Hillman Fasteners 449057 Transponder Key K169

Product Description

The HILLMAN FASTENERS 449057 is a DuraKey transponder key blank designed for automotive and security key replacement applications. Transponder keys contain an embedded microchip that communicates with a vehicle's immobilizer system, allowing the engine to start only when the correct signal is recognized. This key blank is sold in a package quantity of 20 units, making it a practical supply for locksmiths, automotive service shops, and key duplication professionals who handle high-volume cutting and programming work.

This transponder key blank fits into professional key cutting and programming workflows where OEM-style replacements are needed. The K169 designation identifies the key blade profile, which determines mechanical fit at the ignition cylinder. Locksmiths and automotive technicians rely on DuraKey blanks for consistent quality across high-turnover replacement jobs. The 20-count pack is suited for shop stock rather than single-use purchase.

Key Features

• Transponder key blank with embedded microchip for immobilizer system compatibility

• Sold in a 20-unit pack, ideal for shop inventory stocking

Compatibility

Designed as an OEM-style replacement transponder key blank for vehicles requiring the K169 key blade profile. Confirm vehicle compatibility and transponder chip type before cutting and programming.

Installation Notes

Transponder key blanks must be cut to the correct key profile and then programmed to the target vehicle's immobilizer system using a compatible key programmer or diagnostic tool. Programming procedures vary by vehicle make and model and typically require a licensed locksmith or trained automotive technician. Always verify the correct transponder chip type and blade profile before cutting. Do not attempt programming without the proper equipment, as failed attempts may lock out the vehicle's immobilizer.
