Just because it is no fun sitting in a parking lot for an hour trying to get the thing unlocked. NOTHING I do with mine makes it work right, and I have tried all the recommendations, plus some I thought up. After forever I get it to unlock. Next time? Who knows? Life is just too short to mess with it.
It appears from the threads over the years that they either work easily or they are a bear to unlock. If yours works fine, great. If not, forget it.

PS: Mark, you are a PATIENT man. I can't imagine working two years on that sucker! :-D
