House rekey cost in San Marcos, CA.
Last reviewed July 2026 · Swift Key San Diego
Rekeying changes which key opens your locks without replacing the hardware, so it is the cheapest way to lock out anyone who still holds an old key. Price comes down to how many cylinders you have and the grade of hardware on the doors.
Why rekey runs $100 to $185 for a typical inland home in San Marcos
Escondido, Poway, and San Marcos master-planned homes often run 3 to 5 exterior locks plus pool and side gates, so cylinder count pushes the total up. Rancho Santa Fe and Fairbanks Ranch estates with restricted keyways price above the band.

What moves the rekey price
- Cylinder count. Most homes run 3 to 5 exterior cylinders (front, back, garage entry, side gate). More doors, higher total.
- Hardware grade. Standard Kwikset and Schlage rekey fast. Restricted keyways (Medeco, Mul-T-Lock) cost more per cylinder.
- Service call. A mobile service call is bundled into most quotes and usually waived at three or more cylinders.
- Time of day. After-hours and same-day priority rekeys carry a surcharge over scheduled daytime work.
Rekeying is far cheaper than replacing locks: you keep the existing deadbolts and knobs and pay only to re-pin them to a new key.
