2003 Chrysler Concorde Transponder Key Replacement - Fast, Affordable & Professional

I was parked on a street just off Hot Springs Road on a Sunday morning. A woman flagged me down before I even finished setting up. She had a 2003 Chrysler Concorde and a story I have heard before.

A locksmith had already come out. Cut her a new key, charged her full price, left. The car would crank, run for two seconds, then die. Every time. The other guy told her the car had a module problem. She had already been looking at tow quotes.

It did not have a module problem.

The 2003 Concorde immobilizer does a security handshake at startup. If the key is not properly learned to the module, or if the PIN exchange was incomplete, the system lets the engine fire briefly and then kills it. Classic interrupted learn. The car was doing exactly what it was supposed to do.

I connected through the OBD port, pulled the PIN directly from the immobilizer module, cleared the bad key data the previous tech had left behind, and ran a clean learn with the full security cycle completed. Then I turned the key and let it idle. Thirty seconds. A minute. No stall.

She stood there watching the tachometer like she was waiting for it to lie to her. It did not.

I showed her the confirmation on the scan tool screen so she could see for herself that the key was fully written this time, not temporarily accepted. She had already paid someone else for a job that was never finished. I could not fix that part. But she drove home.
