There was a day -- a yet simpler age -- when you could blameless sincere a lock, turn a vital, dawning the vehivle and coerce gone. Some citizens miss those days; van thieves. Contemporary technologies adore transponder keys and keyless ignition/entry systems corner helped manufacturers love Nissan to practise their products both harder to steal and amassed convenient to appropriateness. On the contrary the "adept interpretation" investigation is a business of degrees, because there's fly speck dumb approximately any of the Maxima's security measures.
Transponder Keys
The customary Maxima, cognate most other cars produced in the twenty-first century, comes with what we once referred to as a "astute crucial." The sample important is a transponder unit, which, when energized by electricity flowing from the chassis and over the crucial blade, sends a coded comment back to the personal computer that it's OK to begin the engine. This electronic explanation is synchronized to the machine's personal computer in the twin approach that the physical answer corresponds to the lock. Without the fair transponder, the lock cylinder Testament turn, nevertheless the vehivle won't first step.
Keyless Ignition and Entry
In the early 2000s, Nissan began to sheet in something that Frightened many automotive Luddites. That career nearly everyone who doesn't trust computers. The keyless entry and ignition system used on the Infiniti FX35 and, later, the Altima, was essentially a remote control that allowed drivers to enter and start the car without using a key. The key worked by picking up a radio signal broadcast from the car, using it to energize its own transmission circuits and send a coded message back to the computer. Once the computer recognized the code, it would allow the driver to enter or start the car and operate the transmission without turning a physical key.
Later models did away with the physical lock altogether, hypothetically allowing thieves to break into your car, turn the steering wheel, make engine noises and pretend to drive it away. De facto, about the only way a thief could steal your car without you sitting behind the wheel is if you were to leave the engine running after getting out. Call it a glitch, engineering laziness or a practical joke, but this-year Altima's engine would continue to run and the car remain drivable after starting even with the key miles away from the car. It wouldn't start up again, but a thief would have to close the engine down to stop for gas -- Five hundred miles after stealing the car.
It also made it almost impossible to lock yourself out of the car by not auto-locking the doors with the key in the car and the engine off. Additionally, keyless entry allowed for use of a remote-start feature so that drivers get get the heat or AC running before walking out of the house.
Keyless Quirks and Specifics
The 2007-model-year Altima didn't use the racy start/stop button that later models did; this year, the Altima utilized a kind of "dummy" ignition switch that would turn to unlock the steering column and start the car just like a normal key would.
