Using the Keyless Entry Keypad (If Equipped)

WARNING: This page is about a different car, the 2007 Mercury Mariner and 2007 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: A manual enable/disable mode allows the autolock feature to be turned off and on.
  1. Enter the 5-digit permanent entry code into the keyless entry keypad.
  2. Within 5 seconds of entering the code, press and hold the 7/8 button on the keypad.
  3. Within 5 seconds of Step 2, and while holding the 7/8 button, press the 3/4 button on the keypad and release it.
    4. NOTE: If the autolock is disabled, the horn chirps once. If the autolock feature is enabled, the horn chirps once shortly and then sounds a second time for a longer sound of the horn once the above sequence is completed.
  4. Within 5 seconds of Step 3, release the 7/8 button on the keypad.
