Replacing a lost or damaged keyfob for your 2011 Mazda CX-9 can be a daunting task. However, with a little preparation and the right tools, you can program a new keyfob without the need for a dealership or locksmith. In this comprehensive guide, we’ll walk you through the step-by-step process of programming a new keyfob for your CX-9, ensuring that you have a convenient and reliable way to access and control your vehicle.
Before embarking on the programming process, it’s crucial to gather the necessary materials. You’ll need a working keyfob, a new uncut key that has been cut to match the ignition of your CX-9, and a Phillips head screwdriver. Additionally, ensure that your vehicle’s battery is in good condition, as a weak battery can interfere with the programming procedure. Once you have everything in order, you’re ready to begin the keyfob programming.
To start, insert the working keyfob into the ignition and turn the key to the “On” position. Do not start the engine. Within 10 seconds, press the “Unlock” button on the working keyfob three times. After pressing the “Unlock” button the third time, remove the key from the ignition. You should hear the door locks cycle, indicating that the vehicle is now in programming mode. Now, you’re ready to proceed to the next step of the programming process.
Inserting the Master Key
To insert the master key into the ignition, begin by locating the keyhole on the steering column. Ensure that the steering wheel is unlocked and in the neutral position. Grasp the master key and insert it into the keyhole. Turn the key clockwise until it reaches the “ON” position. The dashboard lights should illuminate, indicating that the key is properly inserted and the ignition is turned on.
Once the master key is inserted, you will need to complete the following steps to program the key fob:
- Press the “Unlock” button on the key fob once.
- Within 5 seconds, press the “Lock” button on the key fob twice.
- Within 15 seconds, insert the master key into the ignition and turn it to the “ON” position.
- Press and hold the “Lock” button on the key fob for at least 2 seconds.
- Release the “Lock” button and press it again.
- The key fob should now be programmed to the vehicle’s immobilizer system.
Additional Notes:
It is important to note that some Mazda CX-9 models may have slightly different key fob programming procedures. Refer to your vehicle’s owner’s manual for specific instructions.
If you encounter any difficulties during the programming process, contact your local Mazda dealership for assistance.
Turning the Ignition On
Step 1: Insert the Key Fob into the Ignition
Locate the ignition cylinder on the dashboard and carefully insert the key fob into the slot. Ensure that the key fob is properly seated in the slot.
Step 2: Turn the Key to the “ON” Position
Using the key fob, turn the ignition key to the “ON” position. This position is typically denoted by a green or blue LED indicator on the dashboard. Do not start the engine at this stage.
Step 3: Wait for the Security Indicator to Stop Flashing
After turning the key to the “ON” position, the security indicator light on the dashboard will start to flash. This indicates that the vehicle’s anti-theft system is active. Wait patiently for the security indicator light to stop flashing, which usually takes approximately 10-15 seconds.
Step 4: Remove the Key Fob
Once the security indicator light stops flashing, remove the key fob from the ignition cylinder. The key fob is now ready to be programmed.
