  1. Security Ratings: I researched the security ratings of different kits. A good conversion kit should meet industry standards for security, which gives me peace of mind knowing my home is protected.
  1. Design Options: I also considered the design of the lock. Since it would be a visible part of my door, I wanted something that matched my home’s décor. Thankfully, I found kits that offered various finishes and styles.

Evaluating Brands

With so many brands on the market, I took the time to evaluate a few reputable manufacturers. Here’s what I found helpful:
