Can Roewe Keyless Start Be Used When the Key Fob Battery Dies?

[VonSteven]

When the Roewe key fob battery dies, you can use the mechanical key; for models equipped with a one-button start function, simply place the key in the induction area and then press the start button to start the car; replace the key battery before starting. Using the mechanical key to start. Generally, the mechanical key is hidden inside the remote key fob. By pressing the top button of the remote key or sliding it, you can remove the mechanical key to start the car. If you need to replace the remote key battery, you must first remove the mechanical key before prying open the remote. When the remote key fob is running low on battery, it will exhibit the following symptoms: Shortened remote range: If the car can normally be controlled within 3 meters when fully charged but suddenly requires you to be very close to the car to operate the remote, the key fob may be out of power. Key malfunction: If pressing the key repeatedly yields no response and there is no external magnetic interference, the remote key fob likely has no battery left. When the remote key fob runs out of battery, you can purchase a corresponding model of button battery, pry open the remote with a coin, replace the battery, and then reassemble it as before.

I had this happen with my Roewe key fob when the battery died. The push-button start still worked as long as I pressed the key against the ignition button. At that time, I pressed the back of the key directly on the start button and held it for a few seconds to start the car. Actually, there's a backup induction area in the car, usually under the cup holder or near the center console—just try different spots. But remember, if the key is completely dead, the remote locking won't work, and you'll have to manually unlock the door. I recommend keeping two CR2035 button batteries in the glove box—they cost just a few bucks online and are easy to replace; just pry open the key shell and swap them. Pay attention to weakening key signals as a sign to change the battery soon.

I've driven Roewe for over a decade and I'm quite familiar with starting the car when the key fob battery dies. Just hold the key close to the start button and keep pressing - most times it'll fire right up. Some cars have the sensor area inside the center console, the manual shows the exact spot. Last winter when my key suddenly failed, this trick saved me. Changing the battery is super easy - just pop open the key cover with a coin. Pro tip: while the key chip drains power slowly, it's best to replace batteries every two years, especially for smart keys. The signal ring around the start button can detect the chip inside the key, so it works even without battery power.

You can still start the car with one button even if the key battery is dead. The start button of Roewe vehicles can detect the key chip—just press the key against the button to attempt starting. Last time my wife encountered this situation, she solved it by touching the key directly to the button. The key point is that the key must be pressed tightly against the starting area. Replacing the battery is crucial—don’t wait until it’s completely dead. The sensing position may vary slightly depending on the model; some may sense it in the glove box or armrest area. Don’t panic—just try different spots, and it’ll work.

I once encountered a dead battery in my Roewe key fob. The one-button start function still worked by pressing the key fob tightly against the start button. Last time in the parking lot, it took me three attempts to succeed - positioning is crucial. Reminder: regularly observe your key fob's remote control distance; if it shortens, replace the battery immediately. At auto parts markets, a battery replacement only costs 5 RMB and can be DIY-ed. The principle is that the car's radio frequency coil can activate the key chip even without battery power. Remember to press the brake pedal and hold the start button when igniting.

I just replaced the battery in my Roewe key last week. When the battery is dead, the one-button start can still work in an emergency, but the key needs to be placed close to the start button. The location varies by model—I've tried both the center console and the cup holder area, and both worked. The principle is quite clever: a weak current activates the key chip when starting the car. By the way, about the battery, it costs 30 yuan to replace at the 4S shop, but you can buy the same model battery yourself for just 2 yuan. It's a good idea to keep a spare battery in the car, especially for older car keys. Starting the car this way is only a temporary solution; replacing the battery as soon as possible is the reliable way to go.
