How to Program a Chevrolet Impala Key Fob
If your Chevrolet Impala key fob is unresponsive or only works intermittently after troubleshooting, reprogramming it might be the solution. Here’s a general guide to programming your key fob. Note that these steps may vary slightly depending on the year and model of your Chevrolet Impala:
Programming a New Key Fob:
- Gather Your Materials: You will need all existing working key fobs and the new unprogrammed key fob.
- Enter Programming Mode: Sit in the driver’s seat with the doors closed and windows up. Insert the working key fob into the ignition and turn it to the “ON” position. Then, rapidly turn the key between the “OFF” and “ON” positions several times (usually four to eight times) ending in the “ON” position. The vehicle’s hazard lights will flash, indicating you’ve entered programming mode.
- Program the New Key Fob: Press and hold the “LOCK” and “UNLOCK” buttons on the new key fob simultaneously for 15 seconds or until the vehicle’s hazard lights flash again. This indicates the new key fob has been programmed.
- Repeat for Additional Key Fobs: If you have more key fobs to program, repeat step 3 for each one.
- Exit Programming Mode: Turn the ignition to the “OFF” position. Test all programmed key fobs to ensure they function correctly.
