Aqara Adjustable Cylinder for Smart Lock U200

Never locked out again 🔐 – the cylinder that fits every door

Do you have a front door without an emergency function? Or are you looking for a cylinder that flexibly expands with your door? The Aqara U200 Adjustable Cylinder is the perfect complement to the Aqara Smart Lock U200 – the adjustable smart cylinder that fits virtually any European door and guarantees access at all times.

Universally adjustable

The cylinder fits almost all European doors and is adjustable from 62 to 132 mm total (exterior: 30–60 mm / interior: 30–65 mm), in 5 mm increments. The minimum size is 35–35 mm, making the cylinder suitable for almost all standard Dutch doors.

The emergency function that really makes the difference

What makes this cylinder unique is its built-in emergency function : even if there's a key inside the lock (as is the case with the U200 Smart Lock), you can simply open the door from the outside with a key. This prevents you from locking yourself out – ideal for families and rental properties.

Easy DIY installation

The cylinder comes with everything you need for a quick installation without a professional:

• 🔑 4 keys included
• 🔧 Cylinder adapter × 1
• 🔩 Allen key set × 1
• 📏 14 extra reinforcement bars
• 🧩 External spacer kit × 8
• 🔗 Sliding rod set × 1
• 🪛 Cylinder locking screw + screw set

Sample automation

💡 Practical scenario: Set the door to automatically lock when the last occupant leaves the house (via presence detection).
