Signal Restoration

KEYLOC’s patent-pending KEY™ algorithm automatically detects and analyzes crossovers, EQ, time delay, and all-pass filters in both factory and aftermarket gear. It level-matches left and right audio channels and corrects these filters for a smooth frequency response, delivering a clean, uncolored signal for your aftermarket system.

Hear It Yourself

Toggle the EQ correction on/off with the KEYLOC “KEY” button to compare before and after. If all-pass filters or factory time delays are detected, you can choose to keep the factory imaging or counteract it for precise tuning with an external processor, enabling a one-seat optimized sound experience.

Find the Frequency

Factory audio systems may not provide full-range signal on every speaker wire. KEYLOC allows you to connect the factory speaker wire and play test tones. Its LEDs indicate available frequencies: Low (20-200Hz), Mid (200-2kHz), High (2k-20kHz), giving instant insight into your signal.

It’s Fit

With KICKER’s FIT 2+™ (Fail-safe Integration Technology), KEYLOC supports versatile input sensitivity: 125 mV–10V (low level) with 60-Ohm smart load or 1V–40V (high level), making it compatible with nearly every vehicle on the road today.
