Ford Mustang key fobs for keyless entry programming
Essential Materials
Before you begin the programming process, gather these simple materials:
- New Batteries: Ensure your key fob has fresh batteries for optimal performance during programming.
- Paper Clip: A standard paper clip, bent into a 90-degree angle, will be needed for 1994-1998 Mustang models.
- Key Fobs: Have your new key fobs ready. You can program up to four fobs for 1994-1998 models and you will need at least two for 1999-2004 models.
Programming Your 1994-1998 Mustang Key Fob
These steps are for programming key fobs for Ford Mustangs manufactured between 1994 and 1998.
Step 1: Install New Batteries in Your Key Fob
Start by replacing the batteries in your key fob. This ensures that a weak battery doesn’t interfere with the programming process.
Step 2: Access the Keyless Entry Module
- Open the Trunk: Begin by opening the trunk of your Ford Mustang.
- Remove Trunk Panels: Locate and remove the rear trunk panel and the driver’s side trunk panel. This will give you access to the keyless entry module.
- Locate the Two-Prong Plug: Identify the two-prong plug on the keyless entry module. It is held in place by a push pin.
- Remove the Pin: Carefully remove the push pin securing the plug. You should be able to remove it by hand.
- Identify Terminals: The plug terminals should now be visible and easily identifiable.
Step 3: Enter Programming Mode
- Turn Ignition to “ON”: Get into the driver’s seat and turn your Mustang’s ignition key to the “ON” position. Do not start the engine. If you have someone assisting you, they can handle this step.
- Short the Connector: Take your paper clip, bent into a 90-degree angle, and insert it into the connector plug. Make sure the paper clip touches both terminals to create a short circuit.
- Wait for Training Mode: Listen for your Mustang to enter training mode. The door locks will cycle (lock and unlock) to indicate that the system is ready for programming.
Step 4: Program Key Fobs
- Press Button on First Fob: Press and hold any button on your first key fob (like the lock or unlock button).
- Confirm Programming: The door locks will cycle again, confirming that the first key fob has been successfully programmed to your Mustang.
- Program Remaining Fobs: Repeat the previous step for each additional key fob you want to program.
- Remove Paper Clip: After programming all key fobs, reach back into the trunk and carefully remove the paper clip from the connector.
- Turn Ignition “OFF”: Turn the ignition key back to the “OFF” position.
- Test Key Fobs: Test each key fob to ensure they are working correctly by locking and unlocking your doors and trunk.
Programming Your 1999-2004 Mustang Key Fob
If you own a Ford Mustang from 1999 to 2004, including the 2004 model, follow these steps to program your key fobs. You will need at least two working key fobs for this procedure.
Step 1: Prepare for Programming
- Gather Key Fobs: Ensure you have at least two factory or aftermarket keyless remotes ready.
- Enter the Vehicle: Sit in the driver’s seat of your Mustang with your key fobs.
Step 2: Cycle Ignition to Enter Programming Mode
- Turn Ignition “OFF” to “RUN” Eight Times: Quickly turn your ignition key from the “OFF” position to the “RUN” position eight times consecutively within 10 seconds. On the eighth turn, leave the key in the “RUN” position. Do not start the engine.
- Listen for Door Locks: After the eighth cycle to the “RUN” position, you should hear your vehicle’s door locks cycle (lock and unlock). This indicates that your Mustang has entered programming mode.
Step 3: Program Key Fobs
- Press Button on First Fob: Take your first key fob and press any button (like “LOCK” or “UNLOCK”). This action will program the first remote to your Mustang.
- Press Button on Second Fob: Immediately take your second key fob and press any button. Listen for the door locks to cycle again, confirming the programming of the second key fob.
- Program Additional Fobs (Optional): If you have additional key fobs to program, you can do so at this time by pressing a button on each, listening for the door locks to cycle after each press.
- Turn Ignition “OFF”: Once you have programmed all desired key fobs, turn the ignition key to the “OFF” position.
- Test Key Fobs: Test each programmed key fob to verify they are working correctly by locking and unlocking your doors and trunk.
Troubleshooting Tips
- Battery Issues: Always start with fresh batteries in your key fobs. Weak batteries can cause programming failures.
- Timing is Key: For 1999-2004 models, the timing of turning the ignition between “OFF” and “RUN” is crucial. Ensure you are performing the eight cycles within 10 seconds.
- Module Location: If you are having trouble locating the keyless entry module in 1994-1998 Mustangs, consult your vehicle’s repair manual for precise location diagrams.
- Professional Help: If you encounter persistent issues, consider seeking assistance from a professional locksmith or mechanic specializing in automotive key programming.
