Moreover, there are smart locks available that attach to the inside of your door and are designed to use your existing keyed cylinder and deadbolt hardware, which means you only need to remove the escutcheon.

But for the other ones, the best option is, buying from the intermediaries who import products from Amazon, Gearbest and other reputed global e-commerce sites. Some gadget shops also import door locks on request, you can use that option too.

Since smart door lock technology is relatively new and yet to be widely popular, we cannot say that this system is for everyone, at least for now. But we firmly believe that smart door lock will certainly be the next norm of creating a smart home. So be a pioneer user of this technology in our country and set an example to other smart home enthusiasts.
