Query: Failure of locking mechanism

I bought these and the first time it rained, the locking mechanism on one popped up. I snapped it back down when I got home and then the next time it rained, it happened again. So I bought a spool of stainless steel wire ($8.00) and melted a pin-sized hole all the way through the plastic of the locking mechanism and ran the wire through it, bending down both sides. Seems like a lot of work and cost. I would have returned them but the store wasn't near.
