Why doesn't the car remote key work?

[LeVivienne]

Here are the reasons why the car remote key fails: 1. The car battery is dead, causing the vehicle to fail to receive signals; the car remote key has no power, making it impossible to unlock the doors. 2. The car remote control failure is due to the presence of high-power radio signals of the same frequency in the surrounding area, which prevents the vehicle's frequency signal receiving device from detecting the radio code commands sent by the remote key, leading to the car remote control malfunction and resulting in the inability to lock or unlock the doors. 3. Large outdoor LED displays, wireless callers for construction elevators at construction sites, wireless video surveillance equipment, etc. When certain hardware of such devices malfunctions, they generate multiple continuous radio stray signals that can interfere with nearby car remotes, causing the car remote to fail.
