My car battery was low (won't start) so I was jump started the battery with my other car. However I was jumped start it incorrectly. The jump start cable was melted and the battery in my ford is completely dead. The keyless won't work. How bad is the damage to the car?

Thank you,

    Does anything electrical work? It could just mean resetting the security system.

    No, it does not work at all. Can I reset the security system myself? Thank you.

    If the old battery had any charge at all left then you didn't apply reverse voltage to the car's electrical system. But the cells in that old battery are now likely welded together so only a new fresh battery in its place is likely to even have a chance of working

    Hi Wwest,

    I called triple A to get a new battery. The mechanic tried to jump start it first to run test before he replaced the battery. It was working but like you said, the battery welded so it's need to be replaced. The battery has been replaced and the mechanic run the test, it's working good and there is no electrical damage to the car. Thank you for your kind assistance, I really appreciate it.

    Best Regards,
