The functions of the Oshan X5 key include: automatic locking while driving, unlocking when parked, and remote window control via the key. Taking the 2021 Changan Oshan X5 1.5T DCT Elite model as an example: The manufacturer of this car is Changan Automobile, classified as a compact SUV, with a gasoline energy type, and a 7-speed dual-clutch transmission. The body type is a 5-door, 5-seat SUV. The car's dimensions are 4490mm in length, 1860mm in width, and 1580mm in height, with a wheelbase of 2710mm. It features a turbocharged intake form, front-wheel drive, a front suspension type of MacPherson independent suspension, and a rear suspension type of torsion beam non-independent suspension.

I previously researched the Oshan X5's key fob, and it's quite feature-rich, going beyond simple lock/unlock functions. The most basic functions are remote door unlocking and locking, operable from dozens of meters away, which is quite convenient. It also features a keyless entry system that automatically senses your approach and opens the door without needing to take out the key. There's a dedicated trunk button that opens just the tailgate, which I frequently use when shopping. Additionally, some models support remote engine start and air conditioning activation, making winter preheating hassle-free. The key contains an anti-theft chip with encrypted signals to deter thieves. If the battery dies, you can still use the mechanical key to open the door; typically, the CR2032 battery lasts several years. Remember not to soak it in water and to periodically check signal stability. Overall, the design is very user-friendly, aligning with modern smart car trends.

When I first started using the Oshan X5, I quickly got familiar with the key. The basic functions include one-touch unlocking and locking, all handled with a remote button. There's also a dedicated switch for the trunk, making it effortless to open and load luggage. The key automatically recognizes and unlocks the car when nearby, eliminating the need to search for the keyhole. Additionally, it has remote functions, allowing you to start the engine in advance to warm up the car, avoiding cold starts in winter. The key battery is a coin-type, which you can replace yourself when needed, but avoid frequent drops to prevent damage. If the key is lost, it's recommended to contact a 4S store to get a new one to prevent misuse by malicious individuals. I use this key daily for commuting—it's highly reliable and simple to operate, even for beginners. For maintenance, avoid strong magnetic fields that could interfere with the signal.

After test driving the Oshan X5, I found the key fob really impressive. Unlocking and locking the doors is effortless—just press a button, and there's even a separate button for the trunk. The keyless entry system detects your approach and opens the door automatically, which is super cool. Some higher-end models even support remote engine and air conditioning start-up, making it convenient to cool down the car before driving in summer. The waterproof and shockproof design of the key is great—no worries if it's tossed in your bag daily. The battery typically lasts about two years, and when replacing it, be careful not to reverse the positive and negative poles. Always keep a spare key with you, as it would be awkward if the main key gets left in the car. These small features enhance the driving experience, making it more enjoyable and carefree.
