Trying to figure this out for my 2003 MAZDA Protege too!

I’ve got a 2012 2003 MAZDA Protege, would this method still work?

I have a 2011 2003 MAZDA Protege, will this method work for that year?

🔑 Car Key & Fob FAQ

Common questions about key programming, fob issues, and replacement options

Lost Keys
Dealerships can often cut keys using your VIN, but will require proof of ownership. This only works for original factory keys - aftermarket or previously replaced locks won't match. The key will still need programming to start the car if it has a transponder.
Key Tip: Always have at least two working keys to avoid expensive replacements
Lost Keys
Yes, a skilled auto locksmith can extract the broken key and make a replacement. They can often do this without damaging the ignition cylinder. The new key will need programming if it has a transponder chip.
Key Tip: Some locksmiths offer mobile key programming services
Key Programming
Most transponder keys and smart keys can be reprogrammed if they haven't been damaged. Basic mechanical-only keys (no chip) can't be reprogrammed - they must be physically cut to match your locks.
Key Programming
Most transponder keys and smart keys can be reprogrammed if they haven't been damaged. Basic mechanical-only keys (no chip) can't be reprogrammed - they must be physically cut to match your locks.
Key Tip: Replace key fob batteries every 1-2 years as preventative maintenance
Cost & Options
Quality aftermarket keys work well for most vehicles at lower cost. However, some luxury brands use proprietary technology only available through dealers. For expensive cars, OEM may be worth the extra cost for reliability.
Key Tip: Newer cars often require dealer programming for first key replacement
Key Fact: Modern transponder keys have been required in all new US vehicles since 1998
