Additional Keys

I bought the slider Handle/Lock Dec 13 2019 with two keys, pictured. I installed as a replacement on my patio slider door. Had difficulty getting key copies on 'new' key copiers in Home Depot. Finally used the 'old' key copier with success. HOWEVER, the only key blanks have a square head, which hits my slider frame, making it difficult and near impossible to lock and unlock.

No one has a key blank such as yours (pictured) which works well in my door.

Can I have three or four more key blanks as shown in the picture? I can get copies if I have your style key.
Thanks
