How to Remotely Lock Smart TV from Your Phone
With Cylux, you can lock your child's Smart TV instantly from anywhere — no need to be in the same room or even the same city.
Why Remote Lock Matters
Picture this: you're upstairs, your child is watching TV downstairs, and you said "ten more minutes" twenty minutes ago. With Cylux, you don't need to walk downstairs, argue, or grab the remote. One tap in the parent app locks the Smart TV in seconds — from anywhere with internet.
How to Lock Smart TV Remotely
- Open the Cylux parent app on your iPhone or Android phone.
- Tap your child's Smart TV device from the device list.
- Tap the Lock Now button (the padlock icon).
- The Smart TV shows a full-screen lock message within 3–5 seconds.
To unlock it, tap Unlock in the same screen. You can also set an automatic unlock time so the TV comes back on for allowed viewing periods.
Locking on a Schedule
If you want the TV to lock automatically at 9 PM every night without you having to remember, set a Bedtime Schedule:
- Go to Schedules → Add Schedule.
- Choose the days and time range (e.g., 9 PM – 7 AM).
- Label it "Bedtime" and save.
The Smart TV locks automatically at 9 PM and unlocks at 7 AM, every day you specified. No manual action needed.
Locking During Homework or Dinner
Add a second schedule for homework time (e.g., 3:30 PM – 5:30 PM on weekdays). Cylux will lock the TV automatically during those hours so there's no temptation while your child should be studying.
What Happens When the TV Is Locked
The Smart TV displays a friendly lock screen with a message you can customize — like "Time's up! Come have dinner." The remote stops working for content navigation. The device doesn't shut off, so there's no disruption to downloads or updates.
Works Even When You're Away
The remote lock works from anywhere — you don't need to be on the same Wi-Fi network. Cylux routes commands through its cloud, so you can lock the Smart TV from work, from a restaurant, or from another country.
Frequently Asked Questions
What if my child unplugs the Smart TV to bypass the lock?
Cylux re-applies the lock as soon as the device powers back on and connects to the internet. The time spent offline doesn't reset the daily limit.
Can I lock individual apps instead of the whole TV?
Yes — in the App Controls section you can block specific apps (like YouTube) while leaving others (like Netflix) available.
