Smart Locks for a Keyless Home

The Case for Going Keyless

Physical keys have served us well for centuries, but they have real limitations: they can be lost, copied without authorisation, and they offer no record of who came and went. Smart locks address all of these shortcomings while adding genuine convenience to daily life.

This guide covers everything you need to know before choosing a smart lock for your home.

What Is a Smart Lock?

A smart lock is an electronic door lock that can be operated without a physical key. Instead, access is granted via a smartphone app, keypad, key fob, fingerprint reader, or a combination of these. Most smart locks also retain a mechanical key override as a backup.

Beyond simple locking and unlocking, smart locks typically offer:

• Remote operation - lock or unlock your door from anywhere in the world via an app
• Access logs - a timestamped record of every entry and exit
• Temporary access - issue a time-limited code to a tradesperson, guest, or cleaner without cutting a new key
• Automation - link with other smart home devices to trigger actions when the door is locked or unlocked
• Notifications - receive an alert if the door is left unlocked or if an access attempt fails

Types of Smart Locks

Bluetooth Smart Locks

These connect to your smartphone via Bluetooth, typically operating within a range of around 10 metres. They are simple to set up, do not require a home network, and tend to have excellent battery life. The trade-off is that you cannot operate them remotely when you are away from home.

Wi-Fi Smart Locks

Wi-Fi locks connect to your home router, giving you full remote access from anywhere with an internet connection. Some models require a separate hub or bridge device. They are the most flexible option but tend to consume more battery power.

Z-Wave Smart Locks

Z-Wave is a low-energy wireless protocol designed specifically for home automation. These locks require a compatible Z-Wave hub to operate but integrate seamlessly with broader smart home ecosystems and offer good battery life.

Biometric Smart Locks

These use a fingerprint scanner (and sometimes facial recognition) as the primary authentication method. They offer high security and genuine convenience - no phone, key, or code needed - but command a higher price and require occasional re-enrolment as the scanner calibrates over time.

Advantages of Smart Locks

• No key to lose - eliminates the most common reason for calling an emergency locksmith
• Granular access control - grant different access levels to family members, regular visitors, and one-time guests
• Peace of mind - check the lock status and view entry history remotely
• Integration - connect with video doorbells, alarms, and smart lighting
• Keyless entry is faster - hands-free unlocking as you approach the door is particularly useful when carrying shopping

Disadvantages to Consider

• Higher upfront cost than traditional locks
• Battery dependence - most smart locks run on AA batteries; a flat battery at the wrong moment can be inconvenient, though most models warn when the battery is low
• Compatibility - not all smart locks fit every door type; check the lock and door measurements carefully before purchasing
• Technology risks - any connected device can potentially be vulnerable to cyber attacks; choose reputable brands with regular firmware updates and strong encryption
• Network reliance - Wi-Fi locks lose remote functionality during an internet outage

Installation and Maintenance

Fitting a Smart Lock

Most retrofit smart locks are designed for DIY installation and include detailed instructions. The process typically involves:

1. Removing your existing deadbolt hardware
2. Fitting the new lock body and mounting plate
3. Pairing the lock with the manufacturer’s smartphone app
4. Testing all entry methods before considering the installation complete

If you are not confident in DIY fitting, or if your door requires modifications, a professional installation ensures the lock operates correctly and the door remains secure. City Locksmith London can handle smart lock installation alongside any lock change or upgrade.

Keeping Your Smart Lock Performing

• Check and replace batteries before the low-battery warning activates
• Keep the app and firmware updated to receive security patches
• Clean the keypad or fingerprint reader periodically
• Test all entry methods every few months to catch any issues early

Should You Upgrade to a Smart Lock?

If you value convenience, frequently need to grant temporary access to others, or want a detailed record of entries to your home, a smart lock is worth the investment. For most homes, a Wi-Fi-enabled lock with a keypad backup offers the best combination of flexibility and reliability.
