Exterior Door Locks FAQ
What is the difference between ANSI Grade 1 and Grade 2 exterior door locks?
ANSI Grade 1 exterior door locks are the highest commercial-grade security standard, tested to withstand 6-8 million cycles and resist forced entry attempts. Grade 2 locks are residential-grade with 400,000 cycle testing, suitable for most homes but with slightly less durability.
How often should I replace my exterior door locks?
We recommend replacing exterior door locks every 7-10 years, or immediately after moving into a new home. If you notice signs of wear, difficulty turning the key, or visible damage, replacement should occur sooner.
Can smart exterior door locks be hacked?
High-quality smart exterior door locks use advanced encryption (AES-256) and two-factor authentication to prevent hacking. While no system is 100% unhackable, premium models offer security comparable to traditional locks with added convenience benefits.

Exterior Door Locks FAQ Continued
Are bump-proof exterior door locks really effective?
Our bump-proof exterior door locks feature specially designed pins and advanced cylinder technology that makes traditional bumping techniques ineffective. These locks have been independently verified by security testing laboratories to resist all known bumping methods.
What's the best exterior door lock for extreme weather conditions?
For areas with extreme weather, we recommend our Marine-Grade series with 316 stainless steel construction, sealed internal mechanisms, and special corrosion-resistant coatings. These exterior door locks withstand salt air, heavy rain, and temperature extremes from -60°F to 300°F.
Can I rekey my exterior door locks myself?
Many of our exterior door locks come with user-rekeying systems that allow homeowners to change keys without professional assistance. However, for maximum security, we recommend professional rekeying when moving into a new property or after security concerns.
