Lincoln Repair Questions? Ask a Mechanic for Answers ASAP
Do you have a scan tool to pull trouble codes?
That's going to make it a little tricky, but not impossible.
First, check for a blown fuse #34 in the under hood fuse box.
If all of the fuses look ok then the only thing left to do is communicate with the theft module- we'll need a scan tool- a good scan tool- to do this.
Ok. I've seen the number #34 fuse blow from a shorted harness causing a communication problem with the PATS (security key) system. It was a long shot, but I've seen it enough to make it worth checking.
Do you have an automotive locksmith in your area? Without a scan tool that will be the next step. We need to see if the PATS system is communicating correctly and if the keys are transmitting a strong signal.
We also need to see if the two keys that you have didn't somehow lose programming in the system.
Sometimes the keys just lose programming for no reason at all. We see this fairly often. An automotive locksmith or dealer will be able to hook up a scan tool and communicate with the security system to see what is going on.
Most locksmiths will come to you, but yes, they will need to plug into the vehicle.
These theft systems can be such a pain when they malfunction.
