Dealing with key issues for your 2004 Ford Taurus can be frustrating, especially when faced with expensive key fob programming costs. If you’re looking for a less costly alternative, particularly if you only have one working PATS (Passive Anti-Theft System) key, this DIY bypass method might be a solution for you. Keep in mind that this approach involves a security compromise, similar to using a remote starter with a PATS bypass. If you understand and accept this potential risk, proceed with the following steps.
Steps to Potentially Bypass the PATS System on Your 2004 Taurus
This method involves tricking your car’s security system into thinking a valid key is always present.
-
Acquire Generic Keys: Obtain at least two non-transponder, flat keys cut to match your existing key’s specifications. These can be made at most locksmiths or key cutting services.
-
Access the Ignition Cylinder Area: Carefully remove the transceiver ring that surrounds your car’s ignition cylinder. This ring is responsible for reading the transponder chip in your key.
-
Prepare Your Working PATS Key: Take your existing, functional PATS key and position it directly inside the transceiver ring you just removed. Secure the key in this position using plastic cable ties to ensure it stays consistently within the ring’s detection range.
-
Conceal the Key and Ring Assembly: Find a secure and hidden location within your car’s dashboard to place the transceiver ring with the secured PATS key. The goal is to make it difficult to access easily, further reducing the already accepted security risk.
-
Reassemble and Test: Carefully reassemble the components you removed from around the ignition cylinder, ensuring everything is back in its place except for the transceiver ring assembly which is now hidden with the PATS key. Use your newly cut generic keys to start and operate your 2004 Ford Taurus. The hidden PATS key should continuously satisfy the security system, allowing the generic keys to function.
Important Considerations
While this method can bypass the need for expensive key programming, it’s crucial to understand the trade-offs. This method reduces your vehicle’s theft security to a level comparable to vehicles with remote starters utilizing a PATS bypass module containing a live key. For enhanced security and proper key functionality, consulting with a professional locksmith or Ford dealership for genuine key programming is always recommended.
