What is the reason why the Toyota Corolla remote control cannot unlock?

[CassidyFitz]

Reasons why the car remote key cannot unlock the car: 1. No power: There are usually two possibilities: either the car battery is low on power or the key itself is out of power. In this case, regardless of any future handling or repair, the primary task is to use the spare mechanical key to open the car door. 2. Remote damage: First, check whether the indicator light on the remote flashes when attempting to unlock. If it does not flash, the issue lies with the remote itself. If it flashes but the vehicle's central control does not respond, troubleshoot the central lock unlocking circuit accordingly. 3. Incorrect lock magnet position: Use the key to lock the driver's door and check if the other locks engage. Remove the front main driver's door panel to inspect whether the electromagnetic lock inside is correctly positioned and whether the iron pull rod inside the door is functioning properly.
