My Verifone Vx 520 has a locked key pad.
Most likely cause:
Someone will hold down the eight button locking the terminal keyboard, and then the credit card terminal requires a password.
How do I unlock my VX520 keyboard, if I lock it?
Steps to Unlock the Vx 520:
- Push the eight button again
- Enter the password, which is one, alpha, alpha, six, six, eight, three, one, and enter.
- Select ‘no’ to unlock. That will unlock the keyboard, and processing transactions can continue.
