Some Chrysler models during 1959-1965 used a “CV” series, GM-type sidebar trunk lock with an Ilco 1759P keyway.
GM KEY CODES SERIES
From 1956-1967 Chrysler used a “CJ” series with the Ilco X1199J keyway.
GM KEY CODES CODE
From 1949-1955 Chrysler used a “CB” code series with the Ilco X1199G keyway. Chrysler used a “CA” code series from 1947-1948 but still used the X1199B keyway. Chrysler standardized on a “BP” code series using the Ilco X1199B keyway from 1939-1946. These two models used a key system with all locks keyed alike.ġ933-34 Omega key blanks are no longer made, but every car key blank used since 1935 is still listed in the Ilco key catalog.
Another exception was GM Chevrolet and Buick models in the 1950s. A third key was used for locking Chrysler glove box locks which had a wafer lock with a 1098X keyway. Trunk locks and glove box locks were keyed alike but used a separate key code. Ignition and door locks were generally keyed alike. Aftermarket key manufacturers still produce key blanks for 95 percent of these old cars and key codes are readily available. With the exception of Chrysler locks, most car locks made from 1935 to 1970 had key codes printed somewhere on the cylinder housing. During this same period, many of the smaller companies such as Nash, Hudson and Packard used Briggs & Stratton five tumbler wafer locks. Early wafer-type auto locks used double-sided keys, but the use of bi-directional double-sided keys had to wait until 1965 when Ford introduced their double-sided pin tumbler lock systems.Ĭhrysler and Ford began using pin tumbler lock systems in the 1930s. Pin tumbler lock systems were popular during the 1920s with manufacturer names such as Yale, Sargent, Corbin, Russwin and Eagle leading the way. The last big change in auto lock designs was probably the GM locking sidebar system and that first appeared on 1936 GM models. Until sidewinder locks and transponders appeared on the scene, automotive lock systems had remained unchanged for more than 60 years.
