英国采购需求：钥匙管理、电子钥匙柜、钥匙管理系统、钥匙控制系统、智能钥匙柜、钥匙管理柜

I'm looking to expand our product line and am interested in importing small key boxes designed specifically for residential use. I'm targeting a model that can securely hold no more than six sets of keys. Ideally, it should feature a phone app that allows users to access the key box remotely, as well as a backup key entry option for added security. Additionally, I'm envisioning a design that offers a discreet appearance, such as being concealed behind a mirror or painting, blending seamlessly into home decor. If your factory produces similar products or can tailor items to meet these specifications, I would love to explore potential collaboration opportunities.
