Cerradura vs. candado vs. chapa
The Spanish words 'cerradura', 'candado', and 'chapa' all refer to different types of locks. While they share the primary function of securing an object or space, the main differences lie in their respective design and application.
Cerradura
The term 'cerradura' refers to a common door lock, which might be located on a front door, a room door, or a cabinet door. Generally, it implies the presence of a physical keyhole that works with a conventional key.

(I need to change the lock on my front door.)
La cerradura de mi habitación está atascada.
(The lock on my bedroom is jammed.)
Esta llave no encaja correctamente en la cerradura del armario.
(This key does not fit properly into the cabinet's lock.)
Candado
A 'candado' is a padlock, typically used for securing suitcases, lockers, gates or bicycles. Candados are portable and removable locks usually opened with a physical key or combination code.
Olvidé el código de mi candado y ahora no puedo abrir mi maleta.
(I forgot my padlock code and now I can't open my suitcase.)

(I'm going to put a padlock on the gate for extra security.)

(The padlock for my bike is very strong and rust-resistant.)
Chapa
'Chapa' can represent the functionality of a lock but often refers more specifically to the locking component generally found on doors, usually part of the door handle where you turn a knob or lever.

(The bathroom door's lock is broken and needs repair.)

Summary
'Cerradura', 'candado', and 'chapa' are three types of locks in Spanish with specific applications: 'cerradura' refers to regular door or drawer locks usually paired with keys; 'candado' defines portable and removable padlocks typically used for securing personal belongings or gates; and 'chapa' signifies the built-in locks typically found as part of door handles.
