¿Dónde puedo copiar la llave?

Now that I officially (!) live in Spain, I reckon it's time to move beyond tourist Spanish. In places like Corralejo, ¿Dónde está el bar? or ¿Dónde está el restaurante? are really silly questions. They are, well, everywhere. ¿Dónde está la ferretería? — entirely different matter. I actually had to ask this last week. Although even that did not help: not every ferretería provides the service I was after.

¿Dónde puedo copiar la llave?

(For the record, I did not find any open establishment doing that in Corralejo.)

Here are a few more words which can be of real use when you just move in and start looking for stuff:

el cubo	bucket
el cuchillo	knife
la escoba	broom
el fontanero, la fontanera	plumber
la fregona / la mopa	mop
el hervidor	(electric) kettle
la lavadora / el lavarropas	washing machine
el lavavajillas	dishwasher
el (punto de) reciclaje	recycling (point)
el recogedor	dustpan
el sacacorchos	corkscrew
