Methods to open a car door without the key are as follows: 1. Contact a professional locksmith from a nearby auto shop to assist with unlocking. Before unlocking, you need to provide your driver's license and relevant vehicle documents to the professional to prove ownership of the vehicle. 2. Break the rear or passenger-side window to open the door. In remote areas where no other options are available, you can use a stone to break the rear or passenger-side window to gain access. However, replacing a broken car window can be costly. Key maintenance tips: 1. Do not leave spare keys inside the car. If a smart key is lost due to poor maintenance, it can cause significant inconvenience, and the cost of re-matching is high. 2. Avoid placing the key near electronic devices. Generally, the original battery of a smart key lasts about two years, but severe electromagnetic interference can cause the key to malfunction. 3. Keep the key away from metal objects. Contact with or coverage by metal items may cause the smart key to malfunction. Additionally, other items in a bumpy environment could damage the smart key. 4. Never use the wrong battery. Be cautious when replacing the battery of a smart key; any mistake could burn out the circuit board inside the key. It is advisable to have the battery replaced at a professional 4S shop.

What is the Replacement Interval for Engine Belts?

Engine belts should typically be replaced every 60,000 kilometers. Below is additional information: 1. If the vehicle is used in harsh environments, such as areas with heavy sandstorms or high temperatures, replacement may be needed around 50,000 kilometers. Extreme temperatures can accelerate rubber aging, so vehicles operating in very hot or cold regions may require earlier belt replacement. To determine the exact timing, carefully inspect the timing belt for wear and decide accordingly. 2. Owners can manually check the belt by touching its surface to see if it has become rough. Additionally, pressing the belt can help assess its elasticity and stiffness. If the belt feels rough, use a flashlight or phone flash to examine the surface and edges for persistent white marks. If large white areas or cracks are visible, immediate replacement is necessary. Even without whitening, if the belt lacks flexibility, it should also be replaced.
