Why Change Your Locks?

Your door locks are the first line of defense for your Thornton home. Over time, locks wear down, technology improves, and circumstances change. The warm Southern California sun and occasional Santa Ana winds can warp door frames and affect lock alignment over time, which can degrade lock components faster than expected. A professional lock change ensures your home is protected with modern, reliable hardware.

Types of Residential Locks We Install

• Knob and lever handle locks — for interior doors and bedrooms
• Keypad locks — enter a code instead of carrying a key
• Single-cylinder deadbolts — the most common residential door lock
• Smart locks with keyless entry — WiFi and Bluetooth-enabled locks
• Double-cylinder deadbolts — keyed on both sides for added security
• High-security locks — pick-resistant and bump-proof models from Medeco and Mul-T-Lock
