YAMAHA KEY PROGRAMMER ADAPTER

Jaltest JDC661M - Yamaha Key Programmer Adapter

The JDC661M is a Cojali Jaltest key programming adapter for Yamaha personal watercraft and marine engines. This adapter works within the Jaltest Marine software platform to enable key programming functions on Yamaha watercraft equipped with electronic key systems. For marine shops that service Yamaha jet skis and need the ability to program replacement or additional keys in-house — rather than routing customers to a Yamaha dealer — this adapter is the required tool.

What This Adapter Does

The JDC661M is used in conjunction with the Jaltest Link V9 and the Jaltest Marine software to perform key programming on Yamaha personal watercraft. Key programming is a dealer-level function, and the JDC661M gives Jaltest users access to this capability for Yamaha applications.

Adapter Specifications

• Part Number: JDC661M
• Application: Yamaha personal watercraft — key programming
• Link Version Compatibility: Jaltest Link V8.1 and V9
• System Compatibility: Jaltest Marine (Jet Ski or Full license required)
• MSRP: $125.00

Included In the Jaltest Jet Ski Cable Kits

The JDC661M is a component of both official Jaltest Jet Ski cable kits per the 2025 Jaltest Pricelist:

• Jet Ski Cable Kit Without Yamaha Cable (Part #29985, $585.00) — includes JDC661M along with JDC602A, JDC610A, JDC641M, JDC660M, and JDC618A9
• Jet Ski Cable Kit With Yamaha Cable (Part #29986, $690.00) — adds JDC601A and JDC662M

Purchasing the JDC661M individually makes sense for shops that already have most of the jet ski kit or are adding Yamaha key programming to an existing Jaltest Marine setup.

Why Key Programming Matters for Marine Shops

Lost keys are a common customer problem with Yamaha personal watercraft. Without the ability to program a replacement key in-house, the customer has to go to a Yamaha dealer — and that job leaves your shop. The JDC661M, paired with an active Jaltest Marine license, lets you handle Yamaha key programming yourself. That is a real service capability that adds to your shop value for Yamaha watercraft owners.

Who Needs the JDC661M

Any marine or powersports shop using the Jaltest Marine platform that services Yamaha personal watercraft and wants key programming capability. Works alongside the JDC601A (Yamaha diagnostics cable) for complete Yamaha jet ski coverage within Jaltest Marine.
