"Walter and Glen at Protect Your Home Group with ADT are the best people to talk to in terms of security alarm. Being a locksmith myself I know how important it is to deal with the right people. I referred a lot of customers to them and so far they are happy with their service. I myself got one for my house. Thank you for a consistent service and great deal."

Locksmiths FAQs, answered by experts

Security experts recommend deadbolt locks as the most secure option for a house's exterior or entry doors. Deadbolts provide the best security because they can prevent most types of forced entry and are harder to lockpick. Common types include the standard single-cylinder deadbolt, which is often found on front doors. For enhanced security, you can opt for a double-cylinder deadbolt, which requires a key to operate from both the inside and the outside.

If you’re having an issue turning the key inside a lock, chances are there is dust or dirt buildup within the cylinder. The easiest solution is applying a dry lubricant to the lock, which loosens the dirt buildup. You may need to turn the key a few times for it to work properly again.

Smart deadbolts are a worthwhile investment for homeowners seeking more convenience, flexibility, and advanced features than a traditional deadbolt can provide. While a strong conventional deadbolt offers sufficient security for most, smart deadbolts provide significant upgrades.

Key benefits include keyless entry via smartphone, keypads, or biometric sensors, and the ability to lock or unlock your door remotely. You can also manage access for guests by creating temporary codes, eliminating the need for physical keys and the risk of them being lost or duplicated. Many models integrate with smart home systems and offer features like automatic locking, entry-exit monitoring, and tamper alerts with encryption for enhanced security.

However, there are downsides to consider. Smart deadbolts are more expensive than their traditional counterparts and rely on batteries and wireless networks to function. This dependency introduces potential vulnerabilities, such as hacking by skilled intruders and privacy concerns. Installation can also be more complex. Despite these drawbacks, the added layer of convenience and protection makes them a compelling option for many.

It depends on the quality of the keyless lock and usage, but in general, you can expect a keyless lock to last around three to five years. The batteries typically last around six to 12 months. The good news is most keyless locks include a low battery indicator so you can receive ample warning if your battery is about to die.

You might want to change a door lock entry code for a handful of reasons. The most common answers are extra security or a forgotten code. You may also find yourself in a position where you need to temporarily change the code to allow a guest to come and go freely but want to switch it back once things return to normal.
