Remote access locks for maintenance access

[Marvin Meng]

I'm interested in switching to keyless entry locks that can be opened remotely. All I'm finding are web-based, which would run off of the house's (tenant's) wifi. Do any of you use this and how well does it work? Are the cell-based phones that don't require the house's wifi? I'm mainly interested in being able to let in maintenance and cleaning people when I can't be there.

Thanks!
