DO NOT MOVE until it achieves lock.

Every time I walk out of my house and try to get a lock while walking it takes up to 10 minutes to lock.

If I set it on my porch while I put on my coat it locks in a minute if it's not been "moved" a long distance.

Example of long distance, drove 200 miles with it off, it took a loooong time to lock on next morning.

Example of short time - last used two days ago, put it on my porch at 0952, achieved lock by 0953.
