Lock change and replacement cost in Coronado, CA.
Last reviewed July 2026 · Swift Key San Diego
A lock change swaps out the physical deadbolt or knob for new hardware, which is the right call when the old lock is worn, damaged, or you want a higher security grade. Cost is driven by the hardware you pick and how many doors you do.
Why lock replacement runs $150 to $360 per door installed in Coronado
Coastal salt air corrodes standard hardware in 5 to 7 years, so marine-grade stainless or solid brass with a PVD finish is the default spec here, which sits at the upper end of the band but roughly doubles service life.

What moves the lock replacement price
- Hardware grade. Grade 3 builder locks are cheapest. ANSI Grade 1 deadbolts and smart-ready hardware cost more but last longer.
- Finish and material. Standard finishes are baseline. Marine-grade stainless or solid brass for coastal air costs more.
- Door prep. A door already bored for a deadbolt installs fast. New bores, old mortise conversions, or repair add labor.
- Door count. Per-door labor drops when several doors are changed and keyed alike in one visit.
If the goal is just controlling who has a key, a rekey is cheaper. Choose a full lock change when the hardware is failing or you want a higher grade.
