How is a relay like an electric lever?
You can think of a relay as a kind of electric lever: switch it on with a tiny current and it switches on (“leverages”) another appliance using a much bigger current. As the name suggests, many relays are incredibly sensitive pieces of electronic equipment and produce only small electric currents.
What makes up the heart of a relay?
The heart of a relay is an electromagnet (a coil of wire that becomes a temporary magnet when electricity flows through it). You can think of a relay as a kind of electric lever: switch it on with a tiny current and it switches on (“leverages”) another appliance using a much bigger current.
Where is the relay on a door lock?

What happens if my door lock relay fails?
Commonly the computer will override the relay circuit when using a keyless remote access to the locks, routing the power through the alarm system provided that the vehicle is equipped with an alarm of some sort. A key can still manually unlock the doors. Some computer codes that may be displayed for a failed door lock relay include:
