Creating A Device With Configurable Security Pins

Hi All

Does anyone know if its possible to create a device with configurable pins that can only be turned on once the correct pin has been entered?

I have been looking for a suitable door lock that suits our two door front entry doors and that also comes with blanks to suit handles on both doors / sides but all suppliers I have spoken to advise blanks are not available and I’d have to purchase two locks.

To avoid this I am looking at installing a simple 12v electric door strike in one of the doors and have it powered by a 12v transformer momentarily powered by a z-wave appliance module.

BUT

I only want people who know a pin code to be able to unlock the door / activate the module and get inside.

If a plugin or device could be created that supports the use of security pins this would resolve my issue.

Thanks
