: Input unique user or group IDs alongside custom codes ranging from three to six digits long.
Once installation is complete, test the system functionality before placing the vehicle into service.
The KeySecure 3b handles up to thousands of PIN numbers locally without needing live radio signals, cell towers, or cloud connections to release keys.
Each KeySecure unit features a rugged, weather-resistant polyester powder coat finish. It can be mounted on heavy vehicle surfaces or flat interior walls.
Inspect the wiring harness for signs of brittle insulation, chafing, or thermal degradation caused by engine compartment heat. knox keysecure 3b installation manual hot
The unit requires a constant, unswitched 12V DC power source capable of handling a 2-amp peak draw during lock engagement. Mechanical Mounting Steps
Drill the four holes using a bit sized appropriately for your mounting screws or bolts (typically 1/4-inch bolts with locking nuts are recommended for heavy vehicle vibration). Drill a 1/2-inch hole for the wiring harness.
: The unit requires a 3 amp, 12-volt DC power supply.
Note: Tools required typically include a power drill, drill bits, socket wrench set, wire strippers, crimping tool, and a digital multimeter. 3. Mounting the KeySecure 3B : Input unique user or group IDs alongside
The heat radiating off the Knox KeySecure 3B wasn't just a temperature; it was a physical weight.
Ensure the unit is completely clear of all airbag deployment zones. Consult the vehicle manufacturer's modifier guide.
If mounting to a metal surface prone to heat conduction, use high-temperature rubber or silicone washers to create a thermal break between the unit and the vehicle body.

The master key is held in place electronically until a authorized PIN code is entered.
Ensure there is at least 3 inches of clearance behind the mounting surface to accommodate the wiring harness and prevent pinching.
Choose a secure, dry, and easily accessible location (typically inside a vehicle console, trunk, or a secure building area).
