What to do if Philips Home Access 4000 only locks but does not unlock?

If your Philips Door locks only locks but does not unlock, or the Latch Bolt goes in and out uncontrollably, it might be due to a problem with the door frame. Ensure the hole in the door frame is drilled a minimum of 1"(25mm) deep to provide enough space for the deadbolt. It can also be because of the lock handing or installation. Restore the lock to the factory default setting. If that doesn't work, re-install the lock and reset it again. If the issue persists, further assistance may be needed.
