Worth it—if your deadbolt fits
Worth it or skip it?
Worth it if
- Your standard deadbolt bore is under 54 mm and you want hub-free remote control with multiple advertised entry methods.
Skip it if
- You haven't confirmed that your door uses a compatible standard deadbolt with a bore under 54 mm.
Key facts
Compatible deadbolt boreThe listing describes fitting most standard deadbolts and bores under 54 mm; measure your existing hardware first.
The fit-first verdict
Choose it when your door has a compatible standard deadbolt with a bore under 54 mm and you want remote app control without a hub. Confirm the hardware fit and Wi‑Fi reach before ordering.
Buy on AmazonAt the front door
You stand at the entry, choosing a fingerprint, code, phone, key, watch, or voice instead of hunting for one key.
What the design changes
This T8506 is a single front-door deadbolt with built-in Wi‑Fi, so its eufy app control does not need a separate bridge. It is designed for most standard deadbolts and bores under 54 mm, with the replacement exterior and interior hardware supplied.
Measure first: hub-free access only helps if this deadbolt can replace your existing hardware.
Before you choose
Does the lock require a separate bridge or hub?
No. The seller says the T8506 has built-in Wi‑Fi and works through the eufy Security app without a bridge.
What comes in the package?
The listed components include two keys, eight AA batteries, exterior and interior assemblies, an installation set, and a mounting plate.
Is this a complete door?
No. It is one eufy Security deadbolt for apartment, office, front, entry, or exterior doors.
