Instructions for Automotive Locksmith Tools


Due to the high cost of automotive locksmith tools, it is difficult for locksmiths to collect all types.

To comprehensively master the characteristics of various automotive locksmith tools, we will begin by introducing the types of car keys.

 

From the perspective of appearance and shape, car keys can be broadly categorized into the following types:

1. Double-Sided Key (Standard Key)

Keys with cuts on both sides. A common type widely used in multiple brands, such as TOY43 、CY24、MAZ24、DWO4、GM39 etc.

2. Groove Key (Laser Key)

Named for grooves cut into the key blank, Mainly subdivided into:

(1) Double External Groove Key (e.g., 4-track external)

Grooves cut into the outer four directions (top-left, bottom-left, top-right, bottom-right) of the key blank. Groove patterns are typically complex, offering higher

security. such as HON66、HU39、HON77、HU58、DAT17 etc.

(2) Double Internal Groove Key (e.g., 4-track internal)

Grooves cut into the inner four directions (top-left, bottom-left, top-right, bottom-right) of the key blank. Requires high precision in depth and angle. Compared to

external groove keys, the wafer or sidebar mechanism inside the lock cylinder is usually more compact. such as TOY48、TOY40、HY22、MAZ23、HON60 etc.
