2006 Volvo C70 Remote Flip Key Replacement - Fast, Affordable & Professional

I got a call from a guy over in Bear Valley who had already paid another locksmith to replace his key on a 2006 Volvo C70. The car would crank, fire for half a second, then die. Every single time. The other locksmith told him the CEM was bad and walked away.

He found me through a neighbor and was pretty skeptical by the time I pulled up. Understandable. He had already spent money and still had a car that would not start.

I asked him to walk me through exactly what the first locksmith did. OBD connection, wrote a key, done. That told me everything. On this generation of Volvo, that workflow is incomplete on an all-keys-lost job. The CEM stores secured registration data that an OBD-only approach cannot reach without first reading the module on the bench.

I pulled the CEM, read it on the bench with my programmer, extracted the data, generated the correct key information from the dump, wrote it back, reinstalled the module, and then finished the registration sequence through the diagnostic port. His existing flip key, the five-button fob with the factory FCC ID on the label, was the key we registered. No new fob needed.

Three consecutive start cycles. Clean every time. I showed him the confirmation screen on my equipment so he could see the key listed as registered.

He had already paid someone else and gotten nothing. What I charged him was still a fraction of what the dealer quoted, and the job was actually done this time. He did not say much. He just started the car a fourth time on his own, smiled, and said "yeah, that's it."
