Security light flashes car won't crank
How to reset security

The 2005 Impala was the last of its generation, and therefore saw few changes. Among these changes was that OnStar was now a standard feature on all trims, a popular enhancement among Impala drivers.
Engines remained the same: a 3.4-liter, 180 horsepower V6 for the standard sedan, a 3.8-liter, 200-horsepower V6 for the LS, and a 3.8-liter, 240horsepower V6 for the SS.
Drivers love the solid handling, rapid acceleration, and all-over peppy drive. Some have complained that the car does not approach is estimated 21 city/32 highway mileage (20/30 and 18/28 for the LS and SS), yet many seemed pleased with the efficient gas mileage accompanying the strong engine.
All trims now come standard with driver, passenger, and side airbags, creating a safe environment for the up to six passengers inside the car.

Do these cars come with any kind of warranty? Guaranteed to pass initial state inspection? Thanks.
I replaced the coolant temp sensor and thermostat now the coolant fans won't stop and the dashboard temp gauge stopped working.
