Key fob does not work

[trademark83]

I have a 07 . The key fob does not lock/unlock the door. What can I check to diagnose problem?

The fuse are fine. I checked the fuse box that is under the glove compartment. The power locks still work when pressing the button inside the car.

Did you try replacing the battery?

I tried the other key fob that I never use, does not work.

I'd still attempt replacing the battery that can be bought at Walmart for very little.

The replacement takes 2 minutes.

get new batteries then reprogram them, it takes 30 seconds. I've done this several times in the past few years


Step 1: Open driver side door and leave open.
Step 2: Lock and Unlock the drivers door using the power door lock switch on the door
Step 3: Insert key into the ignition.
Step 4: Turn Key to ON position and return to Lock (off) position. Do this 3 times within 10 seconds. LEAVE key in the ignition in Lock (off) position.
Step 5: Close and open the drivers door 3 times. Leave door open after this step
Step 6: ECU should respond by locking and unlocking the doors once.
Step 7: Press any button on remote #1 twice. ECU responds by locking and unlocking the car doors.
Step 8: Additional remotes, repeat Step 7 for up to 3 remotes total.
Step 9: Remove the key from the ignition and the ECU will respond a final time with a series (about 4) of door locks and unlocks. You're done!
