I purchased this vehicle at the end of July and it is like it was held together with spit and glue. This thing is falling apart! But first thing is first. I am replacing my ignition cylinder and tumblers. I bought an ignition cylinder/tumbler kit from the dealership. I know how to get my old cylinder out. What I am not sure of is how I know where to put the new tumblers in the new cylinder for my old key? Do I just take the old one apart and check the numbers on that or is there an easier way? Please help! My car is all sorts of taken apart in my driveway right now and I have to work tomorrow! Ugh!

If you got the key from the dealer did they program it? If not they will need to or the car wont start. Please give them the VIN. Here are some guides to help you get the job done (below). You must remove the plastic cover over the steering column first. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

Is it easy to change the tumbler in ignition. And if so how do I do it. I can take the key out when car is started and it sticks when trying to turn car on
