I chose to consider a conversion kit for several reasons. First, it allows me to upgrade my existing door hardware without replacing the entire door. Second, these kits are often compatible with various brands and styles, making them a versatile choice. Lastly, I appreciated the cost-effectiveness, as it was more affordable than a full lock replacement.
Key Features to Look For

- Design Options: Since aesthetics were important to me, I considered kits that offered a variety of finishes to match my door’s style.
Budget Considerations
Setting a budget was vital in my purchasing decision. Mortise lock conversion kits can vary significantly in price. I found that while some kits are budget-friendly, investing a little more can provide better quality and security features. I aimed for a balance between cost and quality to ensure I made a worthwhile investment.
Where to Buy
I explored several places to buy my mortise lock conversion kit. Local hardware stores provided the benefit of seeing the product in person and getting expert advice.
