The only way to unlock the radio is by using a scan tool. The scan tool sends the appropriate diagnostic message (relearn VIN) to reset the radio. Using a scan tool, select the radio VIN relearn procedure from the module replacement screen in Vehicle Control Systems

Unless the car is overheating you probably just have a bad temperature sensor probably located on the intake manifold....

Start at $89 right off the bat just for diagnostics and then depending on what they find that is causing that fault, at LEAST one hour labor, plus parts....I would say $250 is a good ballpark figure....looking up your fault code now.

This code is for your Coolant Thermostat - It's detected that the Coolant Temperature is below the Thermostat Regulating Temperature

Testimonial: "Very helpful thanks a lot."
you could shotgun both parts and replace both...or just remove the thermostat. place it in a pot of water with a thermometer and warm it up. watch when it opens. if it opens before the temp stamped on the theormostat then it is bad and will not require replacement of the temp sensor. If it opens at the temp on the t-stat then replace the sensor. Rarely caused by sensor. Mostly caused by t-stat. no need to spend the money on both when you only need one.

This means that the engine's PCM detected that the engine has not reached the required temperature level within a specified amount of time after starting the engine. The intent of the P0128 code is to indicate a faulty thermostat. Similar codes: P0125
In determining the engine did not reach a "normal" temperature, it takes into account the length of time the vehicle has been running, the intake air temperature (IAT) sensor reading, the engine coolant temperature (ECT) sensor reading, and the speed of the vehicle.
A code P0128 may mean that one or more of the following has happened:
Past experience indicates that the most likely solution is to replace the thermostat. However here are some suggestions on troubleshooting and repairing a P0128 OBD-II code:
I hope this helps a bit!
