You went to alot of trouble to fix a simple repair. We could have fixed your old one for $120. It's a common problem. The ignition switches are all the same. If you have EWS, the reader coil that fits over the barrel reads the chip in the key. The second hand ignition barrel & key wont work if you have EWS. You will have to refit the old one and we can still fix it for you. If you have the red infa red globe under your rear vision mirror, you have EWS and the second had parts wont work. If you have a solid key you cant get the chip out. You can only swap them on the remote type keys that have batteries in them. The chip sits next to the battery in the blade end of the key.

I had a similar problem and took my car to a garage and they have purchased a second hand barrel and key for $286 ad they charged me about $200 labour.
I need some more work done on my engine, how can I contact you?
