Island Lock King - Lock Replacement Service

 Upgrading your home or business security? Island Lock King offers fast, reliable lock replacement services across Nassau and Suffolk County. Whether your lock is outdated, broken, or you’ve recently moved, we’ll replace it with high-security hardware designed to protect what matters most.

We carry and install:

• Deadbolts and smart locks
   
• High-security commercial locks
   
• Keyless entry systems
   

Serving towns like West Babylon, Deer Park, Huntington, and Brentwood, we bring the latest locking technology straight to your door — and install it same-day.

 Don’t replace the entire lock — rekey it instead! Rekeying is a fast, cost-effective solution for changing key access without changing the entire lock system. It’s ideal after:

• Moving into a new home
   
• Tenant turnover
   
• Lost or stolen keys
   

Our mobile locksmiths service homes and businesses in Babylon, Copiague, Lindenhurst, and Bethpage. We rekey all major lock brands and ensure only your new key works — restoring full peace of mind.

 Broken lock? Jammed deadbolt? Don’t risk getting locked out or compromising your security. Island Lock King specializes in lock repairs for both homes and commercial properties across Long Island.

• Loose or spinning cylinders
   
• Key won’t turn in lock
   
• Smart lock malfunctions
   
• Deadbolts not engaging
