Smart Key with Passive Keyless Entry System w Immobilizer System.
Features of Smart Key
The Passive Keyless Entry (PKE) System AKA Smart Key System is a new electrical product for vehicles. It is safer and more convenient for users
than the traditional RKE system. The PKE system uses RFID technology,
providing the highest security available.
Features
* Completely Passive Keyless Entry
* Automatic Door Locking (Arming)
* Automatic Door Unlocking (Disarming)
* Vehicle Immobilization
* Exhausted Battery Emergency Operation Mode
* Unclosed Door Warning
Main Functions
1. Passive Door Locking
By simply walking over 1.5 to 2 meters away from your car, doors will
automatically lock and ARM the security system.
2. Unlocks Doors Automatically
As you approach your vehicle and arrive in range of 1.5 to 2 meters, the
system will automatically identify the driver who has a valid access key
and unlock the doors immediately.
3. Immobilizer Function
The PKE system still includes an immobilizer function. It can provide the
user with the most comprehensive protection against vehicle theft. Once
users enter the vehicle and attempt to start it, the device will verify the
driver's access key. If a valid access key is identified, the LED will turn
off allowing the driver to start the vehicle. If not, the horn and lights
will sound and flash an alarm, and the vehicle engine can not be started.
4. Closes Windows Automatically - Optional
At the same time as locking the doors after the driver leaves, the system
will automatically close any windows that are left open.
5. Exhausted Battery Emergency Operation Mode
Even if the access key has low or exhausted battery power, or is damaged, it can still disarm the alarm and start the engine in a separate easy to use procedure. This function ensures the vehicle can be driven by the legitimate owner 100% of the time.
Other Function:
1. Hi-classify Safety
The highest level of security US made RFID core chip is used, and mutual
authentication is done between the access keys and the base which installs
it in vehicles, and also we used hopping code technology, making it
extremely difficult to crack the access key.
2. Convenient Access Key
The Access Key is very thin, only 6mm thick, and also only 2/3 of credit
card size. Easy to carry, can be put it in wallet, and need not be taken
out to use. Consequently it will be carried separately from other keys
providing added safety and convenience.?
3. Alarm Accuracy
The system will initiate alarm only when the vehicle has suffered real
violation, and will not be triggered by lightning or other harmless
influences.
4. Locks After First Braking
The vehicle door will be locked automatically when driver step the brake at first time after engine been started.
5. Unclosed Door Alarm
If driver leaves vehicle without closing a door or doors, the system will
let you know with a separate open door alarm when the key leaves the
contact range. Even if this alarm is ignored the car alarm will still be in
effect.
6. Low Battery Reminder
When the access key's battery is low, the system will automatically sound
the horn and flash lights to remind the driver to replace the inexpensive
and readily available battery.
7. Nullifies Frequency Jamming Devices
Some thieves use frequency jamming to jam remote controls, stopping the system from arming, so they can steal the vehicle. Our system can not be jammed and avoids the possibility of such theft. Even being jammed, the doors still will be locked.
8. Stops Code Scanner Yard Sweeping Dead in it's Tracks
Many thieves will use a code-scanner to sweep yards when drivers open or close vehicle doors by remote control, and copy signals to steal vehicles. The access key uses mutual authentication technology, and hopping code to avoid this.
