It is important that the vehicle can't be started when the user and therefore the smart key is outside the vehicle. This is especially important at fueling stations where the user is very close to the vehicle. The internal LF field is allowed to overshoot by a maximum of 10cm to help minimise this risk. Maximum overshoot is usually found on the side windows where there is very little attenuation of the signal.These features include, but are not limited to, remote start capabilities, valet mode, panic mode, trunk release, a dual-zone impact sensor, and a starter kill. With a strong 3,000-foot range, one user who works at a prison found that the “remote started my vehicle from behind thousands of feet of concrete walls, metal doors, and razor-wire fence. I couldn't believe it.” It is important to remember that this product, like many other car alarms, does require professional installation.
Note: A valid passive key must be within one of the three external detection ranges. These are approximately 3ft (1m) from the front door handles and the boot.
The CPU sends a data stream to the radio frequency (RF) transmitter. The keyless remote is actually a radio. Karani, R.; Dhote, S.; Khanduri, N.; Srinivasan, A.; Sawant, R.; Gore, G.; Joshi, J.
