Don’t say ‘the key of’ something. Say the key to something

اگر بخواهیم مفاهیمی از قبیل کلید خانه/ کلید ماشین/ کلید در/ کلید کمد و کلید ..را بیان کنیم.

معمولا از ساختار key to استفاده می کنیم نه از ساختار key of .

This is the key to the apartment

This is the key of the apertment (it is wrong)

I need the key to the front door

I can lend you a spare key to the store until you get one cut

I’d like a key to room 809, please

There were two keys to the cupboard

Please give me the keys to the car/ door

But

car keys / door keys
