Deadbolts

Traditional deadbolts

Mechanical deadbolts

Mechanical deadbolts are the classic choice for home security. They unlock with a key on the exterior and a thumb turn on the interior. Some models include a re-keying option, allowing you to change the key without replacing the lock entirely. Others do not offer re-keying but often come with a lifetime mechanical and finish warranty.

Deadbolts are usually available in single-cylinder (key outside, thumb turn inside) or double-cylinder (key on both sides) configurations. Choosing the right one depends on your home’s layout and your personal security needs.

Re-keying smart keys

In the past, changing a lock meant calling a locksmith or replacing it yourself. Modern smart key systems simplify this process, allowing doors to be re-keyed in seconds using a compatible smart key. This is a practical option for families, renters, or anyone who frequently updates access permissions.

Technology-enhanced deadbolts

Over the past 20 years, advancements in deadbolt technology have transformed home security. Wi-Fi and Bluetooth-enabled deadbolts allow homeowners to monitor door activity, lock or unlock doors remotely, and receive instant notifications via smartphone apps. Even without Wi-Fi, Bluetooth smart locks provide convenient keyless entry.

Some models still include conventional re-keying options. Others provide audible beeps for door status - open or closed - and low battery alerts. Some manufacturers even offer locks that inhibit the transfer of bacteria, adding a layer of hygiene to your entryway.

Deadbolts are sold individually or as part of handle sets, which include an exterior handle and an interior lever or knob.

Smart lock options

Electronic touchscreen smart Locks (Wi-Fi)

These locks use a numeric touchscreen keypad connected to your home Wi-Fi and managed via an app. Unique access codes can be assigned to family and guests, while traditional key access is maintained for peace of mind. Batteries are required.

Electronic fingerprint smart locks (Wi-Fi)

Fingerprint locks allow you to lock or unlock your door with a simple touch. Typically configured as single-cylinder, they connect to Wi-Fi and a smartphone app, storing multiple user fingerprints. Backup keys are included for power outages or technical issues. Coloured LED lights indicate status; usually green for unlocked and orange for locked. Batteries are required.

Electronic keypad smart locks (Bluetooth)

Where Wi-Fi is unavailable, Bluetooth-enabled deadbolts allow keyless entry within Bluetooth range. Users can manage access permissions through a smartphone app while retaining traditional key functionality. Batteries are required.

Security system-enabled deadbolts (Z-Wave/Zigbee)

If your home has a compatible security system, some deadbolts integrate with Z-Wave or Zigbee networks, allowing centralised control through your security hub. Always confirm compatibility with your provider before purchase. Batteries are required.

Electric keypad deadbolts (Non-Wi-Fi/Bluetooth)

These locks are programmed directly at the lock and offer limited user access. Remote operation is not possible, and they do not communicate with smartphones. Many models provide traditional key access and low or backup battery options. Batteries are required.

Choosing the right deadbolt

When selecting a deadbolt, consider:

• Technology vs. simplicity: Do you want a traditional lock or a smart option with remote management?
• Number of users: Fingerprint and keypad locks can accommodate multiple users.
• Connectivity: Wi-Fi, Bluetooth, and security system integration options vary.
• Hygiene: Some models are designed to reduce bacterial transfer.
• Backup options: Always check for traditional key access in case of power or battery failure.
• Warranty: Look for locks with strong mechanical and finish warranties.
