Would this kit be ok to replace the original ignition switch and
Door latch? My keys are too loose in the ignition switch and it is too difficult to get the key in/out of the switch. They currently
Don't open the door latch from the outside. The seller also will program the keys.

I'm not that handy so I'd be taking this to my mechanic....Just wondering if there are other miscellaneous parts I would need or if this is it?

The seller cannot program the keys as they have to be programmed in your car with a computer connected with your BECM.

So yes, this will work with your car, but the remote will not unlock your doors as you have to have it programmed to your car.

Its really easy to install. I could walk you through the process if you want.
