This is possible depending on the existing type of lock you have on your door.

In general, our igloohome Deadbolt can replace your existing lock or it can be added on if you have a mortise lock. 

Please see article attached for a detailed before and after installation photos as well as compatibility guide.

For further help, you may send us photos of your existing lock (front, back and side) as well as the measurement of the thickness of your door in mm for us to assist you further.
