Smart key malfunctions may occur due to a dead remote battery or the vehicle being near signal towers or other interference sources, causing issues with the smart remote system. Reasons for smart key malfunctions: The remote battery is dead, preventing the car from unlocking during use; the parking environment is near interference sources like signal towers, disrupting the remote's infrared signal; or the smart remote system malfunctions, making it impossible to lock/unlock doors or recognize the smart key. Solutions: Push-to-start models usually have a smart key slot—some located inside the center console, others beneath the cup holder mat. Inserting the depleted key into this slot allows the vehicle to detect it and start. Some push-to-start models feature a physical keyhole. Insert the metal key blade from the remote into this hole to start the vehicle.

What are the models of scaffolding safety belts?

Scaffolding safety belt models include T1XB, T2XB, T3XB, T4XB, T1PH, T2PH, TPG, etc. T1PH Universal Type I Climbing Activity Belt: It is suitable for workers who need to climb high to prevent falls during climbing operations, such as working on top of chimneys, iron towers, or water towers. The user first fastens the safety belt, wears a movable climbing hook connected to the waist belt on each hand, alternately hooks the climbing hooks onto the ladder or other climbing objects, and always keeps one climbing hook attached to the ladder. In the event of a fall, the worker will be stopped. T2PH Universal Type II Climbing Activity Belt: This is a semi-open, semi-enclosed climbing safety belt. The difference from T1PH is that it has only one climbing hook, with the other being a closed safety hook. During use, the worker needs to first secure the safety hook and pulley hook midway, then attach the climbing hook, allowing the worker to pause and work midway. TPG Universal Climbing Fixed Belt: This is a climbing safety belt equipped with a self-locking hook. It is suitable for more complex work environments, such as climbing iron ladders on chimneys. A rope is fixed to the ladder in advance, which can be a synthetic fiber rope or a steel wire rope, with sufficient strength. When climbing, the worker only needs to connect the self-locking hook to the fixed rope, which serves as a limit and relative fixation, allowing the worker to climb freely upwards along the rope during operations.
