When flat buzzer is pressed , buzzer rings in flat , we lift handset , switch on base unit extends . We can hear person outside speak but they are unable to hear us . We then de-press button on base unit for them to enter. They can hear a buzz at door but lock does not disengage and are unable to enter. Any ideas what could b the problem. Handset and base unit where knocked off the wall. Souldered connection onto privacy switch had came off. I resouldered wire and was then able to hear person outside speak . Thought I had cracked it but unfortunately lock still not coming off. Cheers john
