Locksmith Service Cost | Lock Change Downey
This Lock Change Cost page is designed to give you a clear idea of what to expect when pricing lock change and rekey services in Downey, California. Lock Change Downey believes in transparent estimates and explaining how lock type, door condition, and labor affect the final cost. All prices listed here are general estimates meant to help you plan.
Lock prices vary widely depending on the brand, security level, and style you choose. Basic residential deadbolts cost less than high-security or smart locks, while commercial and mortise locks usually require more labor and specialized parts. Labor costs depend on installation complexity, door alignment, and whether any repair or modification is needed.
Rekey services are typically more affordable because the existing hardware stays in place and only the internal pins are changed. Lock replacement costs more because it includes new hardware and installation. Your technician will inspect the door and lock on-site and provide a final price for approval before any work begins.

What Affects Lock Change Costs
The biggest factor is the type of lock being installed. A basic residential deadbolt requires less time and fewer adjustments than a mortise or storefront lock. High-security locks cost more due to restricted keyways and hardened components.
Door condition also plays an important role. Warped doors, worn strike plates, or misaligned frames can increase labor time. In some cases, minor repairs are needed to ensure the new lock operates smoothly and securely.
Labor pricing includes proper installation, testing, and adjustments so the door locks and unlocks correctly. Professional installation helps prevent future issues like sticking keys, loose hardware, or premature wear. This saves money over time by avoiding repeat service calls.
