You have a problem with the charging system.
I have that problem check the water level of your battery, i find if i top up battery water, the flashing stops.
The keyless lock might stop working on your Mitsubishi Lancer because the battery is dead or because there is a problem with the wiring. You might also have a problem if the brain or computer of the vehicle is damaged.
There is a problem with your charging system. May be a defective alternator or something else.
First guess; the battery is dead. If you replace the battery and that doesn't solve the problem, you may need to have the dealer reprogram the remote for your lock code.
A flashing charger light usually indicates a problem with the battery.
The light is flashing because there is a problem. The problem will need to be diagnosed and repaired to stop the flashing.
If it does that. Check your alternator. If you have no problem there. Check your battery charge. I'd check the battery charge first. If thats cool. I'd check the sensor. Cause it's telling you somethings wrong with your battery system. Good Luck.
It could be the remote has a dead battery. If both remotes don't work, seems like the sensing unit in the car has failed. The remote battery is the easier problem to fix.
The continuous flashing of a key sign typically indicates that the vehicle's key fob is not recognized or that the keyless entry system is malfunctioning. This can happen if the key fob battery is low, if there's a problem with the vehicle's ignition system, or if the key fob is out of range. In some cases, it may also signal that the vehicle is in a security mode, preventing it from starting. It's advisable to consult the owner's manual or seek professional assistance to diagnose the issue.
Where is it flashing? The screen? Or the lights on the side? Or the batteries? If it's the lights on the side, that's just a visual effect. You can change it in "Settings." If the batteries are flashing red, plug in your phone to charge!
It means there is a problem with the charging system. Can be a loose drive belt, problem with the alternator, or loose wire.
