Step 2: Mark the blank key for cutting
When you have successfully removed the door lock and readjusted the tumbler then you should take a blank key and insert it in the tumbler mechanism for marking purpose. When the blank key has been inserted, you should mark the positions of each tumbler with a pen or marker on the key blade. The portions that you mark would have to be cut to make the new key.
Step 3: Cut the marked blank key
When the blank key has been marked then you should create grooves of the key using a dremel tool with a cut off wheel. You can also use a jeweler’s file if you do not have the dremel tool. While you are cutting the key, or filing it, then you should check a few times whether the key is fitting or not. You must ensure that you do not cut the key below the marked lines. You must note that it is imperative to be patient while cutting the key because impatience might ruin your efforts.
Step 4: Test the new key
When you have completed cutting the new key, it is time to finally test the new key. The tumblers should be in perfectly flushed position with the outside plug of the tumblers. When the work is complete on your part then you should put the lock mechanism back in the door. If you have been successful in rekeying the car door lock then the new key would work perfectly. If you notice that the key is not working due to any reason then you would have to do the hard work again. You would have the repeat the process of rekeying a car door lock – remove the door lock and tumbler of the car, mark the blank key for cutting, cut the marked blank key and test the new key.

You would have to adjust the tumblers of the other door locks also so that the same key works in all the locks of the car.
