problem unlocking my nokia 2100

I´ve downloaded the nokia free unlock codes calculator 3.10, entered my imei number (351344557904965), my country (Brazil), my cell phone operator (Tim) and the program gave me this:

#pw+187 300 371 7+1#

So, I used number 1 in the blank spaces (as said in the help button). I took off the sim card, and start to enter the code, BUT i couldn´t enter the last character, the "#"; I pressed the button but the phone wouldn´t write it in screen and the phone was not locked up.

Is there someone who can help me? thanks in advance.

Type the whole code with no spaces.

appeared "the phone wasn´t registered". so it worked?
