It has been awhile since I have blogged about a useless fact of the day. Today's useless fact of the day is about car keys again. This time it is related to Freightliner keys in a way.
In 1970 American Motors Corporation or AMC, debuted a new car key design that looks almost identical to a General Motors key. In fact the keys are the same shape and size but the most notable difference is that the AMC keys have a deeper groove on them. The groove is a bit bigger and lower than the groove on the General Motors key. Both keys were made by Briggs and Stratton, which was the biggest supplier of OEM car keys at that time.
Here's the kicker about American Motors keys, the ignition key has also been used by heavy duty truck manufacturers to this very day. Those companies who shared the same keys, are Freightliner, Western Star, International Harvester, International Trucks, and Mack Trucks, even Volvo used the single cut key at one point. The OEM key name for the American Motors key is 1970AM hence the year 1970 in the name of the key part code.
