The disc tumbler variation is not typically found in automotive locks. Automotive locks primarily use either pin tumblers or wafer tumblers for their locking mechanisms.

Pin tumblers consist of a series of pins that must be aligned to a specific height for the lock to open. This type of system is reliable and commonly utilized in vehicles. Wafer tumblers, on the other hand, employ flat wafers that must be aligned to permit the lock to turn, which is also a frequent choice for automotive applications.

While side bar wafers can sometimes be incorporated in more advanced locking systems, they are not as prevalent as the basic tumbler mechanisms currently used in most cars. Disc tumblers, though utilized in some other lock types, such as padlocks and vaults, are not designed for or typically found in automotive locks.
