Frequently Asked Questions (FAQs)

This section addresses common questions door lock owners may have regarding maintenance, repairs, and security.

1. How often should I lubricate my door locks?

Answer: It’s recommended to lubricate your door locks monthly to ensure smooth operation and prevent buildup of dirt and debris. In harsher environments, such as areas with high humidity or extreme temperatures, more frequent lubrication may be necessary.

2. Can I use WD-40 on my door locks?

Answer: While WD-40 can be used for temporary lubrication, it is not ideal for long-term maintenance as it can attract dirt and debris. A graphite-based or silicone-based lubricant is preferable for door locks.

3. Why does my key bend when turning the lock?

Answer: A key bending when turning the lock is typically a sign of excessive force being applied, possibly due to a stuck or misaligned lock. Ensure you’re not forcing the key and consider lubricating the lock. If the problem persists, consult a professional.

4. What should I do if my door lock isn’t aligning with the strike plate?

Answer: Misalignment can cause the lock to stick or not function correctly. Check the door hinges and ensure they are secure. You may need to adjust the strike plate or door position. If alignment issues continue, contacting a professional is advisable.

5. How can I prevent my deadbolt from freezing in cold weather?

Answer: Apply a silicone-based lubricant to the deadbolt to create a barrier against moisture. Additionally, consider installing a lock cover to protect it from the elements. In extreme cold, avoid using lock lubricants that can freeze.

6. Is it safe to re-key my lock myself?

Answer: Re-keying a lock can be done DIY if you’re comfortable with the process and have the necessary tools. However, if you’re unsure, it’s safer to hire a professional to ensure the lock remains secure and functions correctly.

7. My smart lock isn’t connecting to my smartphone. What should I do?

Answer: First, ensure your phone’s Bluetooth or Wi-Fi is enabled and functioning. Check that the lock’s firmware is up to date and reboot both the lock and your phone. If connectivity issues persist, refer to the manufacturer’s support or contact a professional via (877) 211-9919.

8. How do I know when it’s time to replace my door lock?

Answer: Consider replacing your door lock if it’s frequently malfunctioning despite repairs, has visible damage, is very old, or if security has been compromised due to lost keys or attempted break-ins. A professional can assess your lock’s condition and recommend replacements when necessary.

9. Can a broken key cause permanent damage to my lock?

Answer: Attempting to remove a broken key improperly can cause further damage to the lock’s internal mechanism. If a key breaks inside the lock, it’s best to contact a professional repairman to safely extract the key without harming the lock.

10. What is the difference between a deadbolt and a regular lock?

Answer: A deadbolt is a highly secure locking mechanism that operates without springs, providing strong resistance against forced entry. Regular locks, such as knob or lever locks, often have spring-based latches that are easier to manipulate but offer less security compared to deadbolts.
