2 Answers
Besturn X80 vehicle authentication failure. Vehicle authentication failure: It is related to the key and engine anti-theft system. The anti-theft system cannot correctly read the data of the anti-theft chip in the key or cannot parse it. The reason may be a software problem or a hardware problem. If it only occurs on 1.8T vehicles, the chance of a software problem is greater. The smart key is not recognized, the key chip is lost or damaged, the key battery is low, or the internally stored PIN code is not locked/matched incorrectly. Consequences of Besturn X80 vehicle authentication failure: The car will not start because the key does not match. In this case, the rider should go to the 4S store to re-match the key to start the engine. The X80 is Besturn's compact SUV, equipped with two engines, one is a 1.8-liter turbocharged engine, and the other is a 2.0-liter naturally aspirated engine, 1.8-liter turbocharged.
When driving my Besturn X80, I encountered authentication failure, simply put, the car doesn't recognize the key or remote commands. It often shows an error prompt during startup, which is quite annoying. The most common reason might be a dead key battery, so try replacing it. Additionally, if the key is in your pocket and blocked by other items, the signal could weaken; failed system software updates can also cause bugs, making the vehicle's anti-theft module unable to recognize the key. Sometimes it's just a temporary issue—try restarting the vehicle or removing and reinserting the key. However, I recommend first visiting a 4S shop to have a technician check it with a professional diagnostic tool. They can quickly determine whether it's a software bug or a hardware fault, such as damage to the anti-theft module or an antenna issue. Don't try to fix it yourself to avoid making things worse. In short, get it repaired as soon as possible to ensure driving safety and prevent it from disrupting your trip.
