Smart locks offer keyless entry, mobile access, and flexible control, making them popular in Westside apartment buildings. While convenient, these systems rely on battery power. When batteries drain without warning, tenants can lose access, and property managers may face urgent service calls.
Understanding how smart locks use power and how to maintain them helps prevent unexpected lockout interventions. Whether you’re a resident or manage multiple units, proper planning and regular maintenance keep these devices running reliably.
How Smart Locks Use Battery Power
Most smart locks operate using AA or CR123 batteries. These models function without hardwiring, which is ideal for older apartments. Power supports functions like auto-locking, app syncing, and keypad lighting.
Battery life varies based on usage frequency, lock model, and wireless features. Locks connected via Wi-Fi typically draw more power than those using Bluetooth or Z-Wave. Models with touchscreens or fingerprint access may also drain faster.
Mobile apps often alert users when batteries run low. Ignoring these alerts can result in complete failure, especially in high-traffic units. Some locks also signal low battery through lights or sounds, so pay attention to these early warnings.
Signs Your Lock Needs a Battery Change
Battery issues typically exhibit symptoms before complete failure. Recognizing these signs early helps prevent being locked out.
- Delays between code entry and unlocking
- Missed or delayed responses from smartphone apps
- Dim keypad lighting or flickering indicators
- Weak motor sounds when engaging the deadbolt
- In-app low battery warnings
If any of these occur, replace the batteries immediately, even if the lock still operates. Waiting too long may result in full lock failure.
Extend Battery Life and Add Backup Access
Avoiding failure starts with a few consistent maintenance habits. Choose high-quality, non-rechargeable alkaline batteries, and replace all batteries at once to ensure even performance. Avoid mixing battery brands or combining old and new cells. Also, check for signs of corrosion in the battery compartment.
To improve reliability, also look for smart locks that offer backup access options. These prevent full lockouts in the event of a battery failure.
Recommended smart lock features and practices:
- Use locks with hidden key slots or physical override keys
- Choose models with 9V emergency power ports
- Enable guest code options for temporary access
- Limit auto-locking and reduce Wi-Fi use in low-traffic areas
- Keep firmware updated for better battery optimization
Models with app-managed access codes or fingerprint scanners should be tested regularly to ensure all features continue working as expected.
Managing Battery Maintenance in Multi-Unit Properties
For landlords or building managers, setting a schedule for battery checks prevents problems across multiple apartments. Track battery replacement dates, monitor mobile alerts, and inspect units at regular intervals.
Rather than relying solely on tenants to report issues, establish a proactive plan. For example, check locks every quarter and inspect strike plate alignment annually. Review usage logs via the management app if your system offers it.
If you manage furnished units or short-term rentals, swap batteries between guest stays. Keeping spare batteries onsite also helps reduce delays when replacements are needed.
Prevent Lockouts With Smart Planning
Lockouts due to battery failure can disrupt routines, delay appointments, or require emergency locksmith service. A few preventive measures can make a big difference. Encourage residents to respond promptly to battery alerts. Install key lockboxes with a physical backup or provide management with master access codes.
For units with high usage, such as those with cleaning staff, dog walkers, or frequent deliveries, select locks with robust battery performance and clear alerts.
