What are the reasons why the remote control door cannot be opened?

[VonCole]

Generally, there are two possibilities: the car battery is low on power, or the key in your hand is out of battery. In this case, no matter what subsequent steps are taken for handling or repair, we first need to use the spare mechanical key to open the car door. First, check whether the indicator light on the remote flashes when unlocking. If it does not flash, the problem lies with the remote itself. If it flashes but the vehicle's central control does not respond, troubleshoot the unlocking circuit of the central control lock. The solutions are as follows: ① Use the key to lock the driver's door and check if other locks are engaged. ② Remove the main driver's door panel and inspect whether the electromagnetic lock inside is in the correct position. ③ Check if there is any issue with the metal rod inside the car door.
