With the increase in smart devices on the market, most people agree that one of the key features in a smart home is the smart lock. A smart lock is a device that allows entry into your home without a key. Some use a keypad with a code, fingerprint scanner, or smartphone App. They offer additional security, without the disadvantages of traditional mechanical locks, and come in many types to accommodate your particular needs and home system.

The variety of locks on the market also means there is a wide range of associated costs. The national average cost is between $150 and $400 for an installed smart lock and related accessories, with most homeowners paying $200 for a wifi-enabled smart lock with one accessory. Some simple models that fit over an existing lock are $100, and high-end locks that tie into a sophisticated security system with biometric features are around $1,200.

There are many different types of smart locks on the market. Each type functions differently, and some may require specific connections or accessories to work properly. Each one gives you the convenience and security you want but with varying features:

Keypad Cost

Choices in this category include a key lock with a backup keypad or a keypad integrated into your cell phone for remote entry. There are also affordable units that just have a keypad and no wifi capabilities. You can purchase a reputable unit for $100-$250.

RFID Lock System Price

A smart lock equipped with an RFID opens using a chip attached to a programmable card or a coin-sized RFID card. Locks with RFID capabilities often come with wifi, keypad, and key entry. The average price is $100-$300.

Wifi Door Lock

With the ability to connect to your wifi, these door locks enable you to remotely change access codes or check if someone has entered your home. This type of lock is also compatible with systems like Alexa or Siri. Average costs for the lock with a gateway that plugs into the wall are $200-$300.

Bluetooth Door Lock

With many of the same features as wifi locks, Bluetooth door locks enable you to set codes and unlock doors remotely, as well as set auto locks and unlocks. These units cost around $200-$300 for a basic unit.

Biometric Door Lock Price

Using a touchscreen, these smart locks recognize your fingerprint to gain access. There are often backup methods, including keypad, RFID, and smartphone access. The cost for these units is $250-$450.

Z-Wave Door Lock

Z-Wave technology allows for an ultimate smart home setup, including smart locks. It uses radiofrequency to integrate with your main control system. The unit itself is affordable and programmable via your smartphone. To take advantage of the more advanced features, such as automatic door locking and enhanced security, a hub and Alexa device are often needed. The average cost for a unit with Z-wave capability is $250-$400.

Smart Lock Costs by Brand

The brand you choose also impacts the functionality. Not every brand works with all systems, so if you want wifi, Z-Wave, or another connectivity-style system, you may be limited in what brands to choose from. Likewise, not all brands are compatible with all systems, with some working with Apple Home but not Alexa and others that prefer Google. A few brands work with all. Some brands of note include:

Smart Lock Installation Cost

Smart locks are very easy to install, and many are designed for homeowner installation, meaning you do not need a professional. However, if you feel more comfortable having someone else do the job, a handyman can install most smart locks. You finish the setup to personalize the lock and connect it to the system yourself. Installation of a smart lock is fairly simple and usually takes less than 30 minutes. Some locks work with your existing deadbolt, only swapping out the visible escutcheons on the door and not the internal mechanism. Other locks require a complete swap out.

Amazon also offers installation of smart locks in its Home Services category. They cover installation, programming set up, creating virtual keys, door modifications, and more. Setting up a Smart Hub is not included. Home Services installation is available in select areas. To purchase your device, type in your location to receive availability and a quote. The average cost per door is between $150 and $400.

In most cases, the strike plate and deadbolt are unscrewed, and the outer escutcheons are removed. All pieces of the old lock are taken out. The new internal parts of the smart lock are mounted and screwed into place. Then, the new escutcheons are screwed over them. The set up of apps, Bluetooth, wifi, hub, or keypad pins takes only a few minutes more. Some homeowners feel comfortable doing this installation, especially for locks designed for easy installation.

The average cost to install a smart lock is around $50. When added to the price of the lock and hub, this makes the total project cost around $200.

Types of Doors to Secure

Smart Locks can be installed on any door. Front doors are the most common, but office doors, basement doors, and garage doors are also popular. Wherever you want to restrict visitors or access is a great place for additional security. Home, office, and storage lockers can all benefit from smart locks:

Pros and Cons of Smart Locks

The biggest advantage of installing a smart lock in your home is convenience. Depending on the lock, they have many features that make securing and entering your home simpler, such as:

  • Unlocking the doors when away to let someone in
  • Keeping a record of who accessed the door
  • Never needing a key
  • Being able to unlock the door with your hands full
  • Tying the door into other smart systems so that the lights turn on when you open the door or the heater kicks on

However, there are some drawbacks to the various locks as well. If the power or wifi goes out, the locks may malfunction. Wet or icy weather may make a biometric lock malfunction. Batteries wear out, and when that happens, the lock ceases to function without a key. Some systems need expensive additional components, such as hubs, to work properly. Any wifi-enabled system is hackable, and therefore a security threat.

Many people find that the disadvantages are overcomeable or manageable and that the convenience outweighs any potential concerns. Others feel more secure with locks that have backup keys.

Are Smart Locks Safe?

Smart Locks are a great option, but there are risks involved with any lock, both mechanical and smart. If someone sees you type in your code, they can access your home. Covering the pad from view while typing and changing the code periodically alleviates this threat. Smart locks that use your cellphone can be hacked, so be sure to use passwords and security features. Fingerprint identification is very secure, but it is important to have a backup option if there is a glitch, and your fingerprint is not recognized.

Enhancement and Improvement Costs

Smartphone Compatibility

Some wifi and Bluetooth smart locks offer an app as part of the system, which allows you to control the lock from your phone. This may unlock the door when your phone is near or give you remote access. For locks with this system, there is no additional cost.

Remote Control

Some lock systems use a fob or remote control that lets you lock the door from a distance. This is often an added accessory and can increase the cost by $25 to $50.

One-touch Lock

One-touch or touch technology locks use a radio-frequency identification (RFID) system, but instead of needing a fob or card in your hand, you can simply have it nearby and touch the lock to open the door. One-touch locks typically cost the same as any RFID lock system, $100 to $300.

Additional Considerations and Costs

  • If you live in a rental, always get permission to install a smart lock before proceeding. Many landlords require a copy of the key and access in case of an emergency. If you want to take the lock with you when you move out, make arrangements beforehand.
  • There are locks, such as the August, that can be fitted over the current lock. If your landlord permits you, get the agreement in writing and choose a lock that fits in the door with no modifications to the frame or deadbolt. Look for locks that say smart lock conversion kit or retrofit smart lock.
  • Always have a backup plan for getting into the home in case of a malfunction, power outage, or wifi outage. This may mean using an alternate door or having a backup key with you at all times.
  • When installing a smart deadbolt, you may need to realign the door first if you live in an older home. Older homes frequently require you to push on the door as you lock it. This will not work with a smart deadbolt.
  • Always make sure the new lock fits with your door, including any decorative trim or other potential obstructions.
  • Smart locks run on batteries, which operate the wifi capability, LED lights, and the mechanism that operates the door. Batteries wear out over time and need to be replaced.


  • How much does it cost to change a door lock?

Changing a smart door lock can be quite complex. If you choose to have the new door lock professionally installed, the average cost to hire a professional is between $150 and $300 for an installed smart lock and related accessories.

  • What does a smart lock do?

Smart locks offer convenience to the user. They may provide remote entry, sync with home automation systems, or allow you access without a key.

  • Do all smart locks require a hub?

No, some smart locks use biometrics or Bluetooth and do not use a hub. Hubs are used to communicate with wifi and your cell phone.

  • Can smart locks be hacked?​

Yes, wifi, Z-Wave, and other hub-active systems can be hacked. Use security software and change passwords often. Be careful who you give access to.

  • Can Alexa lock my doors?

Yes, Alexa can lock your doors if you have a smart lock that is Alexa-compatible and has voice authorization enabled.​​
