Definitely in the category of First World Problems... BUT, I've always found the area around the ignition lock to be a bit tight when putting the standard key in the ignition (of my RHD car). A quick look on eBay found a key blank which is 15mm shorter.
Sometimes it's the little things that make a difference!

For reference, the standard key is 73mm long and the new one is 58mm.
