2000 Lincoln Continental Transponder Key Replacement - Fast, Affordable & Professional

Got a call from a woman in the Wildwood neighborhood of Thousand Oaks. She had a 2000 Lincoln Continental sitting in her driveway that would crank but not fire. The dash was throwing the theft light, solid and steady, which on PATS 2 means the system is not reading a valid transponder at all.

She had two keys. One she had been using for years and one from the previous owner that she kept in a drawer. Neither would start the car.

I pulled up and checked the obvious stuff first. Put the key in the ignition, turned to RUN, watched the theft indicator. Solid on, no flash sequence. That told me the PATS transceiver ring around the ignition cylinder was not picking up the 4C chip in the key. I tested both keys with my transponder reader on the hood. The everyday key read dead. The drawer key still had a live 4C chip.

Swapped to the drawer key, turned to RUN, and the theft light did its normal prove-out and went off. Engine started clean.

I cut a fresh H72-PT blank, programmed the new 4C chip to her PATS module using the one surviving key plus the diagnostic port, and handed her two working keys. The whole job took about 35 minutes in the driveway.

She almost tossed that drawer key a dozen times over the years. Good thing she never did.
