Types of Home Locks

When it comes to securing your home in Wilkes Barre Pennsylvania choosing the right lock is crucial. At Lomo Locksmith, we understand the importance of protecting your family and belongings. That's why we offer a comprehensive range of home locks tailored to meet your security needs.
Deadbolt Locks are among the most popular choices for exterior doors. Known for their strength and durability, deadbolts provide a high level of security by requiring a key to open from the outside. Whether you opt for a single or double-cylinder deadbolt, these locks are a solid choice for enhancing your home's security.
Smart Locks are becoming increasingly popular for homeowners who value convenience and modern technology. These locks offer keyless entry, remote access, and integration with home automation systems. With features like fingerprint recognition and mobile app control, smart locks provide a blend of security and ease of use.
Mortise Locks offer a classic, time-tested design that combines aesthetics with security. These locks are often found on older homes but are still favored for their robust construction and resistance to tampering.
Knob and Lever Locks are commonly used for interior doors, providing a balance between functionality and security. While they may not be as secure as deadbolts, they are ideal for rooms where high security is not the primary concern.
At Lomo Locksmith, we are committed to helping you choose the right lock for every door in your home. Contact us today for expert advice and professional installation services across Wilkes Barre Pennsylvania .

Should I Rekey or Replace My Locks?

Deciding between rekeying or replacing your locks can be a tough call for homeowners in Wilkes Barre Pennsylvania . At Lomo Locksmith, we understand the importance of making the right choice for your security needs. Both rekeying and replacing locks offer distinct benefits, but knowing which option is best for your situation is key to keeping your home safe.
Rekeying Your Locks
Rekeying involves changing the internal pins of your existing locks, making old keys useless while allowing you to use a new key. This option is ideal if you’ve recently moved into a new home, lost your keys, or want to prevent unauthorized access without altering your door hardware. Rekeying is cost-effective and quick, offering an immediate solution to security concerns.
Replacing Your Locks
Replacing your locks involves installing new hardware altogether, which is the best choice if your current locks are old, damaged, or you want to upgrade to a more secure option like deadbolts or smart locks. It’s also recommended if your locks have been tampered with or compromised. Replacing locks provides an opportunity to enhance your home’s overall security with modern features.
Which Option Is Right for You?
If your locks are in good condition and you’re simply concerned about key control, rekeying is a great, affordable choice. However, if you’re looking to upgrade or if the locks are damaged, replacing them is the way to go.
Lomo Locksmith offers expert rekeying and lock replacement services across Wilkes Barre Pennsylvania . Contact us today for a professional assessment and to enhance your home security!
