Mazda Add a Key With Two Working Keys
Updated 2026 68 vehicles 2003–2015
This procedure covers 68 Mazda vehicles from 2003 to 2015. Check that yours is listed below, then follow the steps.
Need the fob itself?
Pick your vehicle to see replacement fobs on Amazon. Match the FCC ID on your old fob before you buy.
Not sure which fob is yours? Find your year below for the exact FCC ID and part number.
You can add a new key to this Mazda yourself if you already have two keys that start the engine. The new key must be cut first, and it has to be a genuine key — a cloned hardware-store key won't work.
Before you start
- Two original keys that already start the engine
- Your new key, already cut
- 1Insert one working key and turn it to ON (just shy of starting). Hold it there about 3 seconds, until the security light goes out.
- 2Turn back to OFF and remove the key.
- 3Within 10 seconds, insert the second working key and turn to ON. Again wait about 3 seconds until the security light goes out, then turn OFF and remove it.
- 4Within 20 seconds, insert the new key and turn to ON. Hold for at least 3 seconds, then turn back to OFF.
- 5The security light comes on for three seconds — that confirms the new key is programmed.
Tips & troubleshooting
- No two working keys? These keys can't be cloned at a hardware store (Ace, Lowe's, Walmart, Home Depot). You'll need an automotive locksmith or dealer.
Which fob does your vehicle take?
These steps program a fob to your car — they can't tell you which fob to buy, and one that isn't the right part for your vehicle will not pair no matter how carefully you follow them. Find your vehicle below: tap your year for the exact fob it takes — FCC ID, OE part number and battery — or "Shop fobs" to browse replacements for that model.
