We all love our classic GM rigs, whether it's a built OBS or a custom Astro van or any GM car. But absolutely nobody loves that harsh, ear-piercing piezo buzzer screaming at you every time you leave the key in the ignition.
It’s time for an upgrade.
Designed and hand-built right here at Ewalt’s Auto Tuning, our Custom Warning Chime Module completely replaces the obnoxious factory buzzer with crystal-clear, modern audio. Bring the premium, polyphonic chimes of a 2014+ Silverado into your classic truck—or load up any sound you want.
100% Customizable Audio: Features an onboard MicroSD card slot. Load up modern GM chimes, classic arcade sounds, a guitar riff, or even a voice recording. If it’s an MP3, your truck will play it.
Factory-Perfect Logic: Powered by a custom-programmed ATtiny84 microprocessor, this module doesn't just make noise; it perfectly mimics GM’s exact 4-state timing.
Headlamps On: Fast-paced warning.
Key In / Door Open: Medium-paced reminder.
Seatbelt / Ignition: Slow-paced chime synced perfectly with your dash warning light.
True Plug-and-Play: No cutting, no splicing, no wiring diagrams. Our custom-designed printed circuit board features the exact factory spade layout. Just pull your old black box out of the convenience center and plug this one straight in.
Premium Hardware: Built with an onboard voltage regulator, heavy-duty optocouplers to protect the circuitry, and a dedicated DFPlayer Mini audio chip for crisp, distortion-free sound.
Pre-Loaded & Ready to Roll: Ships fully loaded with modern 2014+ GM polyphonic chimes right out of the box. Want something different later? Just pop out the included MicroSD card and drop in your own MP3s.
Modernize your interior without cutting a single wire.
