What are the reasons why a keyless start car won't start?

Reasons why a keyless start car won't start: 1. The steering wheel is locked. In the locked state, the keyless start function won't work. Solution: Turn the steering wheel left and right while pressing the engine start button to release tension and unlock the steering wheel. 2. The battery has insufficient voltage, is dead, or is damaged. Solution: You can jump-start the car with another vehicle or push-start it (manual transmission cars cannot be push-started). 3. The remote key is low on battery. Solution: You can pull out the mechanical key, find the remote key slot in the car (often hidden in places like the center console), insert the remote key, and then start the car. Alternatively, you can press the remote key against the start button and then press the start button to start the car. Afterward, replace the remote key's battery.
The same thing happened to my car that day—the push-button start didn't respond, which gave me quite a scare. After checking for a long time, I found there could be multiple reasons: First, the car battery might be dead or aging. Most push-button start systems nowadays rely on electrical signals to ignite, so if the battery is drained or the terminals are loose, it won't work. In my case, it turned out the battery had reached the end of its lifespan, but jump-starting got it going. Second, it could be an issue with the key—if the key fob's battery is dead, the car won't sense it to unlock. Just replace the coin battery inside. Third, the anti-theft system might have locked out the start function, like if a door wasn't properly closed or there was signal interference causing a false security threat. Otherwise, it might be a faulty starter motor or alternator problem. My emergency fix was getting a jump-start, then heading straight to the repair shop for a full checkup to avoid getting stranded next time. My advice: keep an eye on your battery's health—don’t wait until the last minute like I did.
