Why Install a Deadbolt?
Deadbolts add an extra layer of security to exterior doors and are one of the most common upgrades homeowners make to improve home protection.
Many older doors either don’t have a deadbolt at all or have hardware that no longer lines up correctly.
Installing a deadbolt is one of the most practical security upgrades you can make to a residential door.
Basic Tools Needed for a Deadbolt Installation
• Tape measure
• Drill
• Hole saw kit
• Screwdriver
• Chisel
• Pencil or marker
• Deadbolt installation template
Most people are surprised by how straightforward the process becomes once the measurements are marked correctly.
Common Deadbolt Installation Mistakes
• Installing the latch upside down
• Drilling the hole too high or too low
• Misaligning the strike plate
• Over-tightening the screws
• Forgetting to check door backset measurements
• Not testing the deadbolt before final tightening
If the bolt binds after installation, use the deadbolt troubleshooting guide to check alignment and resistance before replacing the hardware.
Before buying new hardware for a working cylinder, compare when a lock can be rekeyed instead of replaced.
