Acura keys — what you should know
Acura shares Honda's key architecture, so coverage matches the equivalent Honda models including proximity smart keys. The MDX and RDX are frequently targeted in the GTA through relay attacks on the proximity key, and a signal-blocking pouch is a cheap and effective precaution.

Acura keys — questions
Can you make a Acura key if I have lost all of them?
For most Acura models and years, yes, and at the vehicle rather than at a dealership. HON66, shared with Honda — we cut from code obtained through authorised channels or by decoding the lock directly, then program to the immobiliser on site. Honda immobiliser architecture; proximity across most of the current range. We verify ownership before any of it, every time.
What kind of key does a Acura use?
HON66, shared with Honda. Honda immobiliser architecture; proximity across most of 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 Acura 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 made while you still have a working key is the quicker job. All-keys-lost takes longer, and several makes impose a manufacturer security wait of ten to sixty minutes during programming that nothing can shorten.
