Losing a key fob or needing an extra one for your 2004 Ford Taurus can be a hassle, often leading to expensive dealership visits. While professionally programming a key fob is generally recommended for security and reliability, some car owners explore DIY methods to save money. This article examines a less conventional, do-it-yourself approach that leverages your existing Programmable Anti-Theft System (PATS) key. Please be aware that this method is a workaround and carries potential security risks.
This method, shared by some car enthusiasts online, is not traditional key fob programming. Instead, it involves bypassing the standard key recognition process by permanently placing a working PATS key near the ignition system. This allows generic, non-programmed keys to start your 2004 Taurus.
Here’s how this workaround is described:
-
Get Generic Keys Cut: First, have at least two non-transponder, generic keys cut. These keys should match the mechanical cuts of your existing PATS key but will lack the embedded microchip. You can get these cut at most locksmiths or hardware stores.
-
Locate and Access the Transceiver Ring: The transceiver ring is a component of your car’s PATS system. It’s usually located around the ignition cylinder. You’ll need to carefully access the area around your steering column to find it. Consult your 2004 Ford Taurus repair manual for specific location and access instructions.
-
Prepare Your PATS Key and Transceiver Ring: Once you’ve accessed the transceiver ring, carefully detach it from its mounting. Take your original, working PATS key and position it directly inside the transceiver ring.
-
Secure the PATS Key: Use plastic cable ties or another secure method to firmly attach your working PATS key within the transceiver ring. Ensure the key is positioned so that the transceiver can consistently read its signal.
-
Conceal the Assembly: The key and transceiver ring assembly now needs to be hidden inside the dashboard. Choose a location that is difficult to reach easily but won’t interfere with any vehicle operations or moving parts. Secure the assembly in this hidden location.
-
Reassemble and Test: Carefully reassemble the components you disassembled to access the transceiver ring. Now, use one of the generic, non-programmed keys you had cut. Start your 2004 Ford Taurus. If the procedure is successful, the hidden PATS key will be recognized by the system, and your generic key will start the car.
Important Considerations and Risks:
This method is a security compromise. By permanently bypassing the PATS key verification, you are essentially disabling a layer of your car’s anti-theft system when using generic keys. While it might seem like a cost-effective solution, consider these drawbacks:
- Reduced Security: Your car becomes easier to steal if someone gains access to generic keys that can start the vehicle.
- Potential System Issues: Tampering with the PATS system, even in this way, could potentially lead to unforeseen electrical issues or malfunctions in your car’s security system.
- Not True Key Fob Programming: This method does not program a new key fob to your car. It merely circumvents the need for key programming by always having a valid key present.
A Safer, Recommended Alternative:
For true key fob programming and to maintain your vehicle’s security, it is strongly recommended to have key fobs professionally programmed. You can visit a Ford dealership or a certified locksmith specializing in automotive key programming. They have the proper tools and expertise to securely program new key fobs to your 2004 Ford Taurus, ensuring your vehicle’s security system remains intact and functional as intended.
While the DIY method described offers a workaround, the security risks and potential complications make professional key fob programming the wiser and more reliable choice for your 2004 Ford Taurus.
