Step-by-Step Procedure:

Plug the IM508S tablet into the vehicle’s OBD port.

On the tablet:

• IMMO >> Accept >> Ford >> Manual Selection

• Select Yes when prompted for Smart Key
• Navigate to ECU >> Parameter Reset [Fuel] >> Parameter – Reset

3.Turn on the Ignition

4.Autel IM508S Warning
You will receive a warning:
“Perform this procedure only if you have replaced the PCM or PATS on this vehicle.”

• Press YES or NO

5.Parameter Reset Process

• The system will read data, please wait.
• The instrument panel might go black during this function—this is normal.
• After security access is granted (this takes 3-10 minutes), you’ll see a Learning Successful message.

6.Program New Keys
Navigate to:

• Control Unit >> Keyless System “CAN” >> Learning Keys >> All Smart Keys Lost

Important Notes:

• A network connection is required, so ensure the device is connected via WiFi.
• Again, it’s normal for the instrument panel to turn black during this function.
• This process will delete all previously learned smart keys.

7.Continue with Key Programming

• Press OK to proceed.
• If asked whether the alarm is active, select No.

8.System Configuration

The system will configure, taking approximately 10 minutes.

• Select Yes if you want to delete all keys (you will need to program two keys afterward).
• Select No if you just want to add keys without deleting the existing ones.

9.Delete and Program New Keys
If you choose to delete all keys:

• The system will confirm Current number of keys: 0 after deletion.
• Insert the first smart key into the designated slot (in the armrest compartment, cupholder, or glovebox).
• The system will begin learning the key.

After the first key is learned:

• The system will show Current number of keys: 1.
• Remove the first key and insert the second smart key into the slot.
• The system will learn the second key.
• After learning is complete, the display will show Current number of keys: 2.

Finish Key Programming

• Press NO to finish the process after learning both keys.

 

Test the Keys

• Both keys should now work correctly.
