Reinforced or locking gas tank lid?

[magarity]

I got half a tank of gas siphoned out of my Legacy by a thief while I was in the grocery store yesterday. They pried open the lid and bent it. Does anyone know a good reinforced or locking tank cover that would deter a thief to target someone else?

I hate these things, but they come and go in popularity. They seem to work fine, but are a bit of a pain. Times change.https://www.amazon.com/Locking-Outb...Subaru+Outback+gas+cap&qid=1647989859&sr=8-10
