If you sell smartphones on installments, you may have heard about Google DLC. Many retailers and device financing companies search for it when looking for a secure way to manage financed Android devices.
This guide clearly explains what the Device Lock Controller (DLC) is, how it works, who can use it, and what you should know about it.
What Is Device Lock Controller?
DLC (Device Lock Controller) is a device locking solution built by Google. It allows approved organizations to remotely lock and unlock Android devices, only for approved device financing programs. It is designed for large enterprises that buy devices in bulk and offer them to customers through financing programs.
How Does DLC Work?
DLC is integrated directly into supported Android devices through approved OEM partnerships, with the OEM controlling the final approvals on DLC enablement, usually based on agreed models and MOQs, with the enterprise that’s going to offer financing.
When used in a device financing program:
- The device can be locked remotely if payments are missed
- The device can be unlocked once payments are cleared
- The solution is enforced through Android’s built-in framework
What Features Does Device Lock Controller Offer?
Remote lock and unlock functionality
Strong security control
System-level enforcement
Integration through approved System Integrators (SI)
However, coverage depends on country availability, OEM partnership, Google approval for each enterprise, model compatibility, minimum monthly commitments to the OEM, and commercial agreements with the SI. It is not automatically available on all Android phones.
Who Can Use DLC?
DLC is generally available via its SIs to approved enterprises that buy devices in bulk & plan to offer financing, operate in approved countries, work with partner OEMs, abd buying compatible & enrollable models.
It is not usually accessible to small or independent retailers directly. Access typically requires formal partnership agreements, compliance approval, technical integration capability, and significant device volumes.

What Are the Alternatives to Google Device Lock Controller?
If the Device Lock Controller is not accessible due to country, volume, or OEM limitations, retailers often explore OEM-based device lock platforms or retail-focused device financing software.
For example, platforms like Smart Mobile Finance (SMF) are designed specifically for retailers selling devices on installments. Unlike OEM-dependent models, SMF’s device lock works across all Android devices and allows retailers to manage devices and repayment tracking without requiring factory-level integration.

Retailers that do not meet these criteria often explore independent solutions like SMF’s device lock, which is designed to be deployed directly without requiring OEM-level agreements.
No. It only works on supported devices from participating OEMs.
No. It must be integrated at the manufacturing level by the OEM. But SMF’s device lock app can be deployed at the retail level, depending on the implementation model.
