Key wont turn to start car

Do you mean that after you removed the wrong key your original key wont go in, or do you mean using your original key and turning the starter it wont start or even turn the ignition on. If you tried to turn the ignition switch with the wrong key, sometime it will cause the lock to turn freely as an anti theft measure. You should be able to find the way to fix this in the user manual that comes with the car.

Check the fuse box for the starter relay, and pull out to check pins for corrosion / bad contact. The fact it start on a bump with the key on leads me to suspect the start / crank position of the electrics. Get a knowledgeable person to run through the crank circuit with a meter, also check the condition of earth straps and starter cables. Could be the ignition switch is faulty?

it wont start you mean it dosnt turn over no battery left or it cranks but no start clean all the keys and you should have a master key like a green one or blue with a m on it put this key in the ignition turn on the ignition without starting then turn it off and repeat with the other keys you have as well make sure its in the park position and start it after you have finish with all the keys if wont crank over try in neutral position no start fuses battery starter and so on to check after

Change ignition barrel or get a new key cut try spraying lubricating oil down the barrel

try another key. the key could be worn where read coil in the ignition switch lock cylinder and immobilizer control module and ecm dont recognize ignition key or ignition switch key lock cylinder failing.

Your car uses a transonder key, a key with a small chip embedded inside. The transponder is matched to the immobilizer unit in your car. When the key is inserted into the ignition, the immobilizer searches for that transponder, if it's not near the ignition, the car will just keep turning over and not start. Your only real options are to replace the steering lock or buy a transponder bypass unit, which I do not recommend. Just do a google search.

try wiggling key around rapidly and up and down while trying to turn on
key and ignition barrel are worn and need replacing

is it correct key? key and ignition barrel could be worn wiggle key around in ignition while turning? gently but fast wiggling.try lube in key slot also.
if not replace barrel and key

try checking the main relay under the dash

Do you have a Chip in the Key? if so that Could be the Problem,Ya see the chip is a resistor and if it looses its ELECTRONIC VALUE in its Case Resistance it wont start to test this Turn the Key in the ON posission then do the Screwdriver thing If it Starts Key is Good and Most Likely the Ignition (SWITCH) is Bad <<ELECTRICAL Side NOY LOCKEST SIDE For More Info Recontact Me
