CLIFFORD Car Jacking module
Carjacking Response & Vehicle Recovery System
BlackJax is Clifford’s unique anti-carjacking response system that puts personal safety first while using innovative advancements to ensure that users can recover the vehicle themselves. If an armed car thief approaches – whether at a stoplight or in a parking lot (where most carjackings occur) – immediately turn over the keys and remote and let Clifford technology take over.
BlackJax is fully automatic: no buttons or transmitters to push when a weapon is involved. Just get away from the vehicle. BlackJax allows the criminal to drive away a safe distance. Then, a few seconds later, BlackJax blares the siren and flashes the lights to alert other drivers and witnesses. It then pulses down the ignition system to safely force the vehicle to slow to a complete stop. Siren blaring and lights flashing, unable to restart the engine, the carjacker has no choice but to abandon the vehicle.
BlackJax uses a unique PIN code that the owner has to enter within 30 seconds of the vehicle moving when the ignition is turned on, or a door is used (preventing carjacking whilst the key is in the ignition); if this code isn't imputted the Clifford Immobiliser system will jump to work. 
BlackJax offers immediate vehicle self-recovery. With the vehicle immobilized a short distance away, the owner can recover it. No special tracking units, monthly fees or per-use charges. Just follow the sound of the BlackJax siren, then enter the PIN code. That’s it – it’s sabotage-proof. The only way to turn off BlackJax is with a secret user-selectable PIN code. If the carjacker tries guessing codes at random, BlackJax actively ignores his code entries for the next few minutes. Even if they were to find and remove the BlackJax control unit, they would still be unable to restart the engine.
 
     That’s Clifford technology you can count on.
