Cadillac keys — what you should know
Cadillac uses GM key architecture and we cover the range on site including proximity keys. The Escalade is a frequently targeted vehicle in the GTA, and as with other proximity-key vehicles, relay attacks and diagnostic-port programming are the methods that matter — a signal-blocking pouch and an OBD port lock address both.

A model not listed is not a problem — give us the year and we will confirm before dispatching.
Cadillac keys — questions
Can you make a Cadillac key if I have lost all of them?
For most Cadillac models and years, yes, and at the vehicle rather than at a dealership. B111/B119, shared across GM — we cut from code obtained through authorised channels or by decoding the lock directly, then program to the immobiliser on site. GM proximity systems across the current range. We verify ownership before any of it, every time.
What kind of key does a Cadillac use?
B111/B119, shared across GM. GM proximity systems across the current range. This matters because cutting alone is never enough on a modern vehicle — a key cut without programming works the lock and turns the ignition, and the engine cranks and does not start. Give us the year and model and we will tell you exactly which key your car takes before coming out.
How much is a Cadillac key, and how long does it take?
Price follows the key type, not the badge — a transponder key is at the low end, a remote head key in the middle, a proximity smart key at the top because the blank itself is expensive. A spare with a working key present is usually thirty to sixty minutes on site. All-keys-lost takes longer, and several makes impose a manufacturer security wait of ten to sixty minutes during programming that nothing can shorten.
