BenjiLock Replaces Keys with Fingerprint Security
BenjiLock created the world's first traditional padlock with fingerprint technology. Touch to unlock, or use a backup key when needed, with no apps required.

When Forgetting a Combination Means Cutting the Lock
Most people have dealt with a forgotten padlock
combination at some point. You stand at the gym locker or storage unit, trying
numbers until you give up and grab bolt cutters. Robbie Cabral, a
Dominican-American entrepreneur in Los Angeles, experienced this frustration at
the gym one day in 2014. He wondered why padlocks still required remembering
numbers or carrying small keys when fingerprint technology already existed in
phones. That same day, he got laid off from his job, and his daughter was born;
he started designing a better solution.
The result was BenjiLock, a padlock that opens
with a fingerprint touch but keeps a traditional key backup. The hybrid
approach means you're never locked out—if the battery dies or the fingerprint
sensor has issues, the physical key still works. The design gained commercial
attention, leading to retail distribution. The product line expanded from basic
padlocks to bike locks, travel locks, and door locks, all using the same
dual-access technology.
How the Fingerprint System Functions
The fingerprint sensor sits at the top of the
lock body and recognizes stored prints through capacitive touch technology.
Users register fingerprints by holding a programming button while scanning
their finger multiple times. The internal memory holds up to ten different
fingerprint profiles. When someone touches the sensor, the lock compares the
print against stored data and releases the shackle mechanism if a match occurs.
The entire recognition process takes approximately one second.
The lock maintains a traditional key cylinder
alongside the electronic system. If the rechargeable battery depletes or the
sensor malfunctions, the mechanical key provides alternative access. A USB-C
port on the lock's base connects to standard charging cables. Battery life
varies by usage frequency but typically extends beyond twelve months between
charges. The locks function independently without requiring smartphone apps,
wireless connectivity, or external servers for operation.
Technical Implementation and Product Range
Different models address specific security
applications through variations in size and construction materials. Outdoor
versions use stainless steel bodies with IP68 waterproof ratings and operate
across temperature ranges from negative conditions to high heat. Travel models
comply with TSA specifications, allowing security personnel to open them with
master keys. Bike lock versions incorporate U-shaped hardened steel shackles.
All variants use the same fingerprint recognition system and dual-access design, combining biometric and mechanical entry methods.
The company produces locks ranging from small
luggage models to heavy-duty commercial padlocks. Each lock stores fingerprint
data locally within the device itself. No wireless transmission occurs during
normal operation. The capacitive sensor reads the unique patterns in
fingerprint ridges and compares them to enrolled templates stored in
non-volatile memory. The mechanical key system operates through a standard pin
tumbler mechanism independent of the electronic components.
