Step-by-Step Programming Guide for 2001 Impala Key Fobs
Follow these instructions carefully to program your 2001 Chevy Impala key fob:
-
Locate the Programming Connector:
- For Sedans: Access the trunk and locate the programming connector. It’s a two-pin connector located on the left side of the rear compartment, often hanging loose and not connected to anything.
- For Wagons: Remove the right back body pillar finish panel to find the programming connector.
-
Ground the Programming Connector:
- Connect the two terminals of the programming connector together to ground it.
- Verification: The system will automatically respond by performing a lock all doors, unlock driver’s door/unlock all doors, and then cycle the trunk/endgate lock. This confirms you’ve successfully grounded the connector and entered programming mode.
-
Program the First Transmitter:
- Press any button on the key fob you want to program.
- Verification: The system will again perform the lock all, unlock driver’s door/unlock all doors, and trunk/endgate cycle to confirm successful programming of this transmitter.
-
Optional: Disable Automatic Door Locking/Unlocking (Per Transmitter):
- If you wish to disable the automatic door locking/unlocking feature for this specific transmitter, perform the following sequence three times immediately after step 3’s verification cycle:
a. Press the Door Lock button within 1 second.
b. Press the Door Unlock button within 1 second of step a.
c. Press the Trunk button within 1 second of step b. - Verification: The receiver will cycle through the lock, unlock, trunk sequence three times to confirm the automatic door lock/unlock function is disabled for this transmitter. If you want to keep the automatic function enabled, skip this step.
- If you wish to disable the automatic door locking/unlocking feature for this specific transmitter, perform the following sequence three times immediately after step 3’s verification cycle:
-
Program a Second Transmitter (If Needed):
- If you have another key fob to program, repeat step 3 with the second transmitter.
-
Disconnect the Programming Connector:
- Crucially, disconnect the terminals of the programming connector from each other. Important: The keyless entry system will not operate if this ground connection remains in place.
-
Verify Operation:
- Test each programmed transmitter to ensure they correctly lock and unlock the doors and operate the trunk/endgate release.
-
Reassemble Trim:
- For Sedans: Reposition the rear compartment trim in the trunk.
- For Wagons: Reinstall the right back body pillar finish panel.
Congratulations! You have successfully programmed your 2001 Chevy Impala key fob. Always verify that each transmitter is working as expected after programming.
