2010 Lincoln MKS Key Fob Programming: Your Comprehensive Guide

Losing or needing a spare key fob for your 2010 Lincoln MKS can be a common inconvenience. Fortunately, programming a new key fob yourself is possible under certain conditions, saving you time and money. This guide provides step-by-step instructions for programming both Remote Head Keys and Intelligent Access Keys for your 2010 Lincoln MKS.

Programming a Spare Remote Head Key for Your 2010 Lincoln MKS

This method is applicable if you have two already programmed keys. If you only have one or no programmed keys, you will require the services of a qualified locksmith to program a new key for your Lincoln MKS.

Step-by-Step Programming Instructions:

1. Insert First Programmed Key: Begin by inserting your first, already working programmed key into the ignition of your 2010 Lincoln MKS.

2. Turn Ignition On: Switch the ignition from the “off” position to the “on” position. Ensure you keep the ignition in the “on” position for a minimum of three seconds, but do not exceed ten seconds.

3. Turn Ignition Off and Remove Key: Switch the ignition back to the “off” position and remove the first programmed key from the ignition.

4. Insert Second Programmed Key: Within three seconds, but no later than ten seconds after switching the ignition off, insert your second, already working programmed key into the ignition.

5. Turn Ignition On Again: Switch the ignition from the “off” position to the “on” position once more with the second key. Again, keep the ignition in the “on” position for at least three seconds, but no more than ten seconds.

6. Turn Ignition Off and Remove Key: Switch the ignition off and remove the second programmed key from the ignition.

7. Insert New Unprogrammed Key: After three seconds, and within ten seconds of switching off the ignition and removing the second programmed key, insert the new, unprogrammed key into the ignition.

8. Turn Ignition On and Wait: Switch the ignition from the “off” position to the “on” position. Keep the ignition in the “on” position for at least six seconds this time.

9. Remove New Key and Test: Remove the newly programmed key from the ignition. To verify successful programming, attempt to start your 2010 Lincoln MKS with the new key. Also, test the remote entry system functions (lock, unlock, panic) if your new key is an integrated keyhead transmitter.

If the vehicle starts and the remote functions operate correctly, the key has been successfully programmed. If programming is unsuccessful, wait ten seconds and carefully repeat steps 1 through 8. If issues persist, it is recommended to consult a locksmith or dealership.

Programming a Spare Intelligent Access Key for Your 2010 Lincoln MKS

This procedure is for programming Intelligent Access Keys, often referred to as smart keys or proximity keys. For this method, you will need to have two previously programmed Intelligent Access Keys already inside your 2010 Lincoln MKS. If you do not have two existing Intelligent Access Keys, a locksmith will be required to program additional keys.

Important Notes Before You Begin:

• Maximum Keys: A maximum of four Intelligent Access Keys can be programmed to your Lincoln MKS.
• Replacing Keys: If you wish to replace a lost or non-functioning Intelligent Access Key, or if you already have four programmed keys, a locksmith must erase existing programmed keys before new ones can be added.
• Vehicle State: Ensure your 2010 Lincoln MKS is turned off and all doors are fully closed before starting this procedure. Keep all doors closed throughout the entire programming process.
• Timing is Crucial: Perform each step precisely as described and within 30 seconds of starting the sequence. If any step is performed incorrectly or out of sequence, stop, wait for at least one minute, and then begin again from step 1. It is highly recommended to read and fully understand all steps before you commence the programming.

Step-by-Step Programming Instructions:

1. Place New Key in Glove Box Pocket: Locate the designated pocket inside your glove box and place the new, unprogrammed Intelligent Access Key into this pocket.

2. Press Unlock Button Three Times: Press the power door unlock control (either on the driver’s or passenger’s side door) three times.

3. Press and Release Brake Pedal: Press and release the brake pedal one time.

4. Press Lock Button Three Times: Press the power door lock control (either on the driver’s or passenger’s side door) three times.

5. Press and Release Brake Pedal Again: Press and release the brake pedal one time again. At this point, observe the indicator light on the Start/Stop button of your Lincoln MKS. It should begin to flash rapidly. This flashing indicates that the programming mode has been successfully entered and that the system has detected the presence of two programmed Intelligent Access Keys inside the vehicle.

6. Press Start/Stop Button: Within one minute of the indicator light flashing, press the Start/Stop button. Observe the message center display in your instrument cluster. If the new Intelligent Access Key is programmed successfully, a message confirming this should appear. If you already have the maximum of four Intelligent Access Keys programmed, a message “MAX # OF FOBS LEARNED” will be displayed, and you will not be able to program any additional keys without erasing existing ones.

7. Remove Key and Exit Programming Mode: Remove the newly programmed Intelligent Access Key from the glove box pocket. Press the unlock or lock button on the newly programmed key fob to exit the programming mode.

8. Verify Functionality: Test the remote entry functions (lock, unlock) on the new Intelligent Access Key. Then, attempt to start your 2010 Lincoln MKS using the new key. If the key has been programmed correctly, it will activate the Intelligent Access with Push Button Start feature and start your vehicle.

By following these instructions carefully, you should be able to program a new key fob for your 2010 Lincoln MKS. However, if you encounter difficulties or lack the necessary existing keys, remember that professional locksmiths specializing in automotive key programming are readily available to assist you. They possess the specialized tools and expertise to handle various key programming needs, ensuring you can get back on the road quickly and securely.
