized we flew through the localizer. At that point; I disconnected the autopilot and started a turn back to the localizer. While initiating the turn; I felt that the controls were a little heavier than usual. At that point; I heard the first officer say he had the flight controls. When lined up on the runway; I told the first officer I would take the controls; but he did not agree. I was not going to argue about it so I let him land. This entire sequence took place with no localizer alive callouts and no callout to indicate we were crossing the localizer. The first I heard was 'I have the controls.' good communication would prevent this problem from ever happening.

Title: Regional airline Captain reported that after overshooting the localizer; the First Officer took control of the aircraft; would not relinquish control and continued to complete the landing.
