RTT Devious Decoder Card - North American Version
The RTT Devious Decoder Card (DDC) is a compact, professional measuring tool that combines key-blade and pin-stack gauges into a single, wallet-sized instrument. Now upgraded to laser-etched stainless steel for extreme durability and precision, the North American DDC gives locksmiths, technicians, and security pros a fast, reliable way to measure bitting depths, key pins, and master pins for common U.S. key systems—without carrying bulky calipers or multiple gauges.
Key Details
-
Laser-etched stainless construction: Upgraded from earlier resin versions to corrosion-resistant stainless steel with laser marking for permanent, high-contrast graduations.
-
Dual-purpose stair-step cutouts: Unique stepped apertures accept both key blades and individual pins, letting you read bitting cut depths and pin lengths from one tool.
-
North American focus: Includes measurement profiles and apertures suitable for Schlage, Kwikset, Master Lock, and American Lock families (Master/American share compatible pin gauges).
-
Credit-card form factor: ISO/IEC 7810 size (3⅜" × 2⅛") fits wallets, badge holders, or tool pouches for convenient carry.
-
Wear-resistant, non-magnetic inserts: Apertures are finished with non-magnetic, wear-resistant inserts to maximize life and avoid magnetic interference with sensitive components.
-
Fast field use: Ideal for on-site decoding after impressioning or picking, rapid inventory of pin stacks, or confirming key bitting without expensive instruments.
