Key is stuck and car shows two gears at once

Welcome to 2CarPros.

What I suggest is first confirm the cable is properly adjusted. I'm not sure what was done when it was taken apart, but if the cable adjustment changed, it can cause the issue.

Here are the directions for adjustment. The attached pictures correlate with the directions

ADJUSTMENT

WARNING: Make sure lifts are placed properly.

1. Remove the front console.

2. Shift to [N] position, then remove the lock pin from the adjuster.

3. Check that the hole in the adjuster is perfectly aligned with the hole in the shift cable. There are two holes in the adjuster. They are positioned 90, apart to allow cable adjustment in 1/4 turn increments.
4. If the hole is not perfectly aligned, loosen the locknut on the adjuster and adjust as required.
5. Tighten the locknut to 7 Nm (5 ft. Lbs.).
6. Install the lock pin on the adjuster. If you feel the lock pin binding as you reinstall it, the cable is still out of adjustment and must be readjusted.
7. Make sure the lock pin is seated in the adjuster securely.
8. Move the shift lever to each gear, and verify that the shift position indicator follows the automatic transaxle gear position switch.
9. Start the engine, and check the shift lever in all gears. If any gear does not work properly, refer to troubleshooting.
10. Insert the ignition key into the key cylinder on the A/T gear position indicator panel, and verify that the shift lock lever is released.

Let me know what you find.
