During the early 1960s, these special keys became so popular that oil companies like Mobil, Texaco, and Union 76 began issuing their own logoed versions as promotional items for their customers. These were automotive keys that featured an enameled rendition of the auto manufacturer's logo on the bow and were plated in 14k gold. Key also produced keys for many 1950's-1970's makes and models known as " Crest Keys". Signa-Craft and other manufacturers like Curtis, Taylor Locks, and Mr. automaker's prototype "Dream Cars" like the Pontiac Strato-Streak and the Cadillac El Camino featured on them. In the 1950s, early versions of "flip keys" resembling jack knives were made by the Signa-Craft company out of New York with various period U.S. Aside from the convenience to the driver, this starter makes it impossible for children to move a car which has been left in gear by pushing the starter button. When released, the key automatically returns to 'ignition on'. The car starts by turning the ignition key slightly beyond the 'ignition on' position. Popular Mechanics, in April 1949, wrote:Īmong the innovations of primary interest to the driver is the combination ignition and starter switch which eliminates the starter button. Because switchblade keys are only developed for new car models, they are usually equipped with a programmed transponder chip.Īutomobiles had door keys earlier, but the first ignition keys that also operated the starter mechanism were introduced by Chrysler in 1949. These type of keys are also commonly referred as Flip Keys. Switchblade keys have become very popular recently because of their smart compact look. The switchblade key is designed to fold away inside the fob when it is not being used. These keys can be expensive to replace if lost and can cost up to US $400.Ī switchblade key is basically the same as any other car key, except in appearance. If the codes match, the car can be started. Mercedes-Benz uses a key that, rather than have a cut metal piece to start the car, uses an encoded infrared beam that communicates with the car's computer. Some high-tech automotive keys are billed as theft deterrents. Some of them are handsfree in that a vehicle door is automatically unlocked when the user's handheld device is detected within proximity to the vehicle. Keyless entry systems, which use a door-mounted keypad, key fob, a wireless-enabled handheld computing device (e.g., smartphone or tablet), or a remote control in place of a toothed key, have become a standard feature on most new cars. In the latter, the switch is between the seats, preventing damage to the driver's knee in the event of a collision. Ignition switches or locks are combined with security locking of the steering column (in many modern vehicles) or the gear lever (such as in Saab Automobile vehicles). A number of these systems, such as KeeLoq and Megamos Crypto have been demonstrated to be weak and vulnerable to cryptanalytic attacks. More sophisticated systems make ignition dependent on electronic devices, rather than the mechanical keyswitch. Recently, features such as coded immobilizers have been implemented in newer vehicles. Some valet keys, particularly those to high-performance vehicles, go so far as to restrict the engine's power output to prevent joyriding. Some cars come with an additional key known as a valet key that starts the ignition and opens the driver's side door, but prevents the valet from gaining access to valuables that are located in the trunk or the glove box. A car key can open the doors, as well as start the ignition, open the glove compartment and also open the trunk (boot) of the car. It has multiple uses for the automobile with which it was sold. Modern key designs are usually symmetrical, and some use grooves on both sides, rather than a cut edge, to actuate the lock. A car key or an automobile key is a key used to open and/or start an automobile.
