smart door knob/lock to allow maintenance into rental when tenant is not home.

[Chris M.]

Working with my last tenant to allow people into the apartment to fix things was a nightmare.  I am thinknig of installing a smart door knob and lock so I or the tenant can program temporary codes to allow access when someone needs to show up to fix something.  Anyone ever done this?  Not sure how a tenant would like this.  I am pretty lax about stuff like this; it wouldn't bother me.  Any apartment has maintenance people showing up when you're not there to fix stuff.

I would want the tenant home or me be present when maintenance is there.

Too much liability for letting maintenance in with no witness.

Tenant could claim stuff was stolen and you couldn't prove otherwise.
