What Causes the Keyless Entry Failure in Sagitar?
2 Answers
Sagitar's keyless entry failure is caused by magnetic field interference, severe key collision, and other reasons. The specific causes are as follows: Magnetic Field Interference: Since the smart key uses low-intensity radio waves, it cannot function properly under magnetic field interference. Frequently placing the smart car key and mobile phone together can lead to interference from the phone's frequency, resulting in malfunction. If the smart key receives high-intensity radio waves, it will excessively consume power. Therefore, avoid placing the smart key near devices like televisions or computers. Severe Collision: For smart keys, the most feared scenario is being dropped from a height, as the internal circuitry of the key has weak impact resistance and is prone to damage under severe collisions.
I've encountered the issue of the Sagitar's keyless entry system failing before, mainly due to a dead key fob battery—replacing it with a new one solved the problem. Another common cause is interference from high-power electrical devices, like parking near microwaves or high-voltage power lines, which weakens the signal. Sometimes, the door sensor gets stuck, or the car's own battery is low, affecting the system. I recommend regularly checking the key fob's battery level; if the indicator light dims, replace the battery in advance to avoid problems at critical moments. This system is convenient but delicate, so try to park away from interference sources to extend its lifespan. Also, always carry a spare key—if the system fails, you can still open the door in an emergency and avoid delays.
