Do Smart Locks Have Alarms?

Smart locks are revolutionizing home security across the U.S., offering keyless entry, remote access, and seamless integration with smart home systems. But beyond convenience, many homeowners wonder: Do smart locks have alarms?

The short answer is yes—many do, but not all. Some smart locks include built-in alarms to deter intruders, while others rely on silent notifications sent to your phone. In this article, we’ll explore:

  • Which smart locks come with alarms?
  • Types of alarms (tamper alerts, forced entry warnings, etc.)
  • How these alarms enhance home security
  • Top smart locks with alarm features
  • Pros and cons of alarm-equipped smart locks

By the end, you’ll know whether an alarm-enabled smart lock is the right choice for your home.

Do Smart Locks Have Built-In Alarms?

Not all smart locks include audible alarms, but many high-end models do. These alarms typically trigger in three scenarios:

  1. Forced Entry Attempts – If someone tries to break in (e.g., prying, kicking, or tampering).
  2. Wrong Passcode Attempts – Too many incorrect entries may set off an alarm.
  3. Unusual Activity – Some locks detect repeated failed unlocks or unusual force.

 

Types of Smart Lock Alarms

Not all alarms work the same way. Here’s a breakdown of the most common types:

1. Tamper Alarms (Forced Entry Detection)

  • Triggers if someone tries to force open the door or pick the lock.
  • Often includes a loud siren (90dB+) to scare off intruders.

2. Wrong Code Alarms

  • Alerts you (or sounds an alarm) after multiple failed access attempts.
  • Helps prevent brute-force attacks (guessing passcodes).

3. Unauthorized Access Alarms

  • Some locks detect if someone tries to remove the battery or disables the lock.

4. Silent Phone Alerts (No Audible Alarm)

  • Instead of a siren, sends a push notification to your phone.
  • Good for renters or people who don’t want loud alarms.

Do You Really Need a Smart Lock with an Alarm?

Pros of Alarm-Enabled Smart Locks

Deters Burglars – A loud siren can scare off intruders before they break in.
Instant Alerts – You’ll know immediately if someone is tampering with your lock.
Extra Security Layer – Works alongside cameras and motion sensors.

Potential Downsides

False Alarms – Some models may trigger accidentally (e.g., kids playing with the lock).
Noise Complaints – A 110dB alarm might annoy neighbors in apartments.
Battery Drain – Frequent alarms may reduce battery life faster.

Final Verdict: Should You Get a Smart Lock with an Alarm?

If security is your top priority, a smart lock with an audible alarm is a great investment. However, if you live in an apartment or prefer silent monitoring, a model with phone alerts may be better.

Key Takeaways

Many smart locks have alarms, but not all—check before buying.
Alarms can be loud (110dB+) or silent (phone notifications).
Consider false alarms and battery life before choosing.
