“The first time I ordered the replacement key it would not let me put in the alpha in front of the number. I had to jump through hoops with 'need picture of this', then 'need picture of this', then 'need a picture of the replacement and original key'. Well, like I explained 3 times, the key is locked in the drawer (another key locked it but will not open it). Then, no response, no replacement key, nothing. I hope this order goes more smoothly. ”
