Review on 🔒 Enhanced Security: ACDelco Professional 12F20LA Locking Fuel Tank Caps Keyed Alike (Pack of 2) by Doug Davis

Didn't know there were two covers and two sets of keys in the box. I thought "double lock" was a term for some type of lock. It fits easily in my 1995 Ford Escort. Before putting the cap on, make sure the key is in the lock and turned to the left (not straight), then twist/turn the cap to the right until you hear a click (no more than a click because it is like I broke the old one, too many clicks can break the spring). Turn the key to the right to lock it and you're done. I will update if there are problems.
