Install a smart lock on a bedroom door or keep it keyed?

[Bruce P.]

Hi,

So I'm getting started renting out rooms. I'm thinking to make one an Airbnb and the other a long term rental. In either case, I think it might be a nice amenity for a guest to have a lock on their door to "feel safe".

1) Should I use smart locks on all the bedroom doors (keyless) or use a different keyed lock on each bedroom door?

2) If you think "yes" for smart locks, what do you think of this smart lock - https://www.amazon.com/Advanced-Security-TurboLock-Keyless-Keypad/dp/B06WW2HHZC/ref=asc_df_B06WW2HHZC/ ?  The main feature it has that I like is a "master code" (for an owner) and then custom codes for the tenant. I'm looking for one that allows me to program the locks from the comfort of my computer which I imagine must exist.  But I'm also trying to be conservative with money.

3) If you think "no" for smart locks, what kind of keyed lock(s) should I get?

Does anyone have any other suggestions?
