Another game involved 10 keys with the contestant having to choose the key (with a set number of chances) that opens the large "vault" containing the car inside (similar to The Price Is Right ' s "Master Key" and "Safe Crackers" pricing games). In 1995, the "vault" changed color from gold to blue. In 1999, a relaunch of the game had all the finalists choose one key each and was expanded to 16 keys, whilst the 2006 relaunch returned to the old format, but with a makeover (it resembled a bank vault and the keys in-game were modeled after real keys). From 1993-95, a giant die rolled from the bleachers determine the number of keys to pick (a fish bowl was used from 2006–08). If the vault opens in which they pick the winning key number, a siren went off and the contestant wins the car. Otherwise, the buzzer will sound if the vault does not open in which the contestant picks the wrong key number (with Don Francisco showing the audience the winning key number in an envelope and, occasionally, using that key to open the vault). There have been multiple occasions where contestants won the car on the first/only key. This game was considered the most popular car game of the show and is the first car game played. This game now appears occasionally, with all finalists each picking the key they believe opens the car door. And if the car door opens, they will win a new car. During gameplay, whenever contestants are on their sole/final key, Don Francisco would offer a cash prize (up to $2000) in exchange for their key (there have been multiple instances where contestants picked the winning key but took the cash prizes). The final episode in September 2015 had a guaranteed winner of a car, as five members of the audience were allowed to pick a key from a bowl and try it in the door lock. The third contestant was successful.
