Tesla Hahn

I just had the rear main seal replaced and now I am having problems removing my key from the ignition. The van starts and runs great. When I turn the van off, the key will not come out. Honda told me to shift into drive then park again and try taking the key out. It works and the key comes out only to continue doing this each time I drive the van. I have another appointment at the Honda dealer however, could anything that was done to replace the main seal affect the key coming in and out of the ignition? This problem began after the main seal was replaced. I have not had any problems prior to this.
