Mazda Protege key types & programming facts
The 2000–2003 Mazda Protege uses a traditional metal ignition key plus a separate keyless entry remote fob on vehicles equipped with remote entry. For models with immobilizer, replacement keys typically require cutting and transponder programming to the vehicle, while remotes are paired via an onboard procedure using the vehicle’s ignition and door locks. Programming usually needs all existing remotes present so they continue to operate after the procedure.
Key types used on the Protege:
- transponder chip key (separate metal key with integrated immobilizer chip) (2001-2003 (transponder keys sold for Protege; earlier years may be non‑chip but sources do not clearly specify))
Common fob FCC IDs: KPU41015, KPU41704 — check the back of your fob; we confirm the exact variant on site.

How we validate this guide
Year coverage comes from our consolidated vehicle programming dataset. Route-level programming status is reviewed against internal route sheets and available manufacturer, security-access, and professional tool references. Exact button sequences are marked source-verified only when we have year/equipment-specific support; where a year is labeled “route verified, steps vary,” we confirm the exact fob, trim, and prompts before programming.

Common questions
Does my 2000–2003 Mazda Protege use a transponder chip key?
Many replacement services list transponder keys for Protege models of this era, but not all trims used an immobilizer. A locksmith or dealer can check your VIN to confirm.
What remote fob do I need for my Mazda Protege?
1998–2000 Protege models commonly use a 4‑button remote with FCC ID KPU41015, while 2001–2003 Protege and Protege5 typically use a 3‑button remote with FCC ID KPU41704.
Can I program a replacement remote for my Protege myself?
Yes, many 2000–2003 Protege keyless entry remotes can be programmed with an onboard procedure using the ignition and door locks, without special diagnostic tools.
Can you program a Protege key fob without going to the dealership?
For most years, yes - the route is onboard relearn or an OBD tool, both of which a mobile locksmith handles at your location.
Does this program the remote only, or the transponder key too?
It depends on your key type. Tell us your FCC ID and we will confirm.
What if my year says professional programming required?
Those years need a programmer or security access; we bring the tool to you and program it on site.
How much does it cost?
It depends on year, key type, and whether you have a working key. Call (833) 439-8636 for a firm price before we dispatch.
