The Best Password Protected Thermostats

While there are several lockable thermostats out there, not all of them feature password protection. By password protection, I mean a thermostat that can be locked with a unique code, and you need to enter the code to unlock the unit.

Although a lockable thermostat that doesn’t feature password protection can prevent tampering, unauthorized persons may unlock it, as it doesn’t require a passcode to unlock.

To be sure that your thermostat is completely protected from unauthorized access, you want to get one with password protection features. Sounds like you? Then keep reading as I’ve featured some of the best password-protected thermostats in this post.

Best Password Protected Thermostats: Features

1. Honeywell TH9320WF5003 Wi-Fi Thermostat

If you’re looking for a thermostat with password protection functions, this is one of those that tick all the boxes. This Honeywell thermostat allows you to set a unique code for locking and unlocking the unit, which ensures total protection from tampering.

And if you just want to lock some features on the thermostat, you can do that with the partial lock function. What this means is, the thermostat features two locking modes—partial lock and full lock.

With partial lock, you can prevent access to some settings while anyone can access the rest of the features/setting. And with full lock, all features/settings are prevented from unauthorized access.

For lost/forgotten code, you’ll have to restore default factory settings on the thermostat or call Honeywell Customer Support for help.

If you forget the password, you can log in to your account on ecobee’s website and disable the password. If you’re not sure how to go about that, simply call ecobee Customer Support for help. You’ll need to verify your identity and they’ll send you a reset code.

Why Should You Lock Your Thermostat?

As mentioned, locking a thermostat helps prevent accidental or unauthorized changes to the settings.

For instance, your children or employees (for business owners) may make changes to your thermostat settings that could increase your energy bills. But you can prevent this by locking the thermostat.

Are Keypad Lockout/Password Protected Thermostats Worth It?

Yes. Here are some benefits of using keypad lockout/password protected thermostats:

No Lock Box

While you can protect a thermostat from tampering with a lockbox, it changes the comfy look of your home or business. Instead of having that unappealing box on your wall, get a thermostat with a locking function. Of course, it ensures unauthorized access and maintains the comfortable and inviting look of your home/business.

No Worries about Energy Cost Increase

With your thermostat protected with a password, your schedules will remain the same way you left them. So no worries about your family, customers, or employees tampering with the temperature settings, which may increase your energy bills.

Reduces the Need for Unexpected Expensive Service Call

Accidental changes to settings can sometimes cause problems that require the services of an expert. But keeping your thermostat lock prevents accidental changes to your settings, thus minimizing the need for an expensive service call.
