To start the Changan CS55 when the remote key is out of battery, follow these steps: 1. Use the mechanical key to open the door; 2. Press the brake or clutch pedal; 3. Place the smart key at the bottom of the cup holder; 4. Once the ignition switch lights up, press it directly to start the car. The Changan CS55 is a compact SUV with the following dimensions: length 4500 mm, width 1855 mm, height 1690 mm, wheelbase 2650 mm, and a fuel tank capacity of 58 liters. It is equipped with a 1.5T turbocharged engine, delivering a maximum power of 115 kW at 5500 rpm and a peak torque of 225 Nm, paired with a 6-speed manual transmission.

I just encountered this situation too, with my Changan CS55 key fob running out of battery. Don't panic. There's a small button on the side of the key—press it to slide out the mechanical key blade, which you can use to open the driver's door. Once inside the car, place the dead key fob against the push-to-start button, ideally with the back of the key touching the button. Press the brake, hold the start button for a few seconds, and the car will start. This is a clever design—it allows the car to start via induction even when the key battery is dead. However, you should replace the battery as soon as possible. The battery model for remote keys is usually CR2032, which costs about 5 yuan at auto parts stores. Remember, don’t force the key open—the plastic clip can break easily.

As a driver who frequently takes long-distance trips, I've encountered the issue of a dead remote key fob several times. The Changan CS55 handles this situation quite simply: First, use the mechanical key at the end of the fob to unlock the car door. Once inside, place the entire key near the cup holder to find the induction area—the actual location is slightly in front of the gear shift. If you can't find it, press the key against the start button below the steering wheel, then press the brake pedal and hold the start button to ignite the engine. The principle is that the car has a low-frequency signal to detect the key chip. It's advisable to keep two CR2032 button batteries in the glove compartment for emergencies. You can replace the battery by prying open the key cover yourself. If the spare battery is too old and fails, you can still use the mechanical key to open the glove compartment to retrieve the backup battery.

Last week, my wife's CS55 key fob ran out of battery, and none of the buttons worked. Here's how I taught her to handle it: First, remove the metal strip from the key to unlock the door. Second, once inside the car, press the key directly against the start button with the logo side touching it. Third, press the brake pedal firmly and hold the start button for more than five seconds. Note: If the sensor isn't responsive, try rotating the key slightly to ensure better contact. The biggest risk during this process is accidentally hitting the dashboard, which could damage the sensor module. After starting the car, head to a 4S shop or auto repair shop as soon as possible—they can replace the battery in just two minutes.

With a decade of car repair experience, I'm well-versed in the keyless start system of Changan vehicles. When the key fob runs out of power, first check if there's a hidden mechanical key slot on the key head—press the release button to extract it. After opening the door, there's no need to search for an ignition keyhole; the CS55's start recognition zone is directly on the push-button start. Press the entire key fob firmly against the button with the lightning bolt symbol, hold it steady, then depress the brake pedal to start. Some mistakenly believe they need to insert the mechanical key into the dashboard, which can actually risk breaking the key teeth. After starting, check the dashboard for a flashing key icon—its presence indicates it's time to replace the battery. As a final tip, wipe the key's solar panel clean; solar charging helps extend battery life.

The emergency starting method is described in the manual when you first pick up the car: If the remote fails, disassemble the key and press the silver button on the side to pop open the casing and retrieve the metal key. Be careful not to get your hand pinched by the door latch when opening the door. Once inside, press the entire key against the one-touch start button like swiping a card, keeping it firmly in place for about five seconds, then step on the brake to start. Interestingly, the system can recognize the key chip regardless of the battery status. Also, be reminded not to scratch the car paint with the metal key—some people, in a hurry to open the door, have left white marks. As a backup, you can contact Changan Roadside Assistance; they can remotely guide you to bind a temporary electronic key via the mobile app to start the car.
