Why did my programmed key only start my car once?
I Ii have a 2006 ford tauras i had to replace the ignition cylinder it came with keys that i had programmed but the key only worked once and now it wont start the car again

The biggest change to the 2006 Ford Taurus is the loss of the wagon model and the Duratec DOHC V6 engine. Available only as a four-door mid-sized sedan, there are two trims -- the SE and SEL. Both come with a 153-hp, 3.0-liter V6 and 4-speed automatic. Unable to compete with foreign sedans in its class, the previously popular, but outdated family sedan was quickly supplanted by the snazzier Ford Fusion and more upscale Five Hundred.
The Taurus is far from flashy and offers the most basic functional features. Its highlight is its roomy interior, which can hold up to six passengers. While the base model SE comes with power features, cruise control, and keyless entry, the SEL upgrades the look with wood accents, a power driver's seat, and a CD player. The 2006 Taurus earns top ratings for front impact, thanks to dual front airbags, but only earns three stars for side impact. Front-side airbags can be added, along with ABS and traction control. Bundled packages adds more luxuries, such as leather seats, a power passenger seat, and a CD changer, and a rear spoiler can be added to cut through the exterior blandness of the front-wheel drive sedan.
The 2006 Taurus may be showing its age, and it never achieved the cult status of the Honda Accord, but it has proved to be a fairly reliable sedan over the years, despite suffering from rapid depreciation. Acceleration can be labored, and some drivers report inadequate brakes and brake shudder, but the comfort, features, and passenger room are still highlights. 2006 will be the last year for the Taurus until 2008, when the Five Hundred and Fusion will be revived under the Taurus name.

My daughter was turning over her 2006 Ford Taurus, when all the dash lights went out and all power has been lost (can't get headlights to turn on either). Checked the battery and it has a charge, so I don't think that is the issue. I am just looking for other possible things to check out. I have looked at some fuses (starter fuses) and the 15A internal box fuse looks fine as well as the 40A in box under the hood. Any thoughts/suggestions would be greatly appreciated.
I have a Ford Taurus 2006. When I start it it will crack but wont stay started. This just happened out of the blue.
how can you tell if key has a chip in it
