What Causes the Failure of Car Handle Sensor Lock to Open the Door?

[McAmara]

If the touch door handle fails to function, it is necessary to inspect the sensor contact switch of the door handle. Reasons for the failure of car sensor doors: If the car's sensor system fails due to a dead battery, recharging the car can resolve the issue. If the sensor key is out of power, you can use the spare mechanical key inside the sensor key to open the door, or simply replace the key battery. It could also be due to damage to the car's sensor door lock, in which case a detailed inspection at a repair shop is recommended. Precautions for using car sensor keys: When using the smart key, avoid placing it near electronic devices. Generally, the original battery of a smart key lasts about two years, but severe electromagnetic interference can also cause the smart key to malfunction.
