Digital Lock Installation: Time Estimates by Lock Type

1. Retrofit Locks (Fastest: 10-20 Minutes)

These attach over your existing deadbolt without removing it.
Pros:

2. Keypad Deadbolts (20-45 Minutes)

Replaces your existing deadbolt with a digital keypad version.
Pros:

• Strong security (ANSI Grade 1)
• Clean, integrated look
  Cons:
• Requires basic tools (screwdriver, tape measure)

3. Full Handle + Keypad Combos (45-90 Minutes)

Replaces both handle and deadbolt for a complete keyless system.
Pros:

• Sleek, modern appearance
• Often includes fingerprint scanning
  Cons:
• May require door adjustments

4. Fingerprint/Biometric Locks (30-60 Minutes)

Adds fingerprint or facial recognition to keypad access.
Pros:

• Fastest entry method
• No codes to remember
  Cons:
• Higher price point

Step-by-Step: What Actually Happens During Installation?

Retrofit Lock Installation (10-20 mins)

1. Remove interior thumbturn (if applicable)
2. Attach mounting bracket over existing deadbolt
3. Secure motor unit with provided screws
4. Install batteries & pair with app

Keypad Deadbolt Replacement (20-45 mins)

1. Remove old deadbolt (unscrew interior/exterior plates)
2. Insert new bolt into door edge
3. Connect exterior keypad & interior thumbturn
4. Test alignment (adjust strike plate if needed)

Watch Out For: Door thickness compatibility—most work on 1-3/8″ to 1-3/4″ doors.

Full Handle Replacement (45-90 mins)

1. Remove entire existing lockset
2. Install new latch & deadbolt
3. Connect wiring (if electronic handle)
4. Calibrate biometric/fingerprint sensors

5 Factors That Affect Installation Time

1. Your Door’s Existing Setup

• Pre-drilled holes = faster install
• Non-standard doors (metal, fiberglass) may need adjustments

2. Lock Type Complexity

• Retrofit models = fastest
• Multi-point locking systems = longest

3. Your DIY Skill Level

• First-timers add 20-30 mins vs. experienced installers

4. Needed Tools

Basic installs require:

• Phillips screwdriver
• Tape measure
• Drill (sometimes)

Missing tools? Add 15+ mins for hardware store runs.

5. Tech Setup

• Wi-Fi/Bluetooth pairing adds 5-15 mins
• Firmware updates can delay first use

When to DIY vs. Hire a Locksmith

DIY Installation Works If:

• You’re replacing same-size hardware
• The lock includes clear instructions
• You have basic tools

Cost Savings:

0vs.100-$300 for professional install

Hire a Locksmith When:

• Your door needs modifications
• You’re installing high-security locks
• You want warranty protection

Pro Tips for Faster Installation

1. Watch the Manufacturer’s Video First (most brands post them on YouTube)
2. Test Fit Before Fully Securing (avoid rework)
3. Use a Magnetic Screw Holder (prevents dropped screws)
4. Check Door Alignment Early (adjust hinges if sticky)

Troubleshooting Common Hangups

Problem: Deadbolt won’t extend fully

• Fix: Adjust strike plate position

Problem: Keypad not powering on

• Fix: Check battery orientation (+/-)

Problem: App won’t connect

• Fix: Reset lock & restart phone

Final Verdict: Budget 30-60 Minutes

Most digital locks install in under an hour—with retrofit models taking less than 20 minutes.

Remember:

• Prep your tools first
• Follow instructions step-by-step
• Test thoroughly before relying on it
