If you have electric locks, the battery is what actually does the 'unlocking'. If the battery is dead, it obviously won't work. Many locks have a supplementary mechanical linkage to allow unlocking by turning the key in the door lock, but sometimes that mechanism is broken. Try unlocking the passenger side, as a backup plan.
Dead battery ?
Yes.
My battery start going weak and went completely dead, now I excange batteries and the car went to a security mode and wont start back, as soon as I open the doors the hazard lights go on and the car wont start, is any procedure to be done thanks Juan
you can but it wont stay running if the battery is dead
Dead battery, disconnected starter cable, or the engine is missing.
Do your headlights work or if you open the drivers door with the keys in the ignition do you hear a warning buzzer or chime . If not , it sounds like a poor battery connection or a dead battery
no the car wont start because the battery is dead, it was discharged by running it and not being recarged by the alt
that means your battery will be dead in the morning
That could be the alternator or the battery. Try jump starting your car with another car's battery. If it still does not start, it is probably the alternator. If it starts, your battery is dead.
You ran the battery dead. Jump the car and let it stay running for a while so it can recharge itself
use the key open the car open the hood and jump charge the battery other than that phone a main dealer
with the key... or a slim Jim Key is not working at the door
