House & Car Key Types Explained

Not all keys are the same. Here is a quick, honest rundown of the common types so you know what you have and what a copy involves.

House keys

Most homes use standard pin-tumbler keys that any locksmith can copy quickly. Some higher-security locks use restricted or patented keys that need proof of ownership and a specific blank to duplicate.

Car keys and fobs

Many modern car keys contain a transponder chip that must be programmed to the vehicle, and push-to-start cars use proximity fobs. These take the right equipment and the vehicle details — not just a blank cut.
