Autel IM508S – PCM Parameter Reset and Programming All Lost Keys for 2018 Ford F150

Today, we’ll show you how to use the Autel MaxiIM IM508S to perform a PCM parameter reset and program keys on a 2018 Ford F150 after all keys have been lost. You will need two new smart keys for this process.

Step-by-Step Procedure:

1. Connect the IM508S
   Plug the IM508S tablet into the vehicle’s OBD port.
2. Access the IMMO System
   On the tablet:
   • IMMO >> Accept >> Ford >> Manual Selection
   • Ford >> USA >> F-150 >> 2018-2020 >> Smart Key
   • 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 to continue.
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.
10. Finish Key Programming
    • Press NO to finish the process after learning both keys.
11. Test the Keys
    • Both keys should now work correctly.

Completed!
