How to start the Changan CS75 when the key fob battery is dead?

Mechanical key, hidden inside the back cover of the smart key. You need to press and slide open the back cover to reveal the mechanical key. After opening the back cover, pull out the key. Use the mechanical key to open the car door, then place the smart key near the sensor. For some models, the sensor is located in the cup holder, while for others, it's near the one-touch start switch. The vehicle will detect the key and allow you to start it. Once placed in the correct position, the vehicle can be started normally even if the smart key battery is dead.

I also encountered a dead key fob situation with my Changan CS75. The solution is quite straightforward: First, locate a small button or slider on the remote key, press it to pull out the hidden mechanical key inside. Then go to the car door—there’s usually a small cover on the handle that needs to be pried open to reveal the keyhole. Insert the mechanical key, turn it, and the door will unlock. Once inside, don’t rush to start the car. If the key battery is weak, the start button may not sense it, so place the entire key close to the button or in the center console’s induction area (designed near the button), press the brake pedal, and then push the start button to ignite the engine. I recommend changing the key battery regularly to avoid embarrassment during long trips—the battery model is usually CR2032, which costs just a few bucks at stores. If the car still won’t start, try adjusting the key’s position or checking the manual for specifics. In short, don’t panic—the backup method works reliably.

I still remember one winter when the key suddenly failed, almost making me late. If your key runs out of battery, don't panic—the CS75 has an emergency solution: use the mechanical key to unlock and enter the car, then the key step is to hold the key close to the start button for a few seconds to sense it, press the brake, and press the button to start—this design is specifically for dealing with a dead battery. I believe prevention is better than a last-minute fix, so I change the key battery every year and a half to avoid hassle, otherwise, it might cause delays or even prevent you from opening the door. The operation is simple and safe, but make sure the surroundings are clear—don't try it recklessly in traffic. Lastly, remember to get genuine batteries from a 4S store or auto parts shop to avoid counterfeit products damaging your car.

CS75 Key Battery Depletion Starting Method I understand clearly: First, use the mechanical part to open the car door. After entering the cabin, hold the key close to the start button (the sensing area is usually below the button), press the brake, and then press to start. This method can basically solve the urgent problem. After solving it, replace the battery immediately. For prevention, pay attention to the key's response speed slowing down and take action promptly.
