I have a cisco asa 5505 firewall and the documentation given to us does not have a password that works. Is there a back door we can get into it??

The firewall is live and working. We just can't get into it and we need to run updates.

You'll need to do a password reset. reboot the firewall, "break" the bootup. You'll end up at a rommon> prompt where you'll enter the command confreg, and a list of options will be presented. Make sure to write down the current confreg code which is usually 0x0 or 0x1. The only option you need to take is to "ignore config at bootup". This will allow you to boot the asa without a config, get to privileged mode, copy the startup config to running. At this point the asa will be back up and running, and you'll be in privileged mode. Enter config mode, type in new passwords and you're good to go.
All that's left is to enter the command config-register 0x0 (or whatever the register was before you did the confreg command)
