Leaving door unattended

[FatimaBegum]

Hey,

I own a semi-detached house in London with an L2000 Rim Deadbolt door lock system. I want to know whether there are any door lock systems or alarm that goes off when the key is left in the door? Kindly would you recommend a reliable company that provides a similar product.

Regards,

Fatima

That is a Banham product, so you should ask them.

I have not heard of a device that does what you suggest.

What triggered your need?
