Hi, as long as the sensors are intact, and the tire pressures are around 32-40psi. It should work ok after a reset.
If you don't have the i drive screen in the center of the dash, it is reset using the left turn signal stalk.
With the engine running, doors closed. Main menu in the cluster.
Use the thumb wheel to pull up the tire pressure icon.
Push the end stalk button once, it should say reset.
Push and hold it again until you see a check mark come up, its now initializing.

For the lock problem, this is common, and is likely a blown fuse, # 57.
The fuse panel is located behind the glove box. You need to remove the panel at the rear of the glove box by turning the fastener on either side.
There should be a fuse card on the back side of the panel.
There is also a red fuse puller stored on the fuse panel to make it easier to remove.
Replace the 15amp fuse with a 20amp one, and recheck operation. This is what bmw recommends per a service bulletin.

Operate the locks, and listen for abnormal noises at each door, if one is noisier than the rest, then that door latch will need to be replaced. It may blow the fuse again.
