Most of the reviews were positive so I gave this lock a try. Many people who have bought have had error codes for gas seal leaks, which this lock can fix. I've never had this problem. I only bought it to protect my tank as I suspect someone drained fuel from my tank. I read a review that said it pops out easily with the dongle that came with it. Knowing this, I gave him the "key" test when he arrived. Of course, with minimal fuss, he emerged with the help of a key wedged between the tank and the lock. I returned it and bought a genuine Ford part and it's much more reliable and I couldn't put the key in between. As a visual deterrent or filling aid, this is a good way, but not the best way, to seal off the aquarium.
