I have a code lock, it's not wifi enabled but is opened with a 4 digit code. The nice thing is you dont need keys. It takes 4 AAA batteries and they need replacing once per year. Worth it if you always tend to lose keys (like me). Also handy if you have people coming into your place and they will be there temporarily (ie. cleaner) and need access but you dont want them to have their own key, you can easily change the lock code if needed
