FLEX™ saves you time and money
The handheld device, which is about the size of a smartphone, has a sleek, stylish design with an intuitive interface. During the pre-calibrated FLEX-Cal module replacement process, the FLEX headset is never removed, ensuring that the licensed technician’s original device configuration remains intact and state required calibrations happen in seconds.
FLEX is powered by our patented FLEX-Cal™ technology which enables the pre-calibrated module to be quickly replaced in a contactless fashion.
No other Ignition Interlock provider offers that
level of convenience.
It’s as easy as changing a battery
We’ll ship you a new module when your monitoring authority requires it to be
replaced. It only takes a few seconds to:
Unlock the module at the back of the device.
Remove the module by lifting on the tab at the bottom.
Insert the new module into the device and lock it into place.
Then return the old one to us with a preprinted label. It’s that simple.
For nearly 30 years, our Ignition Interlock Devices have been known for easy, dependable operation and intuitive design. But FLEX takes Ignition Interlock to a whole new level.
Its futuristic style fits naturally and discreetly with any car interior. FLEX is designed to be compact and comfortable in your hand. And its simple, three-button interface offers the easiest operation of any Ignition Interlock on the market.
