Forum:Problems opening locked containers

Just started playing ME1 and I'm only having one problem. The mini-game for opening locked terminals and containers is proving to be impossible. I have no problem with the resource gathering mini-game on planets and I have nimble fingers (never have a problem in other games following these types of "Simon says" codes). I've just about maxed out my Techs decryption and (I forget the name of the other one) skills, and I'm only 10th level. I'm having to break everything down for the omni-gel and it's a real pain. I'm playing on an Xbox 360, is it a glitch? Is there anyway to desensitize/slow it? Does it get easier? Is there an omni-tool I can buy/find somewhere that bypasses them? Please help, it's starting to make the game suck. :(
