WELOCK Smart Door Lock Compatibility Checker
Before installing a WELOCK smart lock, it’s important to make sure your door meets the basic installation requirements. Let’s go through three simple steps to check if your door is compatible.
1. Check Your Keyhole Type
WELOCK smart door lock is designed for Euro Profile cylinders, one of the most common keyhole types in Europe and many other regions. Please compare your existing keyhole with the reference image provided. If the shape and size match the Euro Profile standard, your lock is likely compatible.
2. Check Door Thickness
Next, measure the thickness of your door, including any decorative panels or cover plates. WELOCK offers two model types:
For door thicknesses between 30–70mm
For door thicknesses between 50–100mm
Be sure to choose the right model based on your measurement. If your door falls within these ranges, you’re good to go.
3. Measure Door Backset (Edge Distance)
Finally, measure the distance from the center of your keyhole to the edge of the door — this is called the backset. To ensure the lock won’t block your door from opening, the backset must be greater than or equal to 40mm. Use a ruler or tape measure to confirm.
That’s it! If your door meets all three criteria, you’re ready to upgrade to a smarter, keyless lifestyle with WELOCK smart lock. Still have questions? Reach out to WELOCK support team with a photo of your lock and measurements — we’re here to help.
