Mazda Key Fob Replacement

Mazda builds cars for people who like driving, from the MX-5 Miata to the family CX SUVs, and keys get lost across all of them. We carry OEM-quality Mazda key fobs, smart keys, and remotes for the Mazda3, CX-5, CX-9, Miata, CX-30, and more, for a fraction of the $215 to $445 a dealer charges. Every key ships fast from the US and is covered by a 30-day return. Match the FCC ID on your current key, or use the year-make-model search up top.

Frequently Asked Questions

Does my Mazda3 or CX-5 use a smart key?

Most recent ones do, with push-button start and the Advanced Keyless proximity fob. Base and older models often use a flip key. The FCC ID on your current key, listed on every product, tells you which fits.

Does the Miata use the same key as the rest of the lineup?

The MX-5 uses Mazda's system like the others, but its fob and FCC ID are specific to the model and year, so don't borrow a Mazda3 key spec for it. Match the numbers on your own key.

How much is a Mazda key at the dealer?

Usually $215 to $445 programmed, with the smart keys at the higher end. Ours come in well below that.

What battery does a Mazda fob take?

Most use a CR2032 coin cell, swappable in a minute. A weak battery is the common reason for short range, so try a fresh one before replacing the fob.

Do you have keys for older Mazdas like the Mazda6 and CX-7?

We do, alongside the current cars. Older Mazdas often use a transponder or flip key rather than a smart fob, so match your year and FCC ID.
