Deadbolts add strong protection to exterior doors. Unlike spring bolt locks, deadbolts do not retract automatically and cannot be opened without the correct key or code. Choosing the right type of deadbolt helps reduce break-in risks and adds security to your home.
Why Deadbolts Matter
Deadbolts increase door resistance against forced entry. Most burglars attempt to enter through a front or back door, and a weak lock gives them an easy path. A properly installed deadbolt delays access and discourages continued attempts.
In Los Angeles neighborhoods like Eagle Rock or Sherman Oaks, homes with visible deadbolts are less likely to be targeted. Deadbolts work best when installed on solid-core or metal doors with reinforced frames.
Types of Deadbolts
Different door setups call for different lock styles. Understanding the options helps you match the deadbolt to your security needs.
1. Single-Cylinder Deadbolts
These deadbolts use a key on the outside and a thumb-turn on the inside.
Best for:
- Front and back doors without glass
- Homes with few residents
Benefits:
- Easy to lock and unlock from inside
- Quick exit during emergencies
Limitations:
- If there is glass near the lock, intruders can break it and turn the thumb latch
2. Double-Cylinder Deadbolts
These require a key on both sides of the door.
Best for:
- Doors with nearby windows or glass panels
Benefits:
- Prevents someone from unlocking the door by reaching inside
Limitations:
- Slower to exit during emergencies unless a key is nearby
Local building codes in parts of California may limit use of double cylinder locks on doors used for emergency exits.
3. Keyless and Smart Deadbolts
These locks use a keypad or mobile device instead of a traditional key.
Best for:
- Residents who want to manage access remotely
- Households with frequent guests or service workers
Benefits:
- Can track who enters and when
- No need to carry or hide spare keys
Limitations:
- Needs batteries or a power source
- May require Wi-Fi or Bluetooth connection
Keyless deadbolts are common in short-term rental properties and updated homes throughout Pasadena and Burbank.
Factors to Consider When Choosing a Deadbolt
Not every deadbolt fits every door or situation. Before you buy, review the following points:
- Door Material: Solid wood or metal supports deadbolts better than hollow doors
- Glass Near Entry: Use double cylinder locks if glass is close to the thumb-turn
- Ease of Use: Seniors or children may need a deadbolt that operates without a key
- Access Management: Choose a smart lock if you share your home with renters or guests
- Emergency Exit: Single cylinder locks allow faster exit during fire or power outages
To improve deadbolt performance, consider also adding a reinforced strike plate and longer screws. These parts keep the bolt secure during forced entry.
Common Mistakes to Avoid
Deadbolts must be installed and used properly to provide full security. Avoid these common errors:
- Using a deadbolt on a hollow-core door
- Installing without reinforcing the door frame
- Choosing a keyless lock without battery backup
- Leaving a key in the interior cylinder of a double deadbolt
- Failing to change codes on a smart lock after guests leave
Security depends on the full door setup—not just the deadbolt. A strong lock on a weak door will still fail under force.
Real Examples in Los Angeles Homes
In Glendale, many older homes use double cylinder deadbolts on rear doors with large window panes. This reduces the risk of forced entry through glass.
In Venice Beach, residents use smart deadbolts to manage access for dog walkers and house cleaners. These locks allow temporary codes and real-time tracking.
In new construction near Highland Park, contractors often install single-cylinder deadbolts with reinforced metal plates for front and garage side doors.
Lock In Better Home Security Today
Choosing the right deadbolt is a simple step that adds meaningful protection to your home. Whether you prefer using a key, entering a code, or unlocking your door through a remote device, the correct deadbolt improves both access control and physical security. Your choice should match your door’s material and layout. Solid doors support deadbolts more effectively, and certain setups—such as doors with nearby glass—may require double cylinder locks to prevent tampering.
Reinforcing the strike plate and using longer screws adds strength where it matters most. Always keep a key near the exit if your lock requires one on both sides. If you use a smart deadbolt, remember to update your access codes after guests leave or after a move. If you’re not sure which deadbolt is right for your home, a professional locksmith can help.
