Hi everyone,

I have a 2016 CX-5, and just lost one of our 2 keys that came with the car. It just so happens that my uncle has a Mazda smart key from a car that he sold laying around.

The actual key itself obviously won't be able to open my door, but I was wondering if there's a way me or the dealer can "re-program" this key so that it can turn on my engine. Best if there's a way to do this myself, but either way, it certainly beats paying the dealership $300 to buy and program a new key...

What Mazda did your uncle have?

To answer your question if you can do it yourself, the answer is no.

The key fob itself is usually pretty cheap anyways. Where the dealership get you is labour for reprogramming the key fob via obd. It only takes a few minutes yet they charge a few hundred.

Nope.

The dealer might but will probably say no. They want to sell you a new one.

If you do manage to get it reprogrammed, you should should be able to order just the metal part that you can get cut so it can open your doors too.
