Remote Keyless Entry Solutions

Littelfuse Remote Keyless Entry Solutions defend the powered circuits and communication lines of modern vehicles that receive signals from a remote key-fob. These signals control features like remote starting, door unlocking, truck opening, and other custom commands. Littelfuse offers a range of fuses, TVS diodes, diode arrays, MOVs, MLVs, and ESD suppressors that protect the on-board circuitry from such threats.
