Smart locks let you lock and unlock your door from your phone, share access with guests and get notifications when someone comes home. For renters, though, replacing a lock may conflict with your lease. Fortunately, there are smart lock options designed to work with your existing hardware.
This guide explains smart lock options for renters, how to approach your landlord and what to consider for security. It is general information, not legal advice. Your lease and local laws determine what you are allowed to do.
Check Your Lease First
Many leases include rules about changing or adding locks. Some require landlord permission, and some require you to provide a key to the landlord. Laws also vary by location regarding landlord access and lock changes.
Before installing any lock:
- Read your lease for clauses about locks, alterations and keys.
- Ask your landlord in writing and keep a record of their response.
- Clarify expectations, such as whether you must provide access codes or keys and restore the original lock when you move.
Types of Smart Locks
Retrofit Smart Locks
Retrofit locks attach to the interior side of an existing deadbolt. The exterior keyhole and key stay the same. Examples include models from August and some SwitchBot and Level products.
Why renters like them:
- The original key still works.
- No exterior changes.
- Often easier to install and remove.
Full Replacement Smart Locks
These replace the entire deadbolt, including the exterior. Brands include Schlage, Yale, Kwikset, Lockly and others. They often include keypads or fingerprint readers.
For renters: These require removing the original lock, so landlord permission is usually essential. Keep the original lock to reinstall when you move.
Smart Lock Add-Ons and Keypads
Some retrofit systems offer separate keypads that mount outside, often with adhesive. Ask about adhesive use on exterior doors.
Over-the-Thumbturn Devices
Some products fit over the interior thumbturn without removing any parts. Compatibility and security vary.
Compatibility Checks
- Deadbolt type: Most retrofit locks are designed for single-cylinder deadbolts.
- Door alignment: A deadbolt that sticks or needs pushing on the door may cause a motorized lock to jam.
- Door thickness and backset: Important for replacement locks.
- Space around the thumbturn: Retrofit locks need clearance.
Manufacturers often provide compatibility checkers.
Connectivity
- Bluetooth: Works when you are nearby. Remote access often needs a bridge or hub.
- Wi-Fi: Allows remote access but may use more battery.
- Thread and Matter: Newer locks may support Matter over Thread, which can work across ecosystems. See Matter explained.
- Z-Wave and Zigbee: Need compatible hubs. See smart home hubs explained.
Features to Consider
- Auto-lock after a set time
- Auto-unlock when you arrive
- Guest access with schedules
- Activity logs
- Door sensors to confirm whether the door is closed
- Voice control with Alexa, Google Assistant or Siri, often with PIN requirements for unlocking
- Battery alerts
Security Considerations
- Physical security: A smart lock is only as strong as the door, frame and strike plate. Retrofit locks rely on the existing deadbolt.
- Account security: Use a strong, unique password and two-factor authentication. See how to secure your smart home.
- Firmware updates: Keep the lock and app updated.
- Voice unlocking: Require a PIN if you allow it.
- Physical key backup: Keep a physical key accessible in case batteries die.
Look for locks certified to industry standards such as ANSI/BHMA grades for replacement locks.
Installation Tips for Renters
- Photograph the original setup before you start.
- Keep all original parts in a labeled bag.
- Follow the manufacturer’s instructions carefully.
- Avoid drilling unless your landlord approves.
- Test the lock many times before relying on it.
See our smart lock installation guide for detailed steps.
Moving Out
- Remove the smart lock and reinstall the original hardware.
- Delete the lock from your account and remove all user codes.
- Factory reset the lock before taking it to a new home.
- Return all original keys to the landlord.
Shared Housing and Roommates
In shared homes, agree on who manages the lock, how codes are shared and what happens when someone moves out. Change or delete codes for former roommates promptly.
Battery Planning
Most smart locks run on batteries, and battery life depends on use, connectivity and temperature. Keep spare batteries at home and replace them when the app warns you, rather than waiting for the lock to stop working. Some locks include emergency power contacts on the exterior so you can temporarily power the lock with a battery if needed; check whether yours does.
Questions to Ask Before Buying
- Does your lease allow the change, and has your landlord agreed in writing?
- Is your deadbolt compatible with retrofit models?
- Do you want remote access, and will you need a bridge or hub?
- Which smart home platform will you use to control it?
- How will you get in if the batteries die?
Talking to Your Landlord
A short, clear request often makes approval easier. Explain which lock you want to install, whether it replaces only the interior thumbturn or the entire deadbolt, and confirm that you will keep the original hardware and restore it when you move out. Offer to share a working key or code if your lease requires landlord access. Get approval in writing, even by email, so there is a record.
Rekeying and Key Access
Many smart deadbolts include a physical key cylinder, and some can be rekeyed by the owner. In a rental, changing the keyed cylinder may conflict with your lease, so check first. Retrofit locks avoid this issue because they keep the existing exterior cylinder and keys.
Battery Planning
Smart locks typically warn you in the app when batteries run low. Keep spare batteries on hand, and learn your lock’s emergency options before you need them. Some keypad locks can be powered temporarily through an external contact or USB port, while others rely on a physical key backup. Knowing this ahead of time prevents being locked out.
Before You Move Out
Remove the lock from your account, factory reset it, reinstall the original hardware and test that the old keys work. Patch any small screw holes if needed.
