Hello,

First off need to know if it is the Car or the Van. And you are trying to replace the Lock Cylinder and Key not the Ignition Switch. Sorry to ask but some people aren't quite sure what to call it and some places call it different things also.

Thanks

Hello,

My suggestion would to have the Lock Cylinder replaced it will come with a new set of keys for the Ignition. They will not work on the Doors. You can call a Lock Smith and see if they can make you a new key for the doors and ask if they can Rekey it. Meaning that if whoever stole your keys will not be able to use them to gain access to your vehicle.

I've had this problem a few times. Sometimes you can get lucky and just clean the lock. Spray some dust off computer cleaner in there, or lock deicer if you have any, followed by some WD-40. It may take a lot of in and outs of the key and turning to free up what is caught in there. Also try the spare key. Sometimes the lock is good but the key wears out, also though sometimes the lock and key wear out together so the spare key is worse. You should be able to buy the lock assembly online for cheap, but you have to take apart the column in order to put it in. If you do have to replace the lock, make sure your key doesn't have the anti-theft chip in the key. If it does, you may need to either buy a factory lock, or stash the old ket in the column next to the lock so it thinks you're using the original key.
