General Motors Keying Kits

Servicing General Motors vehicles has become much more difficult for the automotive locksmith. In the past, all General Motors locks, no matter who manufactured them, could use the same tumblers and springs. Over the last several years, lock manufacturers do not appear to have this restriction. The result is that vehicles are being equipped with locks that are using different tumblers, springs and retaining components. Without prior knowledge, there is no way to know who makes the lock or what wafer tumblers or springs are necessary. This has proven to be a nightmare for locksmiths.

For me, it started when Saturn began using locks manufactured by Huf in 1997. The wafers and springs used in the previous locks manufactured by STRATTEC and BWD were not interchangeable with the Huf wafers or vice versa. At that time, the only place to obtain the Huf tumblers was from a Saturn dealership. The cost: almost $2 a tumbler and more than $1 per spring. Combinating an ignition lock using the Saturn dealer components cost between $20 and $30, and that was just for the parts, not the time to drive to the dealership or to combinate the lock. I was told by the dealership that I could purchase a keying kit for just a little over $500 at their discounted price.

Aftermarket locksmith companies A 1 Security Manufacturing and ASP came to the rescue by introducing keying kits for a lot less.

Since Saturn in late 1997, General Motors continues to change who builds the domestic vehicle models locks. The three major lock manufacturers are Huf, Ortec, and STRATTEC. STRATTEC sells lock service packages, tumblers and springs, and some keying kits for General Motors vehicles through locksmith distribution. The aftermarket distribution of locks and parts made by other manufacturers, such as Huf and Ortec, are not as well organized and the information is not always complete or accurate for the locksmith market. To make matters worse, Huf and Ortec locks can vary by model as well as by year, making it extremely difficult to know which wafer tumblers fit what locks.

Many of the General Motors ignition, door, deck, and compartment locks are designed to interchange as complete units. However, the internal components such as the wafer tumblers, springs and spring retainers do not.

In an attempt to make this easier, A1 Security Manufacturing and ASP sell keying kits and replacement tumblers and springs for a number of General Motors vehicles. The A1 keying kits are comprised of original equipment wafer tumblers, springs, and retainers. The ASP keying kits of are comprised of original equipment and manufactured wafer tumblers, springs, and retainers. The A1 and ASP keying kits contain 25 of each depth of wafer tumbler.

For the purpose of this article, we will discuss only vehicle models that are not manufactured by STRATTEC. Note: Vehicle manufacturers make changes to their lock mechanisms. The A1 Security Manufacturing and ASP keying kits are not guaranteed to operate all of the new vehicle production and any aftermarket changes.
