2006 Chrysler Pacifica Remote Head Key Replacement - Fast, Affordable & Professional

I got a call from a woman parked outside the gymnastics studio near Marina West in Oxnard. Her 2006 Pacifica would not crank. She had already done the logical thing, replaced the CR2032 in the key head, because the lock and unlock buttons had been getting weak. New battery, buttons worked fine, car still would not start. She was forty minutes from the next pickup and had kids at two different places.

She told me the dealer said Friday. It was Tuesday afternoon.

I pulled up to the lot, popped the OBD connector, and ran the transponder enrollment sequence through my programmer. The key she had was the correct factory remote head key with the right blade for the Pacifica, so we were not waiting on parts. The issue was that the transponder had lost its pairing to the immobilizer, which happens on these occasionally, especially if someone has tried to start the car repeatedly with a key that was already marginal on the chip side.

Programming finished in under twenty minutes. I verified start, cycled it twice more to confirm it was stable, and tested all four buttons while I was there.

She made her pickup with time to spare. The dealer route would have meant a tow, a wait for a parts order if they did not have the key in stock, a place in the service queue, and a bill that made her wince when she described it. She called back two weeks later about a second key, which is always the smarter move once you have already paid for the first programming session.
