What to do if the trunk of Audi A4L cannot be opened from the outside?

[SanDawson]

Audi A4L trunk cannot be opened for many reasons, including the car is not unlocked, the car key is out of power, the car battery is dead, the trunk lock loses lubrication, the trunk lock is deformed, etc. The specific analysis is as follows: 1. Poor contact of the key battery: Reinstall the battery and see if the indicator light on the remote control is on. If not, replace the battery first, and then confirm whether it is a problem with the remote control itself. It may be due to long-term use that the conductive layer on the surface of the contact under the button is worn out, so that it cannot conduct electricity, causing malfunction. 2. Signal interference: Signal interference may also cause malfunction. Check whether it is signal interference. If there is a strong magnetic field nearby, you can use mechanical unlocking, put the key in the small square at the bottom of the radio and start it.
