What are the functions of the LaCrosse car key?
2 Answers
LaCrosse key functions include: Lock button: The new LaCrosse series is equipped with an anti-theft alarm function. Pressing the lock button once locks the car, and pressing it twice activates the anti-theft function. Trunk opening button: The trunk can be opened directly whether the car is locked or unlocked, and closing the trunk does not affect the locked status. RES button: After each remote start, the engine can run for 10 minutes, which can be extended by another 10 minutes. During the first 10 minutes of engine operation, following the remote control steps again can extend the time by another 10 minutes. Car finder button: Pressing this button will trigger an alarm sound.
I've been driving the LaCrosse for two years, and the key fob is quite feature-rich. The top button is the unlock key—a single press opens all doors; the middle one locks the car for security; the bottom button controls the trunk, releasing it effortlessly with one click. Holding the panic button triggers flashing lights and honking, super handy in crowded parking lots. Some models support remote engine start—like holding the lock button for seconds to preheat or precool the cabin, eliminating summer heat soak. It also has keyless entry, auto-unlocking doors upon approach without button hunting. Just avoid pocket presses (especially forgetting CR2032 battery swaps to prevent malfunctions)—I routinely clean the key slot to keep dust out. Overall, its human-centric design ensures intuitive operation.
