Reasons for the Failure of One-Button Start in the 2006 Crown Model
2 Answers
Here are the reasons why the Crown's one-button start may fail: 1. The steering wheel is occasionally in a locked position. The solution is simple: just turn the steering wheel forcefully while turning the key, and the steering wheel lock will usually release quickly, allowing the ignition to happen instantly. 2. The gear was not returned to the P position when parking. If the car could start in D or R gear, the sudden movement of the vehicle at ignition would pose a significant safety hazard. Therefore, manufacturers preset this mode for automatic transmission vehicles. 3. Sometimes, the one-button start may encounter issues due to a weak smart key battery. Even though the key is inside the car, the dashboard may still display a warning.
I'm so annoyed by the one-touch start issue with my 2006 Crown. After driving it for over a decade, occasionally the button wouldn't respond, which turned out to be caused by the smart key battery running out. It worked fine after I replaced it with a new one. If that doesn't solve the problem, it might be due to the key sensor's positioning—the antenna under the steering wheel tends to accumulate dust or get blocked by interference; cleaning it should help. The start button itself might have poor contact or wear out over time, so it's necessary to check if it's stuck or broken. The car's anti-theft system could also be falsely activated, especially during rainy days when sensors get damp or the key signal is interfered with by a phone. For safety, I always carry a spare key for emergencies and regularly inspect the electronic components to extend their lifespan.
