nothing works and I replaced the battery. to the fob
Make sure that you connected the battery cables properly. The red cable goes to the positive side(+) the negative or black cable to the (-) side.
Disconnect the negative terminal of the battery Leave it disconnected for an hour. (The amount of time it takes to replace the battery). Reconnect the negative terminal of the battery. This works because a transient (voltage spike, noise) is generated when the terminal is reconnected. This is not necessary when the battery is replaced because the negative terminal is normally the last connected. However, when a car's battery dies in storage for example and is recharged with disconnecting the battery, the car might not start because the computer is not running.
with a fully charged battery and clean connections to the starter and battery check fuses first and if good, replace ignition switch under steering column
Dead battery? Loose or corroded battery cable? Blown fusable link?
try replacing the alternator
it works in side the battery
Double check that the battery works, then check if the engine works.
how does a battery work
Make sure the mouse is plugged in and or/ has a working battery if it is wireless, if nothing works get a new one.
try checking all fuses in car and engine compartment
I have a vw polo 2000 that had ecu problems, so we disconnected the battery then the ecu from the car and left it for he day. The next morning we reconnected it and that reset it. hope it works for you too
