Can't help you with the fingerprint lock, but here is a keyless entry system that has worked well for me since 2011.  Not a single problem. Can be opened with the fob or manually with a key from the outside. Can be opened manually by turning a handle from the inside. The system I use is thoroughly explained in these two threads.
