What are the functions of the Besturn B70 key?

Clicking the unlock button once can open the car door, clicking the unlock button can lower the windows, and holding the lock button can close the windows. Precautions for ordinary car keys: After ignition, the key should be released immediately. If held for a long time, it may damage the engine belt. Avoid hanging the car key together with other keys or accessories. Precautions for smart car keys: Smart keys use low-intensity radio waves, so they should not be placed near electronic devices. Avoid rough handling, as the internal circuits of smart keys are not highly resistant to impact and can be easily damaged by severe collisions.
As an enthusiast of automotive technology, I particularly love the design of the Bestune B70 key fob. It mainly features three standard buttons: the unlock button opens the doors immediately when pressed, the lock button automatically locks the doors and folds the mirrors with a single press, and the trunk button directly opens the rear hatch for easy access. If the model supports smart features, it may also include a remote start button to preheat the engine or turn on the air conditioning in advance. The key fob also integrates a keyless entry system, allowing the doors to unlock via proximity sensing, and the start button ignites the engine without needing to insert the key. The car locator function, activated by holding the lock button, flashes the lights and honks the horn, which is super practical in parking lots. The battery is a CR2032 coin-type and may deplete after a year or two, leading to malfunction. I recommend keeping the key fob dry, avoiding placing it near phones to prevent signal interference, and regularly checking button responsiveness to avoid security system failures.
