Philips DDL720: Upgrading to Premium Palm Recognition Security

The Upgrade: Moving from Mechanical to Biometric

The client contacted us with a clear goal: they wanted to move away from carrying physical keys and upgrade their home's security to a truly modern solution. They selected the Philips DDL720-MVP-17HWS, one of the most advanced locks on the market.

Before the transformation began, the door was fitted with a standard, dated mechanical handle that provided basic security and zero convenience.

Here is the original setup:

The Challenge: Precise Preparation

Installing a fully automatic, high-tech lock like the Philips DDL720 requires careful preparation, especially when retrofitting a door with existing cutouts. After removing the old handle, we began the necessary professional mortising to accommodate the new, much larger and more robust lock body.

This step is crucial. The preparation ensures that the lock sits correctly and operates flawlessly for years to come.

Here is a look at the door prepared for the new hardware:

Next, we precisely insert the new mortise body, making sure the alignment is correct for smooth latch and deadbolt operation:

The Process: Seamless Integration

With the groundwork laid, the main lock unit can be seamlessly integrated. We carefully align the internal and external panels, ensuring all cables are correctly connected and the overall fit is secure. For retrofits, we take extra care to ensure any previous installation marks are covered by the new, elegant plates of the DDL720.

The installation takes shape (View from the inside):

The Result: Flawless Function and Style

The final result is stunning. The sleek, black aesthetic of the Philips DDL720 instantly elevates the curb appeal of the home. The client gained multiple advanced access methods, including Palm Vein Recognition (one of the most secure and convenient biometric tech available), 3D Face Unlock, and robust smartphone app management via Wi-Fi. It's a true flagship upgrade in every sense.
