Punjab National Bank [PNB] — Transaction password

Address:

110092

My transaction password has been disabled. How can i activate my transaction password without visiting the bank? I am outside delhi. I request to activate my transaction password. Please send the transactions password to my registered email or my mobile phone. Please do the same as quick as possible.
Due to error in the network my password was deactivated about 3 months ago. As i am outside delhi i am unable to visit the branch. My account is open in mangal market branch, laxminagar.
Please solve the problem as early as possible. Thanking you in advance for your cooperation.
