Lock Replacement and Smart Lock Upgrade Checklist for San Carlos Homeowners

Use this checklist before you replace or upgrade locks

Replacing locks or upgrading to smart locks improves security and convenience—but only if you plan correctly. This checklist helps homeowners in San Carlos, CA evaluate needs, choose hardware, and verify installation. San Carlos Lock and Key serves Redwood City, Belmont, Menlo Park and San Mateo and is available 24/7 at (650) 489-4463.

Pre-replacement checklist

  • Identify vulnerable entry points: Prioritize front and back doors, garage doors, and ground-level windows.
  • Confirm door conditions: Ensure doors and jambs are solid and square. Weak frames need reinforcement for effective deadbolts.
  • Inventory current hardware: Note brands, grade, and whether locks are mortise, cylindrical, or integrated with multipoint systems.
  • Decide on goals: Are you replacing for security after a break-in, for lost keys, or to add smart features like guest access and remote control?
  • Check compatibility: If considering a smart lock, confirm it fits your door thickness and existing deadbolt footprint.

Choosing deadbolts and installation tips

When selecting a deadbolt, focus on quality and proper installation:

  • Choose a high-grade deadbolt: Look for sturdy construction and at least a 1-inch throw for the bolt.
  • Reinforce the strike plate: Use long screws into the wall framing, not just the door trim, to resist kick-ins.
  • Consider single vs double cylinder: Single-cylinder deadbolts use a key outside and thumb turn inside; double-cylinder use keys both sides—evaluate safety and egress concerns.
  • Professional alignment: Proper hole placement and bolt alignment prevent binding and improve longevity.

Smart lock upgrade checklist

  1. Decide connectivity: Bluetooth, Wi‑Fi, or smart home protocols (Z-Wave, Zigbee). Choose based on range, integrations, and reliability.
  2. Keep a keyed backup: Ensure a physical key option exists in case of battery or network issues.
  3. Power and alerts: Confirm battery life monitoring, low-battery alerts, and reliable power management.
  4. Security features: Look for encryption, two-factor access options, and the ability to manage guest codes and schedules.
  5. Privacy and account control: Know how account access is managed, who can add/remove users, and how data is stored.

Post-install checklist — what to test

  • Manual operation: Test keys, thumb turns, and the physical deadbolt throw for smooth engagement.
  • Electronic functions: Verify app control, code entry, remote lock/unlock, and any automations.
  • Backup access: Confirm physical keys and emergency override work as intended.
  • Share access securely: Set unique user codes for family, guests, and contractors and remove codes when no longer needed.
  • Document and label: Record new keyways, serial numbers, and change log for future reference.
