问题     Technology was supposed to set us free, but in the car industry it’s locking us out of our vehicles. And as many more car keys contain electronic chips and come equipped with computerized anti-theft ignition systems, this problem looks set to worsen, experts say.
    The days of visiting a hardware store for an extra car key are quickly vanishing, and consumers and advocacy groups say the time needed to replace missing or lost electronic keys is inordinately long and expensive — and drivers may have no recourse (求助对象) when dealerships are not open. Getting a new electronic key can cost hundreds of dollars, including the cost of towing a car.
    Unlike an old-fashioned mechanical key, which unlocks a door or starts an ignition with its "teeth", an electronic car key works by sending a code that must be read electronically before a vehicle’s engine will start. The technology for these keys is evolving rapidly and only a few locksmiths are investing in the technology needed to replace them, meaning most drivers who lose their keys are forced to visit a dealership for a replacement.
    In a study of the cost of replacing keys in 50 makes and models of vehicles in the Washington, D.C. area, Ditlow’s group found that the average cost of an old-fashioned mechanical key was $12, while the average local dealer price of a "smart" or electronic key was $152. The highest key replacement cost was $335 for a 2004 Lexus IS300.
    Ditlow speculates that with a healthy profit coming from their service and parts replacement divisions, auto companies are reluctant to make the codes for their electronic keys more readily available. For their part, automakers say making the information readily accessible would lessen the effectiveness of their anti-theft systems. To remedy this, Ditlow has suggested that the National Insurance Crime Bureau, which combats theft and insurance fraud, maintain a database of key codes so they can be easily located.
    Some automakers do indeed provide their information, but not all. And as automobile electronics become increasingly sophisticated and increasingly common, the electronic key problem looks set to continue to dog drivers, experts say. Most luxury cars now have sophisticated electronic key systems, and car lockouts are among the most common reasons for roadside-assistance calls according to the AAA.
How does a car react at first to the code signal of an electronic car key?
选项
答案It reads the code electronically．
解析 根据题干中的the code signal of anelectronic car key将本题定位在第三段第一句。该句后一个分句描述了电子钥匙的点火方式，其中提到，电子车钥匙会发出一个密码(sending a code)。code的定语从句表明，这个密码必须以电子的方式读取(a code that must beread electronically)，才能启动汽车。所以汽车对钥匙的密码信号作出的第一反应是以电子方式读取密码。
