2003 Mazda MPV ESFACTORY OEM SERVICE PROCEDURE

To Erase Additional Keys Using Only Two Programmed Keys

WARNING: This page is about a different car, the 2003 Mazda Tribute. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
  • With two programmed keys, it is possible to erase the codes for all OTHER additional keys to make them unusable (i.e. after they have been lost).

Erasure procedure:

  1. Follow steps 1-4 as described above.
  2. After second key, insert the first key AGAIN and switch ignition to ON.
  3. The security light will flash rapidly for five seconds.
  4. All key codes BUT the two keys used in this procedure have been erased and will not start the vehicle.
    NOTE:
    • If the ignition is switched OFF before the five second period (described in step three) has completed, the erasure procedure is cancelled and NO key codes are erased.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
