My pin screen comes on but wont take my pin

What is it doing/saying exactly? If it is saying nothing or not recognizing that you are touching it, then you need to get it looked at by either the manufacturer or a local tech.

However, if it is saying it is the wrong PIN, then we cannot assist with that. You will have to remember the correct PIN. Please read the following thread... http://www.tomsguide.com/forum/id-2317976/read-passwords-lock-codes-pin-numbers.html
